This bibliography lists publications issued by the Bureau of Mines concerned with investigations on petroleum and natural gas. The items included are chosen for their continuing interest and value. It was recognized early that a list of petroleum and natural gas publications was needed for the Bureau's work, and unofficial publication of a ?straight forward? listing was begun. It was at first a chronological list; however, suggestions submitted by its users prompted a format change to show publications under broad, general topics. Author and subject indexes were developed, becoming more detailed with each new edition. This present list supersedes the ones compiled in 1949, 1952, and 1957, and several supplements, which were aside available to the public by the Library Of the Bureau?s Bartlesville Petroleum Research Center. The unofficial field publication came to be widely known nail in considerable demand by those who are primarily interested in the Bureau's publications on petroleum and natural gas so that it became, desirable to have it published as an Information Circular. It is hoped drat, this official publications will result in a wider and more effective use of the Bureau's research results which are reported in its publications.

"Under existing conditions in the treatment of oxidized lead ores containing small quantities of molybdenum no provision is made for the recovery of the molybdenum. Considerable quantities of this important element are lost in the slags of the lead smelters and constitute an economic waste. There is little or no probability that slag dumps containing molybdenum in small quantities could be economically treated for the recovery of the element, and steps for the prevention of waste in this respect must be taken prior to smelter treatment.Wulfenite, lead molybdate (PbMo04), and molybdite, molybdic ocher (Mo03), are the molybdenum minerals most abundantly found in deposits of oxidized lead ores. Wulfenite contains 39.3 per cent molybdenum trioxide and 60.7 per cent lead oxide; molybdite contains 66.7 per cent molybdenum and 33.3 per cent oxygen. Plumbojarosite, argentojarosite, cerussite, and occasionally anglesite are commonly associated with wulfenite ores, and the oxidized iron content is usually fairly high.The recent discovery and development of a body of wulfenite ore in the Star district near Milford led to a cursory microscopic examination of samples of the ore, followed by a few preliminary tests which had for their object the separation and recovery of the lead and molybdenum in separate products.The microscopic examination showed that the samples used in the work were composed of wulfenite, plumbojarosite, and a small quantity of cerussite, and indicated that the iron content was quite high. The ore was porous and yellowish-brown; crystals of wulfenite appeared to be quite uniformly distributed through it, and this mineral and plumbojarosite (Pb0.3Fe203.4S03.6H20) apparently accounted for the major part of the lead content, although lead"

Operation of underground coal mine mobile equipment is usually done in a restricted workspace with reduced visibility. This work environment puts machine operators in awkward postures for tasks that require awareness of their surroundings and fast reactions to avoid hazardous situations. Using experienced equipment operators as a source, researchers conducted an investigation that developed a method to gather data on the needs and practices of machine operators while controlling the machine and the reasons for needing particular operational cues. The method used was an interview technique including a survey questionnaire and visual aids. The data gathered defined operator cues and work positions for the cutting and tramming phases of remote controlled continuous mining machines used in underground coal mines. Analysis techniques to determine which cues an operator sees from a variety of positions utilizing a computer simulation is shown to be potentially useful to the mining industry for design of work practices and workplace layout and could impact equipment design and selection for improved worker safety. Conclusions indicate that the survey was a good research tool to collect data and helped investigators understand important visual cues. Using this information, researchers were able to analyze the visual cues an operator can see from a given work position and posture.

The industrial sand industry has been exploring new techniques to reduce dust. One company was experimenting with adding water during bagging operations to the surface of the hag, and into the product as it flowed into the bag. The Bureau of Mines, using instantaneous dust sampling instruments, measured the effectiveness of three methods of adding water. Results indicated that various types of water sprays applied in carefully controlled amounts could reduce dust up to 50% at worker locations at the bagging machine and inside a railroad boxcar. This report also discusses constraints such as product handling, customer acceptance, cold weather problems, dust collector performance, and other areas.

In the preparation of beryllium-copper alloys by fused-salt electrolysis, beryllium was electrowon from beryllium oxide dissolved in fluoride electrolytes and deposited on copper cathodes. At 880° to 1,030° C, deposition was on solid cathodes. Beryllium deposited on the copper, forming a liquid alloy that dripped from the cathode. Dripping alloys containing 3 to 4 weight-percent beryllium were produced with as high as 90 percent cathode current efficiency, by electrolysis at 910°.C. To prepare alloys of higher beryllium content, attempts were made at depositing beryllium on liquid copper cathodes. These efforts were generally unsuccessful, although alloys containing as much as 12 percent beryllium were prepared by this method. At temperatures of 1,100° to 1,300° C, requisite to maintaining beryllium-copper compositions as liquids, the beryllium reacted with cell structures.

A nomographical approach is proposed as a fast, easy-to-use, and reason- ably accurate method for estimating expected discounted cash flow (DCF) rate of return and payout time for onshore development drilling and oil production. All costs pertaining to drilling, completing, and equipping development wells, annual expenses of operation, maintenance, and taxes incurred in producing properties, and crude oil prices were considered in developing the nomographs. This report briefly outlines the origin, derivation, and use of the nomographs.

Engineering controls for overburden drilling include dry dust collection systems, wet dust suppression systems, and enclosed cabs [Zimmer and Lueck 1986; Volkwein et al. 1979]. Proper maintenance of the dust suppression system is critically important for drills using dry dust suppression methods. Failure to rigorously maintain these systems will result in inadequate dust control. Acute silicosis has been reported in miners operating equipment that relies on dry dust suppression [NOSH 1992].

This is the fourth and final article in a series that discusses underground fire-fighting preparedness. As with the previous three articles, it is based on interviews with 214 miners at 7 underground coal mines (referred to as Mines ?A? through ?G?) conducted by researchers of the National Institute for Occupational Safety and Health?s(NIOSH) Pittsburgh Research Center[Vaught et al. 1996]. The first article presented an overview of the study conducted by NIOSH on mine fire response preparedness and provided a general perspective on underground mine fires. The second article discussed miners? preparedness to evacuate a fire and their experience with incipient fires. The third article described miners? experiences in fighting underground mine fires and presented their perceptions of training and readiness for fire-fighting. This final article in the series offers suggestions to improve mine fire-fighting preparedness.

This paper describing the mining practices at the Engels mine is one of a series being prepared by the United States Bureau of Mines on mining practices, methods, and costs in the various mining districts of the United States. The Engels Copper Mining Co. operates two mines about 3 miles apart in Plumas County. Calif. Both mines send ore to the same mill, and the methods of the larger, or Engels mine, are described in this paper. Between 800 and 1,000 tons of 1-3/4 to 2-1/2 per cent copper ore are mined daily from this mine by a shrinkage method. Connection is made with the Western Pacific Railroad at Paxton by the Indian Valley Railroad, which is 22 miles long and operates a daily mixed train to the mine.

Benin's industrial sector experienced severe economic and financial problems in 1986, including disappointing performances of the Onigbolo cement plant and the Semé Oilfield, plus a shortage of technically trained personnel and experienced management. Oil production remained about 1,000 barrels per day. Import and export trade between Benin and the United States remained minimal. Because much of Benin's outstanding external debt was in U.S. dollars, the stronger dollar greatly increased the debt burden. The 1985 budget of $304 million' was composed of an investment budget of $194 million and a current budget of $110 million. Of the investment budget, 84% was expected to be externally financed. About $45 million was given to three priority projects: the joint Benin-Togo Nangbeto hydroelectric project scheduled for completion in 1986; drilling of new exploratory wells of the Semé petroleum project, and the Dassa-Parakou highway. The budget deficit was projected to exceed $43 million despite a decrease in projected revenue owing to an anticipated decline of 25% in import tax revenue, normally the largest source of Government revenue.

The Great Eastern nickel deposit is located in the western foothills of the Virgin Mountains in the Copper King or Bunkerville district situated in the southeastern part of Clark County, Nev. It is covered by a group of eight claims that can be reached by turning south from U. S. Highway 91 at Riverside, Nev., and driving about 12.6 miles southeast over a winding mountain road, which rises from about 3,000 feet to 4,000 feet in elevation. The climate is dry, with only a small amount of rainfall throughout the year. The temperature ranges from hot during the summer to short periods of freezing weather during the winter months. The vegetation is of the desert variety, and no timber is available for mining. Water for mining purposes would have to be pumped from lower areas. A granitoid gneiss comprises the largest part of the rock outcrops. It has a steeply dipping foliation that strikes about N. 75° E. The gneiss was intruded by basic dikes, which in turn were intruded by pegmatite dikes. The ore occurs as lenticular bodies formed by the convergence of several pegmatite dikes within the main dike. The principal sulfide minerals are pyrite, pyrrhotite, and chalcopyrite, which contain a small amount of nickel. Late in the year of 1939, the Bureau of Mines undertook an exploration project on the Great Eastern property to extend or delimit the known mineralization. Underground work, consisting of 590 feet of drifting and crosscutting, was completed in September 1940, and 1,091 feet of diamond, drilling for downward extension of an ore body in the Lower edit, which was completed in February 1941.

The mineral industry of Benin continued to be confined to the production of cement, crude oil, salt, and sand and gravel. Only crude oil and cement were exported, with the value of crude oil exports and cement exports constituting about 20% and 2% of export revenue, respectively. The value of crude oil exports was less than the cost of imports of refined petroleum products. Production of crude oil was unchanged from 1986, averaging 5,500 barrels per day (bbl/d). The Government managed the facilities at the Semé Oilfield while actively seeking a new manager to replace Pan Ocean Oil Co. of Switzerland, whose contract was canceled in 1986. Recoverable reserves of crude oil were estimated to be between 18 and 30 million barrels.

1. Mine drainage constitutes surface or ground water which flows from mines or mine sites and is usually characterized by concentrations of acidity or alkalinity. 2. The regional geology controlling the ground water flow pattern in conjunction with the life cycle mining plan can serve as a basis for making decisions about quality of water that can be expected to be encountered. 3. In regard to the prevention and control of acid water formation in underground coal mines, much is left undone in research and education: (A) Very little literature is available on this specific subject although much has been written on water management in underground mines. (B) Little or nothing is contained in the text books and curricula used in mining departments at colleges and universities with the result that educational offerings may be seriously deficient in these areas. 4. Prohibiting water entry into underground coal mines is the best method of preventing water pollution. Since this is not possible as mining operations are extended, preventing water or oxygen from contacting acid producing material may offer the next best alternative. 5. More emphasis is needed during the mine planning stage on steps to prevent water pollution. Such life cycle considerations as type of mining, sequence of development and spatial configuration as well as the elements of the drainage network and final network organization and extent must be considered.

"INTRODUCTION The Bureau of Mines began a broad program of exploration of various proportion in the Pine Creek area of the Coeur d'Alene mining region in the fall of 1943. As a part of this project, exploring was done at theLittle Pittsburg property in 1945. The work included driving a 500-foot crosscut from the No, 6 level and drilling four diamond core drill holes to test the behavior of the Little Pittsburg vein at depth. This report presents the data obtained by the Bureau.ACKNOWLEDGMENTSIn its program of exploration of mineral deposits, the Bureau of Mines has as its primary objective the more effective utilization of our mineral resources, to the end that they make the greatest possible contribution to national security and economy. It is the policy of the Bureau to publish the facts developed by each exploratory project as soon as practicable after its conclusion. The Mining Branch, Lowell B. Moon, chief, conducts preliminary examinations, performs the actual exploratory work, and prepares the final report. The Metallurgical Branch, R. G. Knickerbocker, chief, analyses samples and performs beneficiation tests.The Bureau's exploration of the Little Pittsburg vein was one of the activities of the Albany Division of the Mining Branch, S. H. Lorain, chief. The project was started by R. M. Gammell, mining engineer, and was continued by the author and J. R. Reynolds, assistant mining engineer.The chemical analyses included in this report were made at Reno, Nov., under the direction of A.C, Rice, acting engineer in charge, Rare and Precious Metals Experiment Station, Bureau of Mines.The cooperation and assistance of the management of the Denver Development Co. is gratefully acknowledged, in particular that of C. E. Nugent, who made available much of the operational data included in this report."
