Discussion at the North of England Institute of Mining and Mechanical Engineers' general meeting held in Newcastle-upon-Tyne, 3rd June 1916, on the paper published in Trans. I.Min.E., vol.LI, 1916, p.361-377, comprised written comments by Ashworth J. on the practicality of applying quenching materials to a dust cloud ahead of the explosion flame

Application of the Internet of Things (IoT) technologies - the interconnection of uniquely identifiable embedded computing devices within the existing internet infrastructure - to the mining industry is discussed. IoT technologies are aimed at making projects safer, better optimised and more economic and are applicable to current or new underground or open-pit mines, regardless of size. Two examples are presented of successful implementation of IoT technologies, the Chelopech gold, copper and silver mine in Bulgaria, where production has increased from 500 000 to 2 000 000 tonnes/y and communication costs have been reduced by US $2 500 000 over 2 y, and the Pilbara project in Western Australia, where remotely controlled wirelessly connected autonomous trucks have covered ca. 3 000 000 miles and hauled almost 250 000 000 t of ore since 2008

"Opening statements relating to the health and welfare of underground workers and the nature and prevention of silicosis and pneumokoniosis. During 1945-47, 10,500 UK coal-miners were certified by the Silicosis Medical Board to be suffering from pneumokoniosis and suspended from work in the industry. Over 80% of cases occurred in the South Wales coalfields. Silicosis and pneumokoniosis also occur among metalliferous miners, such as the tin-miners of Cornwall. The slate-quarries of North Wales are also troubled by these conditions as are the haematite mines of the North-West of England."

Davy saw science to be the ultimate truth. He loved the utility and permanence of it and the feeling of progression. He was a bold chemist and an inventor, but he thought like a writer

The self heating of coal, or spontaneous combustion, has been a problem for centuries. This symposium addresses the issue.

Many novel projects suffer delays, cost overruns or failure because of inadequately qualified technologies. A new qualification to measure the quality of innovation is discussed.

Paper presented at the conference Economic geology in Europe and beyond II, models for mineral deposits in sedimentary basins, held in Keyworth, UK, 13-14 April 1994 (originally entitled: The Broken Hill base metal deposit - a tectonically transported and modified basinal deposit within the Proterozoic Willyama fold and thrust belt). A regional structural study was undertaken which incorporated the role of shears. Their positions were identified from earlier mapping, from regional aeromagnetic data and by additional field work. Kinematic studies determined movement histories and petrological studies of the fault rocks formed within the shears identified the relationship between the movements and regional metamorphism. It was found that the shears formed a part of an earlier, major thrust event with transport from NW to SE and a later, minor one in the reverse direction. Neither had any significant effect on the mineralisation apart from local displacement, but the shuffling of the basin stratigraphy adds to the difficulty of recognising the original volcanic and sedimentary protoliths of the metamorphosed sequence. The mineralisation at Broken Hill mine is confined to a single recognisable thrust slice within a shear corridor. It is stratabound with locally transgressive remobilisation due to the high-temperature thrusting and some metasomatic alteration as a result of the retrograde shearing. This variation accounts for the different genetic models applied to the deposits in the past

It is shown that most of the variation in the results of semi-batch flotation tests is related to the unavoidably stochastic nature of the flotation process. The preparation and analysis of flotation samples and, to some extent, operator error in performing the flotation test procedure are responsible for a small proportion of the observed variability of the calculated flotation performance indices

The Parliamentary Under-Secretary of State at the UK's Department of Transport introduced the symposium, approved its emphasis on environmental planning and the mitigation of environmental impact, discussed the publicity resulting from the recent opening of the Channel Tunnel as well as the role of private financing, and pointed out the leading role played by the Department of Transport in the introduction of the New Austrian Tunnelling Method to projects such as the Jubilee Line extension and the Heathrow Express (an editor's footnote, however, mentions with regret the Heathrow subsidence that occurred just before the journal went to print)

Mines are facing fresh challenges over how they deal with the huge quantities of water consumed. industry analyst Frost and Sullivan, demand for treatment equipment and services alone is expected to be worth US$3.6bn by 2016, while a report by consultancy Bluefield Research estimates that the total mine water market - which includes water infrastructure such as reservoirs, pipelines and dewatering systems as well as the equipment and services - will be worth US$17bn by the end of 2019. Methods of water decontamination are described.
