|Remote control roof bolting is approaching reality with the continued improvement of a number of components and subsystems being developed by The Bendix Corporation under sponsorship of the U.S. Bureau of Mines and the U.S. Department of Energy. The era of remote control research in roof bolting was initiated by the USBM in June of 1973 with the award of a contract to Bendix Corporation to design and build a roof bolt bender/inserter device. One year later in June of 1974, the Bureau awarded five parallel R&D contracts to develop a longer-than-seam-height flexible roof drill. The Bendix flexible drill design has been the most successful of the five, has been thoroughly tested in both laboratory and underground situations, and has been incorporated into a number of machine applications along with the roof bolt inserter. The purpose of this paper is to discuss the advantages of remote control bolting from both a safety and productivity standpoint. Applications of the flexible drill and roof bolt inserter on a number of government and industry supported programs are used to illustrate the advances being made toward the goal of remote control.|
