The introduction and advancement of remote roof bolting in coal mines

Mining Engineering, 2017, Vol. 69, No. 3, pp. 16-16
Burgess, Robert; Gill, Dale; Steyn, Jaco; Kyslinger, Bill


PREVIEW:

With mining, especially coal extraction, comes the necessity of supporting the roof. Since the 1950s, the primary method for roof support has been the use of roof bolts. Roof bolting is considered one of the most hazardous jobs in underground coal mining. In 2004, there were 3,405 injuries reported to the U.S. Mine Safety and Health Administration (MSHA). Of those injuries, 17 percent were associated with bolting machines (593 injuries). The majority of the injuries resulted from rock falling from supported roof. However, injuries involving a part of the body being struck by, or caught between, during bolting and drilling occurred with relatively high frequency (Burgess and Steiner, 2007).
