There has been a notable decline in the frequency and severity of mine explosions since the turn of the century. Among the major safety measures responsible for this decline are the use of rock dusting, development of permissible explosives and electrical equipment, improved ventilation and improved methods for detecting hazardous conditions. While these advances in mine safety are noteworthy, an examination of recent statistics indicate that the problem of mine explosion prevention is not completely solved. There is also growing concern over the number of frictional methane ignitions that occur annually; the frequency of methane ignitions has not as yet seriously impacted fatal accident statistics, but their potential for disastrous consequences is well known. This paper reviews recent research aimed at explosion prevention. Particular emphasis is given to the present practice of rock dusting and the implications of recent experimental evidence on the overall effectiveness of rock dust standards. Developments in supplemental explosion protection including devices for monitoring the explosibility of mine dust and passive and triggered explosion barriers are also discussed. The paper concludes with a section on frictional face ignitions and methods for their control.
