Abstract:
Seventy percent of coalmine accidents in China not randomly occurred, but in serials. Most occurred on neighbor coalmine; some were even companied with earthquakes nearby. Certainly, some coalmine accidents occurred independently. It seems that some unknown elements controlled accidents. If these elements are made sure, and measures be taken, it would be of benefit for coalmine safety in production. (1) Coalmine shouldnt fall its rock freely, and there should be conformity among the coalmines. A unified, reasonable stress releasing plan should be made. (2) Neighbor coalmines accidents remind that some accidents may occur in its own mining space because stress in a larger scale is fluctuating. (3) A multicoalmine accidents notifying mechanism may need to be set up. Finally, the paper describes a stress monitoring system in which stress fluctuation is monitored, according to which coalmine can arrange its producing process.
