| 摘 要： | 中国70%以上的矿井灾害并不是随机发生的,而是沿着灾害矿井周边向其他矿井"扩散"。这种"扩散"既包括同类事故,也包括不同类型灾害;有些灾害事故还伴随周边地震活动。当然,也有一小部分灾害事故孤立发生。这些现象显示矿井灾害事故似乎存在一定规律,如果能够掌握并加以利用,具有多方面的意义:(1)各矿区进行统一、科学、合理的释放应力,制定更全面的卸压方案;(2)对于矿井密集的地区,每个矿区要了解周边邻近县市煤矿采掘点、构造应力场、区域应力场情况,在制定开采方案过程中,除了保证自身卸压需要,还要保证整个大区的应力平衡;(3)各煤矿大区需建立灾害通报机制,进行灾害预警,提前防范。彼此掌握大区灾害情况,以利于煤矿生产防灾、减灾。最后,文章提出了开展中场、近场地压监测的设想,并就地压监测与煤矿生产运行进行初步描述。

| 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 shouldn't 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 multi-coalmine 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. |
