构造与巨厚砾岩耦合诱发冲击地压发生规律研究

Occurrence Regulation Study of Tectonic and Ultra-thick Conglomerate Coupling Induced Coal Bump

针对具有构造与巨厚砾岩特征的生产地质条件,首先,对义马矿区11个典型工作面发生的89次冲击事件进行统计分析,结合冲击地压的发生时序和发生位置,得出义马矿区冲击地压以回采巷道冲击地压为主,共发生51次,占57.3%。其次,指出冲击引起的回采巷道变形破坏以底鼓为主,并伴随上帮移出、下帮肩角鼓出等破坏。

According to the specific geological conditions of tectonic and ultra-thick conglomerate, firstly, statistical analysis of 89 coal bump incidents in 11 typical coal faces in Yima mining area were conducted, combined with the timing and location,could draw that Yima mining area coal bumps are based on mining roadway coal bump, there were 51 times, accounting for 57.3%. Secondly ,pointed out the impact of mining roadway deformation caused damage mainly to the kick drum and removed along with the help lower bulging shoulders help other damage.
