深部大采高综采工作面微震活动规律多因素分析

The multi-factor analysis on the deep large mining height fully mechanized mining face microseism activity rule

为探索深部大采高综采工作面冲击地压监测技术,基于现有的微震监测技术与装备,并结合采场布置与生产接续安排情况,研究了深部大采高综采工作面微震活动规律.对工作面从开面到"见方"阶段大量微震事件进行统计分析,得出诸因素如空间、时间、煤层及工作面生产活动对微震活动造成的一般性规律,为下一步同类工作面开采提供防冲监测依据.

To explore rock burst monitoring technology in the deep large mining height fully mechanized mining face, combining stope layout and production situation, we studied mining face microseism activity rule based on existing microseism monitoring technology and equipment. We analyzed a large number of microseism events of the working face from production to ＂Square＂ stage to find universal rules of the factors, such as space, time, coal seam and the working face production activity on microseism activity. This work can provide a basis for rock burst monito- ring technology in the same type working face.
