摘要
依据神东矿区补连塔煤矿12413浅埋近距离综采工作面过上覆11煤空巷的实际情况,通过现场写实、理论分析和数值计算及现场实验相结合的研究方法,分析了12413工作面过上覆11煤空巷之前、过空巷时、过空巷之后12413工作面推进过程中矿压显现规律和12413工作面过平行于推进方向、垂直于推进方向的上覆空巷期间的矿压显现规律的研究。
According to the actual situation of 12413 shallow buried close distance fully mechanized working face passing through overlying 11^# coal empty roadway in Bulianta Coal Mine in Shendong Mining Area, through the combined research method of field research, theoretical analysis and numerical calculation and field experiment, in this paper, the laws of strata behaviors in the advancing process of 12413 working face before, during and after passing through overlying 11^# coal empty lane are analyzed, and the laws of strata behaviors of 12413 working face passing through overlying empty lane which is parallel to the advancing direction or perpendicular to the advancing direction are studied.
