云煤一矿炮采工作面矿压显现规律研究

Based on the strata behaviors observation and analysis in blasting mining face in Yun-mei the second coal mine. The paper discussed the characteristics of strata behavior in the blasting mining face and roadway abutment pressure distribution. It will provide references for understanding and graspjing laws of blasting mining face strata behaviors, determining a reasonable working resistance of the pillars and roof management way for roadway and the face. Meanwhile, it will have significances of scientifical guidance and reference for blast mining surface mining of the mining or other similar and geological conditions.
