矿山压力既是指分布于岩层内部各点的应力，又包括作用于围岩上，任何一部分边界上的外力，研究和实践已基本证明，未受构造运动影响的地区，处于某一深度的岩层中，矿山压力主要受上覆岩层的重量影响；而发生采动产生构造运动后，矿山压力的变化如何，本文就义桥煤矿2304采空区对2306工作面矿山压力的影响范围进行估算，论述了相应的防止措施。%Mine pressure not only refers to stress distribution in each point within the strata,and includes any part of the external forces on boundary effect on surrounding rock.The research and practice have proved,the area of not affected by the influence of tectonic movement,at a depth of strata,the mine pressure is mainly affected by the weight of overlying strata.Moreover mining after occurred the tectonic movement,how to change the mine pressure?In this article the influence range of mine pressure of 2304 goaf in Yiqiao coal mine for 2306 working face is esti-mated,and discusses corresponding preventing measures.
