摘　　要：针对目前我国煤矿冲击地压频繁发生的实际情况 ,本文以山东华丰矿为例 ,通过对地表下沉与冲击地压的关系进行了理论研究和数值计算 ,总结了两者之间的内在规律性 ,指出地表下沉速度与冲击地压的发生有基本的对应关系 ,其具有反弹效应、波段效应和滞后性 ,并提出了以地表下沉速度为监测指标的新的冲击地压预测与防治手段 。In view of the situation that rock burst happens frequently in our country now, the inner characteristics of surface subsidence and rock burst are discussed in this paper. Based upon Huafeng coal mine as an example, it points out that there is a basic corresponding relation between surface subsiding velocity and rock burst in a new view, which have inverse spring effect, wave band effect, lagging character. The rule of the relation is summarized and numerical analyzed which will contribute to the prediction and prevention of rock burst. The conclusion of theory study and numerical simulation will play roles in rock burst research in the future.
