1. The space of the extremum mine microseism is closely connected with the high stress zones. 极值矿山微震发生的空间部位与高应力区密切相关。
2. Microseism, as a kind of regional monitoring means, is used to predict and forecast the great dynamic force calamity of the mine. 微震作为预测预报矿井重大动力灾害的一种区域性的监测手段，同时具有谱成分丰富、频带较宽的特性。
3. Studied the shock bump caused by the key stratum movement in Huafeng Colliery using the microseism locating and monitoring technology. 采用微地震定位监测技术对华丰煤矿关键层运动诱发矿震进行了研究。
