摘要

简单介绍了微地震监测的原理,结合华丰煤矿的具体应用情况,介绍了微地震监测技术的应用方法、特点及其效果。应用矿山压力理论建立了华丰矿采场顶板运动规律模型,并计算得出了直接顶和老顶的范围。与微地震监测结果比较,发现两者结果基本一致,证明微地震监测可以用于预测顶板运动规律。微地震监测技术对确定采场覆岩“两带”高度、预报采场顶板破坏、预测煤与瓦斯突出,从而预防灾害发生、保证煤矿安全生产并提高资源回采率等具有重要意义。
The theory of microseismic monitoring technique is introduced.Combining the situation used in Huafeng Coal Mine,the used method,the characteristics and the effect of microseismic monitoring technique are explained.The behavior model of the roof was given according to the situation survey result.The scopes of the immediate roof and main roof were calculated adopting the mining pressure theory.And the results are almost the same as that of microseismic monitoring.This indicates that the results of microseismic monitoring are reliable.Microseismic monitoring technique is of important meaning for the safety of coal mine,the prediction of the period of mining pressure and the increase of recovery rate.
