摘要
煤岩破裂产生震动的防治是世界性一大难题。从煤与瓦斯突出和冲击地压两方面对煤岩破裂产生的震动机理进行了分析,介绍了现行的几种较为成功的冲击矿压预测手段,其中详细介绍了钻屑监测预报法、微震监测预报法、电磁辐射预报法和综合预报法,对预测冲击矿压有较大的指导意义。
The prevention of quake produced by coal and rock break is a worldwide problem. In this paper, the mechanism of quake produced by coal and rock break was analysed from two aspects, coal and gas outburst and rock burst, the successful way of rockburst preven- tion used presently were also introduced, especially the prediction method of drilling bits-monitor, micro-seism monitor, electromagnetic radiation and the combination of several methods were expatiated in detail. All this have some reference to rock burst prediction.
