煤矿冲击地压电磁辐射临界值判定

Coal rock burst of electromagnetic radiation to determine critical value

冲击地压是矿山压力显现的一种特殊形式,又称岩爆或煤炮,是地下采矿工程中最具威胁的动力灾害之一。冲击地压不仅损坏支架和巷道,导致矿井不能维持正常生产,严重时会危及井下人员的生命安全。因而系统的、深刻的对冲击地压进行研究具有重要的理论意义和实际意义。本文以某煤矿1305工作面为实例,根据现场实际条件,采用电磁辐射法对1305工作面进行电磁辐射临界值判定。

Rock burst also known as rock or coal burst. It is a special form of pressure behavior, and one of the most threatenest force disas- ter in the underground mining engineering. The rock burst not only damage the supports and roadway, leading to the mine can not maintain the normal production; but also threaten the lives of workers. Therefore the system and a profound study of the burst has an important theoretical and practical significance. In this paper, for instance 1305working face, using EME measure decide critical value.
