电磁辐射对煤岩体应力异常区的响应
首发时间:2005-07-20
摘要:本文对断层带附近、褶曲附近、煤矿采掘工作面煤岩体中、隧道围岩中不同部位的电磁辐射及其分布规律进行了测试及分析。研究发现,电磁辐射对应力异常区反映较为敏感。用电磁辐射法进行地质构造勘探、评定煤岩体的应力状态是可行的。

Response of Electromagnetic Emission to Stress Abnormal Area of Coal or Rock
Abstract:In this paper, Electromagnetic emission and it’s distribution of coal or rock in different place nearby geological fault zone, fold or of working face in coal mine, wall rock in tunnel. Research shows that response of EME to Stress Abnormal Area is very sensitive. It is feasible to prospecting geological structure, assessing stress state of coal or rock.
Keywords: Electromagnetic emission;coal or rock;stress abnormity;prospecting
