老虎台矿83001采区电磁辐射规律

Electromagnetic radiation regularities of No.83001 excavating area of Laohutai Coal Mine

摘要: 以抚顺老虎台矿83001采区煤岩体的电磁辐射为例,分析了采区煤岩体的电磁辐射与应力分布规律,并以此确定了冲击矿压防治的重点区域。

Abstract: Electromagnetic radiation(FMR) signals produced by coal and rocks in No.83001 excavating area of Laohutai Coal Mine,Fushun,were measured with electromagnetic radiation technology.The paper analyzed the electromagnetic radiation regularities and stress distribution of this excavating area.Based on that the key area of shock pressure in coal mine are determined.
