厚煤层综采面过断层群矿压规律研究

Study on strata pressure of over fault group in fully mechanized coal seam with thick coal seam

文章以辛置矿2-109B工作面过断层群为工程背景,采用无线电坑透和瞬变电磁法对工作面地质构造进行了探查,通过数值模拟分析了工作面过断层群时的矿压显现规律,结果表明工作面进出断层群和在断层群中推进时矿压规律有明显不同。研究结果对109B工作面回采具有一定指导意义,也对相似条件工作面提供了借鉴。

In this paper,the faults group 2-109B working face in Xinzhi Coal Mine is taken as the engineering background.The geological structure of the working face is probed by using radio pit penetration and transient electromagnetic method.By means of numerical simulation,the results show that the law of rock pressure is obviously different when the working face moves in and out of the fault group and advances in the fault group.The research results have certain guiding significance for the mining of the 109B working face and also provide reference for the working face with similar conditions.
