厚煤层工作面矿山压力显现规律研究

Study on the Law of Mine Pressure Appearing in Thick Coal Seam Working Face

本文以西山煤电马兰矿18303工作面为研究背景,通过工作面矿压观测的方法,研究该工作面矿压显现规律,本次矿压观测按照回采顺序划分成两个阶段:工作面正常回采阶段和工作面进煤柱阶段,分阶段进行研究。研究成果对马兰矿18303工作面顶板合理有效支护具有重要意义。

This paper takes the 18303 working face of the Malan Mine in Xishan Coal and Electricity as the research background. Through the method of observation of the pressure in the working face, the law of mine pressure behavior in the working face is studied. The mine pressure observation is divided into two stages according to the mining sequence: normal mining stage and coal pillar stage of the working face, and the research is carried out in stages. The research results have important significance for reasonable and effective roof support of 18303 working face in Malan Mine.
