摘要
通过现场矿压实测的方法,研究了神华集团大柳塔煤矿22614综采工作面在薄基岩厚煤层开采条件下的矿压规律。在表土为松散砂土情况下,把工作面上部基岩厚度起伏变化以及支架的受力特点结合起来综合分析研究,为实现浅埋深综采工作面安全高效回采提供依据。
Through the mine pressure measurement was studied with the method of shenhua group daliuta coal mine 22614 fully mechanized working face in thin bedrock thick coal bed mining conditions of mine pressure regularity.In the surface soil for loose sand,face the upper bedrock ups and downs change and support＇s stress characteristics together integrated analysis for the realization of shallow buried depth of fully mechanized working face safety and efficiency mining provides the basis.
