摘要 煤矿开采过程一直存在综采工作面过空巷问题。通过现场监测,酸刺沟煤矿综采队获得了顶板下沉的一些数据,掌握了浅埋大采高煤层过空巷前后周期的来压状况,并且预测了周期来压,以及评价了通过停采等压、局部工作面调斜等手段对来压时间及强度的控制效果,本文着重对浅埋大采高煤层过空巷时矿压的规律进行了研究,旨在为更好地促进我国西部浅埋大采高煤层工作面过空巷,进而更好地进行煤炭开采工作。 The problem of goaf crossing in fully mechanized coal mining face has always existed in the process of coal mining.Through on-site monitoring,the full-mechanized mining team of Suancigou Coal Mine acquired some data of roof subsidence,grasped the weighting condition of the period before and after crossing the goaf roadway in shallow and large mining height coal seam,predicted the periodic weighting,and evaluated the control effect of weighting time and strength by means of stopping mining isobaric and adjusting inclination of local working face.This paper focuses on the study of the law of rock pressure in goaf roadway of shallow and large mining high seam,in order to better promote the goaf of shallow and large mining high seam in Western China,and then better carry out the coal mining work.
