潘一矿二水平首采面综采矿压显现特征及控制技术研究

摘要

为了掌握潘一矿二水平综采面矿压显现特征,结合工作面地质和开采技术条件,通过回采期间综采工作面和两巷矿压观测,揭示采场和巷道矿压显现规律,得到综采面的来压步距,来压强度及回采引起的回采巷道变形情况,并提出了综采工作面及两巷的控制技术措施,为后续类似条件下工作面开采提供一定的参考依据.%In order to master appearance characteristics of rock pressure of the second level of fully mechanized coal mining face in Panyi No.1 Mine, combined with the geological and mining conditions, and through the observation of fully mechanized coal mining face and the two-roadway mine pressure, this paper revealed the appearance regularities of mine and roadway pressure, obtaining the weighting step in fully-mechanized working face, strength and the roadway deformation, and put forward control measures of the fully mechanized working face and the two lanes, providing a reference for the subsequent working face mining under similar conditions.
