摘要
东古城矿z101工作面14~20m特厚煤层综放开采中,出现了强矿压显现现象,影响了工作面的安全高效生产。本文从已开采工作面的实际地质赋存条件入手,采用理论分析、物理相似模拟的方法,同时结合实测计算,对z101工作面强矿压显现进行研究分析,并提出控制强矿压的方法与技术途径。
During mining the Z101fully mechanized top coal caving face with14~20m extra thick coal seam in DongGuCheng mine,a strong mine pressure appearance has appeared,which has affected the safe and efficient productionof the face.This paper from the actual geological condition of working face,used the theoretical analysis method,physical simulation,and combined with the actual measurement and calculation,the Z101face strong mine pressurebehavior were analyzed,and put forward the control method of strong mine pressure and ways.
