“两硬”综放工作面矿压显现规律实测研究

摘要

It is critical to grasp the laws of strata behavior in guiding the mining of“Two hard” fully mechanized caving face because of the difficult controlling roof in fully mechanized caving face under the condition of “Two hard” .Taking 8911 work face of Gao Colliery ,Xinzhou ,Shanxi as the research subjects ,the author grasps the laws of strata behavior such as stress pace ,stress strength and dynamic load coefficient and suggests support setting load should be properly improved .%“两硬“条件下的综放工作面顶板控制难度较大，掌握其矿压显现规律对于指导“两硬”综放工作面开采至关重要。以山西忻州窑矿8911工作面为研究对象，通过现场实测掌握了该工作面来压步距、来压强度、动载系数等矿压显现规律，建议适当提高支架初撑力。
