“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。
“兩硬“條件下的綜放工作麵頂闆控製難度較大，掌握其礦壓顯現規律對于指導“兩硬”綜放工作麵開採至關重要。以山西忻州窯礦8911工作麵為研究對象，通過現場實測掌握瞭該工作麵來壓步距、來壓彊度、動載繫數等礦壓顯現規律，建議適噹提高支架初撐力。
“량경“조건하적종방공작면정판공제난도교대，장악기광압현현규률대우지도“량경”종방공작면개채지관중요。이산서흔주요광8911공작면위연구대상，통과현장실측장악료해공작면래압보거、래압강도、동재계수등광압현현규률，건의괄당제고지가초탱력。
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 .
