【摘要】 在总结近年来研究成果的基础上,结合大同矿区忻州窑矿开采条件及冲击地压发生的现场实际,综合运用现场实测、统计分析与理论分析等方法,从冲击地压发生的现象、特征、规律、原因以及发生机理等方面作了探索性研究,提出忻州窑矿"三硬"条件压缩型冲击地压发生的压变区域失衡冲击理论。并以此为指导研制实施了"三硬"条件"测、卸、支、断、护、避"六字综合防冲技术,使冲击地压发生频率和强度大幅下降,实现了具有冲击地压威胁煤层的安全开采。更多还原

【Abstract】 Based on summarizing research achievements in recent years,combined the mining condition and what rock burst happened of Xinzhouyao mine in Datong with field test,case analysis and theoretical analysis method to research the Phenomena,characteristics,reasons and occurrence mechanism,etc of rock burst,the changing pressure area imbalance theory on compressive type rock burst of coal in three-hard conditions has been build.And as a guide,the development of the implementation of.the "measure,relief,support,break,care,avoid" six word comprehensive anti-burst technology in "three hard" conditions,make the rock burst occurrence frequency and strength decreased significantly,Realized safety mining of coal seam which with the rock burst threat.更多还原
