摘要
矿井80%的突水事故都与断层有关。我国部分学者从导水裂缝带、突水通道等角度对断层引发突水进行了分析,本文以山东某矿井突水事故为工程背景,从顶板运动演化角度对断层活化、顶板突水机理进行分析,揭示出这起看似普通的突水事故背后,断层附近顶板运动演化规律和导水通道的形成,并对相似条件下工作面开采提出了防治措施。
80% of the mine water inrush disaster is related to fault. Some scholars in our country analyzed the water inrush disaster caused by fault from the water flowing fractured belt, water inrush channel, taking shandong mine water inrush accident as the engineering background, from analyzed the fault activation, roof water inrush mechanism from the roof movement evolution angle, revealed the roof movement evolution rules near the fault and the water flowing passage formation, and puts forward prevention measures for the similar working face under the condition of mining
