摘要
近年来,随着我国火工品控制越来越严、高瓦斯矿井安全管理、浅埋爆破控顶易对地面构成一定威胁等原因,水力压裂切顶卸压技术得到逐步推广和应用。本文结合寺河矿东五盘区东翼四条盘区大巷矿区特点,研究设计水力压裂切顶方案,以期望在采空区达到"增透、卸压、防突"的作用,从而实现真正的快速达标、经济防突的目的。
In recent years, with the increasingly more and more strict control to the explosive, aiming at the high gas coal mine safety management and the threat on the ground caused by blasting topping, the hydrofracture topping has been gradually popularized and applied, in this paper, combined with the panel roadways characteristics in Sihe Mine East five area, researched and designed the hydraulic fracturing topping scheme, in order to get the increasing permeability, relief pressure and eliminating outburst ＂role in gob, and realize the fast target, the real economy to outburst.
