含水破碎带及断层临近矿体安全采矿技术研究

针对有破碎带及断层赋存并临近地下铁矿山矿体的开采,如果破碎带及断层中含水,随着开采的进行及空区的加大,含水破碎带及断层会产生变形、失稳及断裂破坏,给采场带来严重的冒顶、塌方或突然涌水等严重的灾害事故,对含水破碎带及断层临近矿体的开采进行研究,通过稳定性分析及模拟计算,研究制定了保证安全的采矿技术方案。

Study of Safety Mining Technology for Ore Body Close to Water-bearing Crushed Zone and Fault

As mining of ore body of an underground iron mine that was close in a crushed zone and a fault,if there was water in the crushed zone and the fault,deformation,instability and fracture would take place in the water-bearing zone and the fault,resulting in serious caving,collapse or breaking through of water of a stope.Mining in the water-bearing crushed zone and the fault close to the ore body were investigated.On the basis of analysis and analog calculation of stability,the safety mining technical scheme wa...
