摘要:
富水断层采动活化诱发涌水溃沙是地下煤矿开采中面临的典型隐蔽性动力灾害源之一,预测断层水患对安全开采具有现实必要性。文中通过对宁东矿区羊场湾煤矿的现场水文地质与开采技术条件调研与分析,总结得出该矿开采扰动区断层分布广泛,隐蔽性强,最大落差约32.0 m,最大涌水100.0 m3/h,最大含沙量12.0%,围岩易风化。采用综合防治技术,成功安全快速穿越了宁东矿区羊场湾煤矿12采区断层开采区域,保障了采掘接续和安全生产,为后期深部断层区开采诱发水患及灾害链防控提供了可靠适用方法,根据开采扰动区断层水渗流演化规律,为后期深部断层区开采诱发水患及灾害链防控提供了可靠应对方法。
Abstract:
Water-inrush and sand-burst around water-rich-fault is one of typical imponderable dynamic hazards due to mining-induced fault activation in underground coal mining.Inevitablely,it is essential to scientifically predict the water inrush around the large-gap fault for safe excavation.With detailed in-situ investigation and analysis of the hydro-geological and mining conditions in Yangchangwan coal mine,relative results showed distributions of faults were wide and concealed remarkably,crest of fault gap reached over 32.0 m,maximum value of water gushing was 100.0 m3/h and maximum amount of sediment sand was 12.0%,besides rock-masses were easily disintegrated.Finally the comprehensive prevention and reinforcement technology were proposed and their corresponding parameters were determined based on the combination of multi-unit control stability mechanism.Ultimately,the main ventilation roadway was successfully and rapidly tunnelled in No.12 panel.The innovative approach provided a reliable and appropriate method for the subsequent deeper mining-induced sediment disaster and their chain prevention and control adjacent to fault.
