摘要
根据陕西彬长矿区特厚煤层及覆岩含水层丰富的赋存特点,通过数值分析方法研究了巨厚洛河组砂岩含水层下特厚煤层高强开采条件下覆岩破坏规律,综合考虑地质条件、开采技术条件等因素,确定了首采区顶板突水危险性及限高开采、疏水降压为一体的综合灾害防控技术。
Based on the occurrence features of extra - thick seam and water - rich overburden in Binchang Mining Area, the failure characteristics of Luohe thick sandstone aquifer under high - strength mining are analyzed by using the numerical simulation method. Considering the geological conditions, mining conditions and other factors, the water inrush danger and comprehensive control technolo- gy were proposed which consists of height permitted mining and depressurizing.
