近距离煤层采空区水害探测与防治

摘要

近距离煤层开采时采空区积水是下煤层开采的安全隐患.通过突水水源、采动裂隙发育特征及其与采空区的连通性分析,以地质条件综合分析为基础,采用物探与钻探相结合的探放水方法,查明了上煤层采空区积水范围,疏放了采空区静储量积水,排除了下煤层开采的安全隐患.%Goaf water was potential safety hazard of lower coal seam mining in contiguous coal seams,and connectivity between water inrush resource,mining fractures development character and goaf was analyzed,it taking geological situation synthesis analysis as base,water detection and release method with geophysical prospecting and drilling was applied,goaf water scope of upper coal seam was identified,goaf water was drained,and potential safety hazard of lower coal seam mining was excluded.
