发布时间：2018-11-17 06:26
【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。
[Abstract]:Water in goaf is the hidden danger of coal seam mining in close distance. Based on the analysis of water inrush source, the characteristics of mining fissure development and its connectivity with goaf, and based on the comprehensive analysis of geological conditions, the scope of water accumulation in the goaf of upper coal seam is found out by using the method of geophysical exploration and drilling. The static storage water in the goaf is sparsely released, and the hidden danger of mining in the coal seam is eliminated.
