摘　　要：为了保护水资源和保证矿区持续发展，基于对采空区薄夹矸下顶板裂隙漏风、漏水规律分析．提出了薄夹矸下巷道向顶板采空区和相邻煤层采空区漏水、漏风的封堵方法，形成了采空区薄夹矸下回采巷道防漏技术方案。结果表明：当采空区厚度3-5m时，采用高分子材料喷涂封堵技术；当采空区厚度在3m以下，采用注浆封堵技术，密封效果明显。In order to protect the water resources and guarantee the sustainable development of the mining area, based on analysis of the goal under the thin thick roof fissure air and water leakage, putting forward the plugging method in mined-out area and adjacent to the roof of roadway , formed a thin goal dirt band extraction roadway under the leak proof technology solutions. The results show that when the thickness of the mined-out area has about 3 -5 m, adopt the polymer coating technology; when the thickness of the goal under 3 m, adopt the grouting sealing technology, sealing effect is obvious.
