摘　　要：针对川南古叙矿区观文矿段存在的矿井水害问题,在梳理观文煤矿地质及水文地质条件的基础上,分析了各含水层地下水对煤层开采的影响;以充水水源空间位置及水害形成条件为标准,将矿区内水害类型分为大气降水、老窑及采空区积水、煤层顶板水、煤层底板水与构造水5大类及可能的离层水害。针对不同类型水害对矿井的威胁程度及防治难易程度,提出了适合观文煤矿复合水害的防治水对策。Aiming at the problem of mine water damage in Guanwen section of Guxu mining area in southern Sichuan,based on the geological and hydrogeological conditions of Guanwen Coal Mine,the influence of groundwater of each aquifer on coal seam mining was analyzed.Based on the spatial location of water-filled water source and the formation conditions of water damage,the mine water damage in the mining area was divided into 5 categories,namely atmospheric precipitation,water in the old kiln and goaf,coal seam roof water,coal seam floor water and structural water,as well as possible water damage from separated layer.According to the threat degree of different types of water hazards to the mine and the difficulty degree of prevention and control,the prevention and control measures suitable for Guanwen Coal Mine complex water hazards were put forward.
