摘　　要：为解决隐伏向斜构造复杂区回采工作面强涌水与井下泥石流问题,以东欢坨矿2286工作面为例,采用高密度电法探测技术结合地质构造控水理论分析,得到了该工作面含水层径流与富集规律,并提出了工作面超前疏放水方案。结果表明:对井下煤水混合致灾问题,可采用强排水、煤水流量控制与煤水分离联合技术,在强径流富水区宜采用密集多孔疏放水技术,实现静储量快疏、动储量少疏;为预防煤水泥灾害,应建设完善井下强排水与分流系统,对工作面出水点、工作面积水区在巷道内及早实现清水收集与分流,因地制宜地采用多级振动筛、沉淀池并配合刮板输送机对煤水混合物进行井下分离与自动转运,采用这些合理措施,消除了在强涌水情况下2286工作面被淹没的危险。In order to solve a high water inflow in the coal mining face and mud-rock flow problems of the complicated hidden syncline structure,based on No. 2286 coal mining face of Donghuantuo Mine as a case,with application of detection technology with high density resistivity method,in combination with geological structure water control theory analysis,runoff and enrichment law of the aquifer in the coal mining face was obtained and an advance water discharging plan of the coal mining face was provided. The results showed that disaster caused by the coal and water mixed could be solved with high water discharging,coal and water flow control and coal and water separation three step combined technology. In the high runoff watery zone,a dense multi boreholes water discharging would be suitable applied to realize quick discharging of static water reserve and less discharging of dynamic water reserve. To prevent coal water mixture,high water discharging and water separation system should be well established in the underground mine. A clean water collection and separation should be set up and realized as early as possible in the mining gateway for the water inflow point and ponding area in the coal mining area. According to the local conditions,multi stage vibration screen and sedimentation tank with scraper conveyor could be applied to separate and auto transfer the coal and water mixture. With scientific design,rational measures applied could eliminate water flood danger of the coal mining face under the high water inflow condition.
