摘　　要：放顶煤开采技术的广泛应用增大了毛煤中的可见矸石量,而这部分矸石降低了矿井的实际产能。若采用动筛排矸工艺将这部分矸石在升井前排出将会取得巨大的社会经济效益。文章结合矿井水处理提出了毛煤井下动筛排矸工艺方案,以期通过两个系统的有机组合同时解决毛煤含矸和井下水仓清淤两个难题。The widely use of caving mining technology increases the percentage of visible refuse content in the ROM coal; this part of refuse reduces the actual capacity of the mine. Discharging this part of refuse using moving deck jigging before rose will receive great social and economic benefits. So a combination process, which was composed with move deck jigging process and mine water disposal technology, is proposed. Two difficult problems: refuse content and mine sump cleaning shall be solved by this process.
