基于大水头煤矿西三采区煤层赋存条件、综放开采技术条件和地面电厂储渣库水体条件，利用我国煤矿放顶煤开采条件下的导水裂缝带观测成果，采用工程类比的方法，计算了西三采区放顶煤开采后导水裂缝带高度、保护层厚度、保护层和煤厚之比，分析了覆岩的隔水性，预计了坝体变形，论证了灰渣库水体下综放开采的可行性和安全性，研究认为灰渣库下方综放开采是安全的。
基于大水頭煤礦西三採區煤層賦存條件、綜放開採技術條件和地麵電廠儲渣庫水體條件，利用我國煤礦放頂煤開採條件下的導水裂縫帶觀測成果，採用工程類比的方法，計算瞭西三採區放頂煤開採後導水裂縫帶高度、保護層厚度、保護層和煤厚之比，分析瞭覆巖的隔水性，預計瞭壩體變形，論證瞭灰渣庫水體下綜放開採的可行性和安全性，研究認為灰渣庫下方綜放開採是安全的。

With west three coal seam occurrence condition in Dashuitou Coal Mine,fully mechanized caving mining technology and ground power plant slag pool water conditions,water flowing fractured zone observation results under sublevel caving,using engineering analogy methods,water flowing fractured zone height after sublevel caving,protection layer thickness,protective layer and coal thickness ratio,it studied water resisting strata,predicting dam deformation,it demonstrated ash storehouse feasibility and safety in fully mecha-nized sublevel caving mining under water body,it suggested that fly ash reservoir under fully mechanized top coal caving mining is safe.
