| 摘 要： | 根据含水层下矸石充填采煤覆岩移动变形特征,对等价采高的计算公式进行了细化和修正,并利用此修正的公式对不同充实率的情况下进行预计导水裂隙带高度,实践开采得出结论:含水层下矸石充填对覆岩移动变形产生有效控制,导水裂隙带预计高度和实测结果二者大体一致。

| Abstract: | Gangue filling mining overburden rock movement and deformation characteristics under aquifer are analyzed in order to study the affect of gangue filling percentage under aquifer on development height of water flowing fractured zone, development height of water flowing fractured zone is calculated under different filling percentage by using optimized and modified calculation formula of equivalent mining height, practical mining shows that gangue filling under aquifer can effectively control the movement and deformation of overburden rock, measured result are basically consistent with expect results of development height of water flowing fractured zone |
