摘　　要：黄岩汇煤矿“三下”压煤量较大,矿井正常生产接续紧张,且使用常规垮落法开采煤炭容易造成地表沉陷和地下水及含水层破坏,从而导致地表建筑物损毁,大量矸石直接外排堆存。基于矿井实际情况,提出了连采连充采煤方案,并对工作面支巷布置、采煤充填工艺进行了设计。通过建立工作面FLAC^(3D)模型,并结合概率积分法进行计算,可以得知,使用90%、95%的充填率进行充填开采,可以保障地表铁路、建筑物损坏程度均处于Ⅰ级损坏范围内的标准要求。Huangyanhui Coal Mine has a large amount of coal in the areas under buildings,railways and water bodies,and the normal production continuity of the mine is tight.The use of conventional caving method to mine coal can easily cause surface subsidence and damage to groundwater and aquifers,resulting in the destruction of surface buildings and the direct discharge and storage of a large amount of gangue.Based on the actual situation of the mine,a continuous mining and filling scheme was proposed,and the layout of the working face support roadway and the coal mining filling process were designed.By establishing a FLAC^(3D) model of the working face and combining it with probability integration method for calculation,it can be concluded that using filling rates of 90%and 95%for filling mining can ensure that the damage level of surface railways and buildings is within the standard requirement of level Ⅰ damage.
