摘　　要：结合康家滩矿 8号煤层 8810 1工作面地质采矿条件 ,进行了直接顶初次垮落步距、老顶初次来压步距和周期来压步距的理论预测 ,与实际开采实践基本吻合 ,有效地指导了康家滩矿首采 8810Combined with the geological conditions,theoritical prediction of first caving distance,first weighting in old roof and circular weighting distance are made,which is coincided with mining practice and effectively supply a guidence for the mining in 88101 face of Kangjiatan mine.
