摘　　要：结合具体条件进行了巷旁充填支护参数设计 ,在矿压观测基础上 ,分析了留巷围岩变形及充填体载荷特征 ,把高水速凝充填材料沿空留巷与炮掘及综掘成巷方法进行经济对比 ,结果表明 ,该留巷方法有明显技术和经济优势 ,在晋城矿区 9号煤中有很好推广应用价值 .The design of the support parameters for roadside packing have been drawn out by the current condition.On the basis of rock pressure in mine observation,the features of the deformation of surrounding rock and support load of gob*.side entry are analysed.Economic effects of the ways of taking roadway of the high*.water packing for gob*.along roadside with blast excavation and full*.mechanized excavation have been contrasted.Te result shows that the gob*.along roadside has obvious advantage in the technology and economy.And it has support values for the coal No.9 in Jincheng coal mining area.
