6m大采高沿空留巷巷旁支护研究
Study on Road-side Support Technology of 6m High Cutting Working Face
【摘要】 为了适应大采高工作面沿空留巷,在霍尔辛赫煤矿6m大采高工作面进行了柔模混凝土沿空留巷支护设计。重点设计研究了巷旁支护参数、底板加固参数、临时加强支护参数。结果表明:6m大采高工作面柔模混凝土沿空留巷支护参数合理,效果良好,具有良好的经济效益和应用前景。
【Abstract】 In order to adapt to the gob side entry retaining in the high cutting working face,the support design of flexible formwork concrete gob side entry retaining is carried out at 6 m high cutting working face in Huoer Xinhe Coal Mine. The parameters of road-side support,floor reinforcement parameters and temporary strengthening support parameters are mainly designed and studied. The results show that the support parameters of flexible formwork concrete for gob side entry retaining in the working face are reasonable,and the effect is favorable,providing good economic benefits and application prospects.
