摘要
公乌素煤业公司在021201薄煤层综采工作面成功应用柔模混凝土沿空留巷技术,并对柔模混凝土沿空留巷技术的巷旁支护设计、回采期间巷道变形与矿压进行了分析,证明柔模混凝土沿空留巷技术,不仅能够减少区段煤柱损失、提高技术经济效益,而且柔模混凝土沿空留巷能够满足巷道使用要求及安全生产需要,是一种实用、成熟的开采工艺,对其他煤矿应用柔模混凝土沿空留巷技术,具有现实的指导意义。
Wuhai Gongwusu Coal Co.,Ltd. at 021201 Thin Seam Mining Face successful application of soft mold concrete gob technology, and the soft mold concrete gob Lane offshoot protection technology designed roadway deformation during recovery pressure were analyzed with mine proved flexible mold concrete gob technology can not only reduce the loss of coal pillars ,im-prove technical and economic benefits, and the soft mold concrete gob roadway to meet production needs and safety require-ments,is a kinds of practical,proven mining technology,soft-mode applications to other coal gob of concrete technology has practical significance.
