一种矿用L型钢柱鞋的设计与应用

Design and application of a kind of L-shaped steel shoes for mining

为解决无巷旁密集单体支护的沿空留巷采空区侧压力的难题,山西冀中能源集团金晖荣泰矿设计并制作了一种矿用L型钢柱鞋,与支护组件配合有效提高了沿空留巷整体支护结构的围岩抗变形能力,减小了沿空留巷整修巷道的成本,同时延长了沿空留巷的服务年限,避免了沿空留巷采用无巷旁密集单体支护方式的大量整体失效,确保了沿空留巷顶板管理的安全、可靠。

In order to solve the problem of side pressure along goaf without the support of dense monomer beside the roadway,a type of mine L type steel column shoe was designed in Jinhui Rongtai Mine,which could effectively improve the anti deformation ability of the surrounding rock of the holistic retaining structure along the goaf,and greatly reduce the roadway refurbishment along the goaf.The cost of the road has also extended the service life of the roadway along the gob,and avoided the large amount of overall failure of the roadway along the goaf with the way of the dense single support,ensuring the safety and reliability of the roof management of the roadway.
