| 摘 要： | 针对回坡底煤矿回采巷道煤柱尺寸大,资源浪费严重问题,开展了留7 m窄煤柱沿空掘巷的实践。结果表明,窄煤柱沿空掘巷采用锚梁网索支护技术,实现了巷道围岩稳定,能够满足安全生产的需要。窄煤柱沿空掘巷在高强度锚梁网索支护技术下具有较大的推广应用价值。

| Abstract: | According to the practice and the coal waste of wide supporting pillar remained for mining roadways,experience of roadway driving along gob was practiced in Huipodi colliery.The results indicates that roadway driving along gob which supported by 7 meters narrow pillar and high-strength bolt-beam-mat reinforcement-anchor rope technique,can maintain stabilization and satisfy the need of safe production,and has large value of generalization and application. |
