摘　　要：为减少薄煤层掘巷工程量,在滨湖煤矿软底硬顶条件下实施了巷旁充填沿空留巷技术。利用力学模型计算了巷旁充填参数,并针对软弱底板优化了支护方案。实践结果表明:该方法支护方案可靠,留巷满足使用,经济社会效益明显。In order to reduce the tunneling of the thin coal seam,technology of gob-side roadway remaining is implemented in Binhu mine coal with hard roof and soft floor. Roadside packing parameters are calculated by using the mechanical model,and the support scheme is optimized to adapt weak floor. Practice results show that the method support scheme is reliable,while economic and social benefits are obvious.
