高水材料巷旁充填沿空留巷技术研究与应用

Research and application of high water content material for roadside packing to go with gob-side entry retaining technology

简要介绍了邯矿集团陶一煤矿12701工作面沿空留巷的设计方案和实施过程,分析了高水材料巷旁充填沿空留巷与传统留巷方案相比具有的优点,指出了方案实施中存在的问题。

From the angles of coal seam occurrence, rock characters of roof and floor strata, geological tectonics, hydrology and the damages left over by small coal mines, this paper presents a brief introduction to the overall geological conditions of #12701 coal face in Taoyi mine, Handan Mining Group. Also described are the design scheme and its implementation of the gob-side entry retaining project in # 12701 face. A comparison made of the use of high water materials in roadside packing and traditional gob-side entry retaining practice results in advantages of the former over the latter. The paper also points out the remaining issues in the implementation of the design scheme.
