摘 要:五里堠煤矿运输下山在掘进时巷道坡度由15°变为18°。根据水文地质资料情况,巷道的反向掘进段会穿过顶板破碎区且破碎区上方有含水层。为了保证生产安全,需要对顶板破碎段进行加固进而防治水。结合实际情况,采取了顶板管控注浆措施,并对施工参数进行了设计。现场结果表明,采取的注浆措施有效,可以有效地防治水。The roadway slope of Wulihou Coal Mine was changed from 15° to 18° during the transportation downhill driving.According to the hydrogeological data, the reverse tunneling section of the roadway will pass through the roof crushing area and there is an aquifer above the crushing area. In order to ensure safe production, it is necessary to reinforce the broken roof section to prevent and control water. Combined with the actual situation, the roof control grouting measures were adopted, and the construction parameters were designed. The field results show that the grouting measures adopted are effective and can effectively prevent and control water.
