高家堡矿井工作面底板集中泄水巷疏排水设计

Water drainage design of working face floor centralized drainage roadway in Gaojiabao Coal Mine

针对高家堡煤矿工作面及采空区涌水疏排难题,介绍了工作面底板集中泄水巷疏排水技术。研究了工作面底板集中泄水巷布置方式、数量、层位、断面、坡度等内容,并总结了底板集中泄水巷的主要优点及其适用条件。结果表明,布置底板集中泄水巷是解决矿井采煤工作面及采空区涌水疏排的有效途径,对保障此类矿井安全生产具有重要实践意义。

Aiming at the problem of water discharge and drainage in working face and goaf in large water mine, the technology of centralized drainage tunnel at the working face floor are introduced, taking Gaojiabao Coal Mine as an example. The layout, quantity, horizon, section and slope of the centralized drainage roadway in the working face are mainly discussed, and the main advantages and applicable conditions of the centralized drainage roadway in coal seam floor are summarized. The results show that the layout of the centralized drainage roadway is an effective way to solve the water inrush and drainage in the coal mining face and goaf of the large water mine, which has important practical significance for ensuring the safety production of such mines.
