摘要
煤矿井下开采时巷道布置方式和采煤技术选择至关重要。在开采设计时,需要根据煤矿的地质条件选择合适的巷道布置方式和采煤技术。分析了不同地质条件下的巷道布置方式,主要包括多煤层开采巷道布置、特厚煤层开采巷道布置和薄煤层开采巷道布置,探讨了选择采煤技术时考虑的因素,主要包括煤层厚度、煤层瓦斯、生产规模等。巷道布置方式受煤层厚度及间距的影响,生产规模对采煤技术的选择影响较大。希望此次研究可以为煤矿开采设计提供一定的参考。
The selection of roadway layout ways and coal mining technology is crucial when mining underground in coal mines.In the mining design, it is necessary to select the appropriate roadway layout way and coal mining technology according to the geological conditions of the coal mine. This paper analyzed the roadway layout methods under different geological conditions,mainly including the roadway layout for multi-seam mining, the roadway layout for extra-thick coal seam mining and the roadway layout for thin coal seam mining, and discussed the factors considered when selecting coal mining technology, mainly including coal seam thickness, coal seam gas, production scale, etc. The way of roadway layout is influenced by the coal seam thickness and spacing, and the production scale has a greater influence on the selection of coal mining technology. It is hoped that the study can provide some reference for coal mining design.
