保持采区采准巷道的稳定性,是提高井下采煤技术经济效果的主要问题之一。选择保持稳定性的方法和手段,应该通过分析煤矿地质和开采工艺因素,并以它作基础进行分类,该分类不仅应反映现状和研究方法,而且指出其科学发展的一般方向。分类的先进性不仅要求包括所有工艺系统的可行方案,而且能预见长远的技术方案, 现有的保持巷道(?)定性的分类方法,没有全部包括回采工作面和采(?)巷道在空间位置上的技术因素,和关于(?)层的埋藏因 Maintaining the stability of the roadway adopted by the mining area is one of the major problems in improving the economic results of underground coal mining technology. The method and means of choosing stability should be classified based on the analysis of coal geological and mining process factors. The classification should not only reflect the status quo and research methods, but also point out the general direction of its scientific development. The advanced nature of the classification requires not only viable options that include all process systems, but also predictable long-term technical solutions. Existing classification methods that maintain the qualitative characterization of the roadway (†), not all of which include the mining face and the roadway in the spatial location On the technical factors, and on the (?)
