大断面全岩巷道施工工艺设计

Design of Large Section Whole Rock Roadway Construction Technology

煤矿巷道掘进施工过程需依据巷道地质条件,诸如围岩及煤层情况、岩层结构、瓦斯等有害气体、水文地质情况等,对巷道布置、掘进工艺、支护工艺、运输系统、通风系统、供电系统等予以合理设计,才能保证掘进巷道施工工艺的合理性和巷道掘进施工的质量。研究分析了某煤矿巷道的施工工艺,并进行相关设计方法的剖析,为以后的研究及改进工作提供有效的理论指导依据,同时提出尚需继续深入研究的方向。

In order to ensure the rationality of construction technology and the quality of tunneling construction, the construction process of coal mine roadway excavation should be designed based on the geological conditions of roadway, such as surrounding rock and coal seam conditions, rock structure, harmful gases and hydrogeologic conditions, to rationally design roadway layout, excavation technology, support technology, transportation system, ventilation system and power supply system. The construction technology of a coal mine roadway has been studied and analyzed, and the relevant design methods have been analyzed, which can provide an effective theoretical basis for future research and improvement. At the same time, the research direction which need further study have been put forward.
