锡林郭勒盟地区是我国近年新开发的煤炭基地之一,五间房矿区是该区域内的第一座大规模开发的井工矿开发区,该区主要开采煤层为白垩系褐煤。由于成煤年代较晚,地层沉积条件较差导致工程地质条件差,另外较厚的第三系地层也是矿井巷道支护的一个挑战。本文根据该区域工程地质情况,以该矿副斜井为例对巷道支护方式选择进行了分析,提出了可行方案,对该区域类似矿井建设有借鉴意义。
The Xilin Gol League is one of the newly developed coal bases in China in recent years. The Wufangfang Mine is the first large-scale well-developed industrial zone in the region where the main coal seam is chalky lignite. Due to the late coal formation, poor formation deposition conditions lead to poor engineering geological conditions, and thicker Tertiary formation is also a mine roadway support challenges. Based on the engineering geological conditions in this area, taking the sub-inclined shaft of the mine as an example, this paper analyzes the choice of roadway support ways and puts forward feasible solutions, which can be used for reference for similar mine construction in this area.
