摘要
结合杜儿坪矿南翼中组煤皮带巷掘进实例,分析了掘进巷道复杂地质情况,从截割工艺、平行施工、支护工艺以及循环作业等方面巷掘进工艺加以优化,确保南翼中组煤皮带巷掘进施工能够安全、高效进行。
Combined with example of the middle coal seam belt tunneling in the south wing of Duerping Colliery, the paper analyzes complex geological conditions of roadway, optimizes excavation process from aspects of cutting process, parallel construction, support technology and cycle operation, which ensures safe and efficient construction of the middle coal seam belt tunneling in the south wing.
