倾斜岩巷爆破掘进方案对比及施工安全措施

Comparison of Blasting Excavation Schemes and Construction Safety Measures in Inclined Rock Roadway

以凤凰山矿一五三盘区回风斜巷爆破掘进施工为例,通过对比上山掘进和下山掘进的优缺点,选择采取上山掘进。制定上山掘进时克服人员物料上下困难、喷射混凝土及煤矸运送距离过长、穿过煤层时顶板补强支护等问题的应对措施,确保倾斜岩巷上山掘进施工安全、高效。

Taking the blasting driving construction of the return inclined lane in the No.153 panel area of Fenghuangshan Mine as an example,the driving up the mountain is selected by comparing the advantages and disadvantages of driving up and driving down the mountain.In order to ensure the safety and efficiency of the uphill driving construction of the inclined rock roadway,countermeasures should be made to overcome the difficulties of personnel and materials,the long distance of shotcreting and coal gangue transportation,and the roof reinforcement and support when passing through the coal seam.
