论煤矿岩巷快速掘进技术

Discussion on Rapid Excavation Technology of Coal Mine Rock Roadway

结合新井矿岩巷的快速掘进技术,研究了采用液压钻车配套新型侧卸式装岩机的岩巷机械化掘进作业线、中深孔光面爆破和湿式喷浆系统在岩巷掘进中的关键技术,进一步提出了矿井岩巷掘进中存在的问题和解决的方法。研究得出,这套岩巷综合掘进技术,大大降低了工人劳动强度和材料消耗,减少了巷道超欠挖,改善了作业环境,初步实现了岩巷高效安全掘进。

With the rapid excavation technology of rock roadway of new wells, this paper analyzes the hydraulicunloading loader vehicle matching model of lateral drilling rock mechanized excavation line, the key technology in rockroadway in deep hole smooth blasting and wet spraying system, further puts forward the existing problems in mine rockroadway and the solution method, practice shows that this comprehensive rock drivage technology, greatly reduce thelabor intensity of the workers and the consumption of materials, reduces the tunnel overbreak, improve the workingenvironment, realized the efficient and safe excavation in rock roadway.
