摘要
目前国内多数矿井岩巷掘进仍采用传统的岩巷炮掘施工工艺,平均月单进水平80 m左右,严重制约矿井的生产接续和安全高效生产。陕西彬长孟村矿业有限公司在大断面岩巷炮掘工作面采用了一套“CMJ2-35型矿用液压钻车+ZPY-40/20L煤矿用破碎装岩机+桥式转载机+CMM2-25型煤矿用液压锚杆钻车”的快掘系统装备。综合机械化的应用大幅度提升了岩巷炮眼施工、矸石破装运及锚杆索支护效率,降低了工人劳动强度,极大利于岩巷炮掘现场施工工艺的改进,矿井岩巷月单进水平由原来平均80 m提高到平均120 m,有效改善了矿井岩巷单进水平限制治灾工程进度的局面,为矿井及公司的岩巷快速掘进技术发展积累了经验。
At present,the rock roadway excavation of most domestic mines still adopts the traditional blasting driving technology,with an average monthly footage of about 80 m,which seriously restricts the production continuity and safe and efficient production of the mine.Mengcun Coal Mine adopts a set of rapid excavation system equipment of“CMJ 2-35 mine hydraulic drill truck+ZPY-40/20L mine crushing rock loader+bridge loader+CMM 2-25 mine hydraulic anchor drill truck”in the blasting face of large section rock roadway.The application of comprehensive mechanization has greatly improved the efficiency of blasthole construction,waste rock breaking and loading and anchor cable support in rock roadway,reduced the labor intensity of workers,and greatly improved the blast excavation construction technology in rock roadway.At the same time,the monthly footage of the mine rock roadway has been increased from the original average 80 m to the average 120 m,which effectively improves the situation that the blast excavation of mine rock roadway restricts the progress of the disaster control project,and accumulates experience for the development of the mine rock roadway rapid tunneling technology.
