摘要
针对磁窑沟煤业使用连续采煤机与掘锚一体机单一施工大断面巷道掘进工艺后,材料配件投入费用高、人员投入多、空顶量大、受采动影响大,不利于管理顶板等问题,设计大断面切眼巷道施工,使用掘进一体机配套桥式转载机施工大断面多样化掘进工序,可根据地形、煤层及顶底板情况选择掘进工序和支护方案,化解其他掘进工艺所带来的诸多不利因素,改变原有的掘进工序,掘锚一体机施工大断面巷道掘进工序在条件允许的煤矿中,将具有广阔的推广价值。
Aiming at the problems of high investment in materials and accessories,high personnel investment,large amount of empty roof,large mining influence,and unfavorable management of roof in the single construction of large-section roadway by using continuous coal winning machine and intellectualized driving and anchor machine in Ciyaogou Coal Industry,the construction of large-section open-off cut roadway was designed.The diversified tunneling process of large-section was constructed by using the bridge loader equipped with the tunneling-anchoring machine.The tunneling process and support scheme could be selected according to the terrain,coal seam,roof and floor conditions.Many unfavorable factors brought by other tunneling processes could be solved,and the original tunneling process was changed.There was broad promotional value of the tunneling process with intellectualized driving and anchor machine in the coal mine where conditions permitted.
