兖州矿业(集团)公司东滩煤矿在S150掘进机切眼扩宽中采用调头施工的新方法,其优越性相当明显。不但在施工的过程中消除了“替柱、回柱”以及回“大梁、柱腿”等环节,使得不安全因素减少、推进速度加快,而且避免了刮板输送机的反复安装。一般情况下,采用原先的施工工艺需要6天以后巷道才能够进入正常的扩宽,而在新的施工工艺条件下仅仅需要2天,缩短了工期4天;由于采面的准备时间缩短,更加便于设备的安装,工人的劳动强度也大为减轻。
The superiority of Yanzhou Mining (Group) Company, Dongtan Coal Mine, adopting a new method of turning the head in the widening of S150 heading machine’s cutting eyes is quite obvious. Not only eliminate the “” for the column, back column “and back ” girders, column legs "and other links in the construction process, making the insecurity reduce, promote the speed, and to avoid the repeated installation of the scraper conveyor . Under normal circumstances, using the original construction process takes 6 days before the tunnel can enter the normal expansion, and in the new construction conditions only need 2 days, shortened the duration of 4 days; due to the preparation of mining face shorter, more Easy to install the equipment, the labor intensity of workers is also greatly reduced.
