深槽漏斗剥离适用于阶段高度为20～30米的工作面上剥离表层及堆积层岩石,也可以用于贫矿带的采矿工作面上.深槽漏斗剥离的操作方法和步骤如下: 1.在大阶段工作面上,先选择适当位置,利用三面原岩架设漏斗.其规格高1.8～2米,宽1.5～1.8米.长1.8～2.2米. 2.漏斗架设好以后,用碎石或泥土充填漏斗底 The deep groove hopper stripping is suitable for stripping the surface layer and the accumulating layer of rock on the work surface with a stage height of 20-30 meters, and it can also be used on the mining face of the lean ore belt. The operation method and steps of the deep groove hopper exfoliation are as follows: On the large-scale working surface, first select the appropriate location and use three sides of the original rock to set up the funnel. Its specifications are 1.8 to 2 meters high, 1.5 to 1.8 meters wide and 1.8 to 2.2 meters long. 2. After the hopper is set up, use gravel or Soil filling funnel
