本文介绍了在同样条件下横巷扒矿与平巷扒矿相比矿块出矿效率的变化规律。就提高扒矿效率的因素而言,确定了横巷扒矿方案的合理使用范围,这在一定条件下,可显著提高分段崩落法的开采效率,在克里沃罗格矿区这种采矿方法方案比重已达64%。回采工作面电耙出矿效率Π_c 取决于电耙设备的技术生产能力Π_M 和二次破碎及溜
In this paper, the changing rules of ore-discharging efficiency of horizontal-lane paving mines and flat-lane paving mines under the same conditions are introduced. In terms of improving the efficiency of grilling, the reasonable application scope of the cross-lane grilling project is determined. Under certain conditions, the mining efficiency of the sub-caving method can be remarkably improved. This mining method The proportion of programs has reached 64%. Mining face mining efficiency Π_c electric rake depends on the technical capacity of electric rake equipment Π_M and secondary crushing and slippery
