库茨内特斯克的塔什塔戈尔矿的矿房回采法有一定缺点,主要是矿块分期回采(先采矿房后采矿柱)。这样矿块的生产率低(15000～18000吨/月),矿块准备的劳动费用高,采准比为4.6米/1000吨,费用为0.7卢布/吨。因此,这个矿山改用一种振动连续放矿的分段回采法。这个方法的矿体中段高40～80米,各中段的盘区宽20～27米,长为矿体厚度。在盘区之间不留矿柱,矿石回采在一连续工作面沿走向进行。各中段开凿两条脉外运输巷道,约隔
There is a certain shortcoming in the mining method of Tashtagol Mine in Khortztesk, mainly because of the staged mining of the ore blocks (the mining pillar is the first post-mining house). The productivity of such nuggets is low (15,000 to 18,000 t / month) and labor costs for nuggets are high with an O & M ratio of 4.6 m / 1000 t at a cost of 0.7 rubles / tonne. Therefore, the mine switched to a vibrating continuous mining sub-mining method. The middle of the ore body of this method is 40 to 80 meters in height, and the panels in each middle section are 20 to 27 meters wide with the thickness of the orebody. No pillars remain between the panels, and the mining of the ore proceeds along a continuous face. The middle section of two veins cut tunnels, about every interval
