克里沃罗格矿业学院在克里沃罗格矿区“列宁鲁大”托拉斯地下矿山中研究了斜底柱在房式采矿法中的应用效果。图1.采准、切割巷道单位长度与矿体厚度的关系:1.采用平底柱;2.采用斜底柱(计算数据);3.采用斜底柱(回采柯明特尔那矿务局“布尔什维克”矿井618米水平的74号和100号矿块所得的实际数据)在三十多个已回采的矿块中,对平底柱内采准和切割巷道长度计算的结果,得出了这些巷道的单位长度(每千吨矿块储量所摊的采准
The Krievoglu Institute of Mining has studied the application of sloping pillars in room mining in the Krieivoglu Mine “Leningrad” underground mine. Figure 1. Admission, cutting the length of the tunnel unit and the relationship between ore body thickness: 1. The use of flat-bottomed; 2. The use of inclined bottom column (calculation data); 3. The use of inclined bottom column Actual data obtained from No. 74 and No. 100 ore blocks at the level of 618 m at the Bolshevik Mine) The calculation of the length of reclamation and cutting tunnels within the pillars in more than 30 mined mines resulted in The length of each unit of these tunnels (the allowance for each thousand tons of ore reserves
