用汽车斜坡道开拓矿床下部水平可缩短采准期。优选汽车斜坡道的位置,少掘一条或几条竖井,缩短主水平巷道的长度,可减少开拓工程的基建投资。某企业1号矿开采总矿化面积为3×4公里的一系列矿体,现以这些矿体侧翼下部水平的开拓为例进行研究。该矿田用 C_1和 C_2竖井、几条通风井(至Г_1水平)和 C_3、C_4盲井并拓(见图)。矿田中部基本储量采完后,需要开拓远
Using car ramps to open up the lower part of the deposit can shorten the mining period. Optimizing the location of car ramps, excavating one or a few shafts less and shortening the length of the main horizontal roadway will reduce the capital investment for pioneering works. A number of enterprises mining a total mineralization area of 3 × 4 km ore body, now the lower part of the flank of these ore exploration as an example. The mine uses C_1 and C_2 vertical shafts, several ventilation shafts (up to Γ_1 level) and C_3, C_4 blind wells and extension (see figure). After mining the basic reserves in the central part of the ore field, it needs to explore far
