乌拉尔石棉公司现正在南、中、北三个大型露天矿进行矿建工程。三个露天矿的矿岩总生产能力达2亿 t/a。目前,南矿和中矿的深度分别达到230m 和270m,矿床开采的设计深度则为680m。矿建工程在各矿采场的东帮和西帮上进行,采场境界内大部分工程均未达到最终位置,仅个别区段处于长期停工状态。三个矿分别采用铁路运输和汽车-铁路联合运输,其中铁路运输承担主要运量。随着工作帮的开采,各矿的配车站必须周期移设,从而导致铁路运输作业区下降速度滞后,降低了采矿强度,延长了汽车运
Ural asbestos company is now South, China and North three large-scale open-pit mine construction projects. Three open-pit mines rock production capacity of 200 million t / a. At present, the depths of South Mine and Middle Mine reach 230m and 270m, respectively. The designed depth of the deposit is 680m. The mining construction works are carried out on the east and west sides of the various stopes. Most of the works in the stope have not reached the final position and only a few sections are in a long-term shutdown state. The three mines use rail transportation and automobile-rail joint transportation respectively, of which the railway transportation undertakes the major traffic volume. With the help of mining, the distribution stations of various mines must be relocated cyclically, resulting in the slowdown of the railway transportation operation area, the decrease of mining intensity and the prolongation of automobile transportation
