目前是按国家采矿设计院制定的暂行规程计算露天矿线路系统的通过能力和运送能力。这一文件规定利用推定方法计算露天矿铁路运输区间的分界点(车站、会让站、信号所)的通过能力及运送能力,并对进行计算所必需的系数和完成各工序的时间定额做了定量规定。由于列车在露天采场-选厂-排土场系统中运行具有随机性质,并服从于大量服务理论的原则,复杂线路系统的通过能力和运送能力的计算方法不能反映露天矿矿岩运输工 At present, the passing capacity and delivery capacity of the opencast mine line system are calculated according to the provisional rules formulated by the State Mining Design Institute. This document stipulates the use of a presumption method to calculate the passing capacity and carrying capacity of the demarcation points (stations, stations, signaling stations) of the open-pit railroad transport section and makes the necessary coefficients for the calculation and the time quotas for completing the processes Quantitative regulations. Because of the stochastic nature of trains operating in an open pit-plant-dump system and subject to the principle of mass service theory, the calculation of the capacity and carrying capacity of complex line systems can not reflect the behavior of open pit miners
