Abstract

Reasonable production capacity is related to the economic benefits of an open-pit coal mine. This study analyzes the relationship between the working face length, the annual advancing speed and the production capacity. It constructs a production capacity function relationship model. Take the Baorixile open-pit coal mine as an example. The remaining unmined parts are divided into four regions, and the range of production capacity in each region is analyzed by the established model and the determined respectively. On this basis, three mining district division plans are proposed. By analyzing and comparing the stripping ratio, mining life of the district, fault influence, difficulty of transition connection in the mining districts, the convenience of transportation system layout and other indexes of each plan, Plan 3 is determined to be the optimal plan. The production capacity planning results of each mining district in this plan are as follows: the production capacity of the 3rd mining district is 30-35 Mt/a; the production capacity of the 4th mining district in Region 1 is 20-31 Mt/a, and the production capacity in Region 2 is 24-33 Mt/a; the production capacity of the 5th mining district is 20-27 Mt/a.

摘要

合理的生产能力与露天煤矿的经济效益有关。本研究分析了工作面长度、年推进速度和生产能力之间的关系。构建了生产能力函数关系模型。以宝利西勒露天煤矿为例，将剩余未采部分分为四个区域，通过建立的模型和确定的模型分别分析和确定各区域的产能范围。在此基础上，提出了三种采矿分区方案。通过分析和比较各方案的剥离比、矿区开采寿命、断层影响、采矿过渡连接难度、运输系统布置便利性等指标，确定方案 3 为最优方案。该方案各矿区的产能规划结果如下：第 3 矿区的产能为 30-35Mt/a；第 1 区第 4 矿区的产能为 20-31Mt/a，第 2 区的产能为 24-33Mt/a；第 5 矿区的产能为 20-27Mt/a。
