基于破碎站滞后移设对内排空间的影响,建立了破碎站滞后移设减少内排空间及增加外排土费用的计算模型.由于巷道运煤系统的投资及运营具有长期性的特点,因此需要考虑运输系统在整个服务年限内的总费用.提出了采用动态折现法对移设总费用进行分析计算.结果表明,动态总支出费用随破碎站及端帮平巷移设步距的增加呈先减少后增加的变化趋势,由此确定安家岭露天矿4煤破碎站的合理移设步距为120m;4煤和9,11煤的端帮平巷合理移设步距分别为240m和180m.
Based on the influence of the lag transfer of the crushing station on the internal discharge space, a calculation model of the lag transfer of the crushing station to reduce the internal discharge space and increase the cost of the external drainage is established.Because the investment and operation of the coal transportation system have long-term characteristics It is necessary to consider the total cost of the transportation system in the entire service life.This paper presents a dynamic discounted method to analyze and calculate the total cost of the transfer.The results show that the total dynamic expenditure with the increase of the crushing station and end to lane The first step is to reduce and then increase the trend of change, thus determining the reasonable displacement step of 4 coal crushing stations in Anjialing open-pit coal mine is 120m; 180m.
