大型储煤厂煤炭装车系统优化研究 -

基于铁道部从2010年9月开始治理铁路货物装运超偏载,大秦铁路线担负山西、内蒙的煤炭外运任务,运力紧张,铁路多次提速的情况,铁路部门对平朔矿区煤炭装车速度、装运超偏载,提出了更高的要求;为确保不超偏载,铁路部门一般要求减吨装车,导致企业效益下降。通过分析研究输送带运量、装载物料性质、操作技术、装车系统工艺流程,介绍和探讨了提高装车速度、减少超偏载频次、减少亏吨的方法和途径。结果表明:平朔矿区装车系统亏吨由1.2%降到0.8%,超偏载次数明显减少,装车时间控制在2.5 h以内。 Daqin railway undertakes the task of transporting coal from Shanxi Province,Inner Mongolia Province to other areas in China.There are lots of hidden dangers due to long-term overloaded transporting and behindhand devices which can't meet the speed-raising demand.Eliminating overload and unbalanced load means less coal loading amount,which directly influences the benefits of coal company.Through the analysis of conveying belt load,characteristics of carried materials,operation techniques and loading technological process,provide methods improving loading speed,reducing the frequency of overload and unbalanced load and shortfall.The results show that the shortfall decreases from 1.2 percent to 0.8 percent,the frequency of overload and unbalanced load sharply reduces,the loading time is less than 2.5 hour
