大同矿务局自1974年12月第一套综采设备投入运行以来,目前在全局14个生产矿井的124个采煤队中已有35个综采队,1988年底综采机械化产量已占全局回采总产量的57.17％,其中同家梁矿综采一队已连续8年取得创年产量百万吨的好成绩。为了使综采机械化能在大同矿务局取得更好的效益,在总结这15年综采生产实践经验的同时,从中找出或发现一些问题,以便引起注意和改进。一、几项指标反映出的问题 1.综采机械与回采产量图1中的三条曲线。分别表示回采产量
Datong Mining Bureau since December 1974 the first set of mining equipment has been put into operation, the current 14 production mines in the 124 coal mining team has 35 mining team, mechanized production by the end of 1988 has accounted for the overall 57.17% of the total output was recovered, of which the first team of the same-parent fully mechanized coal mining company has achieved a good result of one million tons of annual output for eight consecutive years. In order to make the mechanization of fully mechanized mining in Datong Mining Bureau to achieve better efficiency, summarize the 15 years of experience in fully mechanized production practice at the same time, find out or find some problems in order to attract attention and improvement. First, the problems reflected by several indicators 1. Fully mechanized mining and recovery of production in Figure 1 of the three curves. Respectively, said the mining output
