1958年建成投产的年产120万吨的《红湾》煤矿,在1988年将庆祝建矿三十周年。今天计划采煤任务实际上已经翻番,年产约243万吨。这个成绩的取得是由于从一开始就采取了生产过程综合机械化的方针。在第八个五年计划中期已全部使用KM—87型综合机械化设备采煤,而矿井用掘进机掘进的机械化程度已超过90％。 从那时起到目前为止,矿井煤产量稳定增长。应当看到,在整个时期矿井工作面的 The 1,200,000-ton “Hongwan” coal mine, completed and put into operation in 1958, will celebrate the thirtieth anniversary of its founding in 1988. Today’s planned coal mining mission has actually doubled, with an annual output of about 2.43 million tons. The result of this achievement is that the principle of comprehensive mechanization of the production process has been taken from the very beginning. In the middle of the Eighth Five-Year Plan, all the KM-87 integrated mechanized equipment was used for coal mining, while mine shaft boring machines were mechanized by more than 90%. Since then, coal mine production has been steadily increasing. It should be noted that during the entire period of mine face
