一.概述我们仿制的MXA-300型采煤机,在潞安矿务局王庄煤矿(采高3.5m)和西山矿务局官地煤矿(采高4.5m)通过了工业性试验;在王庄煤矿还开创了国产设备以单机、单工作面、单套人马年产百万吨煤炭的纪录;经上海煤矿机械研究所测试中心进行了型式试验,截割部、牵引部都一次通过了1000h的耐久性试验;1985年5月份在第三次全国煤炭科学技术大会上被评为科技进步一等奖。
I. Overview The MXA-300 shearer we copied passed the industrial test at Wangzhuang Coal Mine of Luan Mining Bureau (mining height 3.5m) and Guan Coal Mine of Xishan Mining Bureau (mining height 4.5m); at Wangzhuang Coal Mine has also created a record of domestic equipment with single machine and single face and a single set of people with an annual output of 1 million tons of coal. The type test was conducted by the Test Center of Shanghai Coal Mining Machinery Research Institute. The cutting department and the traction department all passed once 1000h durability test; in May 1985 at the Third National Coal Science and Technology Conference was named the first prize of scientific and technological progress.
