为了迅速提高井下平巷机械化的掘进水平,加速解决采掘落后的矛盾,湖南省冶金局从今年三月以来,积极组织了重点有色矿山机械化掘进操作技术表演赛。参加比赛的重点有色矿山有15个,先后在水口山铅锌矿、锡矿山矿和汝城钨矿三个赛区进行了初赛。在每个分区赛中获得前两名的掘进队,于1979年7月5日～9日在瑶岗仙钨矿进行了决赛。由于各矿加强了机械化掘进队的建设和设备的改进,赛前又进行了积极的准备,因此,在这次表演赛中表现出操作灵活、技术精湛、互相配合、基
In order to rapidly raise the tunneling mechanization level and speed up the solution to the contradiction of mining outdated, Hunan Metallurgical Bureau has actively organized the technical exhibition of key non-ferrous mining mechanized tunneling operations since March this year. There were 15 key non-ferrous mines participating in the competition, having held the first race in the three competition zones of Shukou Mountain lead-zinc mine, tin mine and Rucheng tungsten mine successively. The top two tunneling teams in each division race were finalized at the Yao Gang cents tungsten mine from July 5 to 9, 1979. As the various mines strengthened the construction of mechanized driving teams and the improvement of equipment, they also made active preparations before the race. Therefore, they demonstrated flexibility in operation, exquisite workmanship and complementarity
