一、使用概况我矿原设计为年产45万吨,79年实际产量达到了80万吨,全井下共使用23部皮带运输机和47台刮板运输机,从采煤工作面到装载峒室,组成一条龙运输系统。 68年投产初期,各台运输机均为单开,随着生产发展,设备增多,人员不足,迫使我们不得不采用集中控制。70年以来我们先后坚持使用了油压速度集中控制,1JJ—10 First, the use of the profile I mine designed for an annual output of 450,000 tons, the actual production in 79 years reached 800,000 tons, a total of 23 underground belt conveyors and scraper transport aircraft 47, from the coal face to the loading room, Form a one-stop transport system. In the early years of production, 68 years ago, all the transport planes were opened. With the development of production, more equipment and fewer staff forced us to adopt centralized control. For 70 years we have insisted on the use of hydraulic speed centralized control, 1JJ-10
