我省从一九七七年开始试验推广高档普采配套设备,目前已发展到八套,在五个矿的六个工作面中使用。实践证明,高档普采有很大的优越性,与综采比,具有投资少、见效快、易掌握、安装撤除方便、适应性强等特点;与MLQ_1—80型普采比,具有产量高、效率高、成本低、安全好等优点。它的推广应用,对于改变我省目前一般采煤机械化的生产技术面貌和各项经济指标,促进煤炭生产发展,必将发挥越来越大的作用。
Since 1977, our province has experimented with and popularized high-grade general-purpose mining and auxiliary equipment. At present, it has developed into eight sets and is used in six work surfaces in five mines. Practice has proved that high-grade general mining has great advantages, and comprehensive mining ratio, with less investment, quick, easy to grasp, easy installation and removal, adaptability and other characteristics; and MLQ_1-80 type of general mining than with high yield , High efficiency, low cost, good safety and so on. Its popularization and application will play more and more important roles in changing the general technical aspects of coal mining mechanization and various economic indicators and promoting the development of coal production in our province.
