苏联全苏矿床排水、特种采矿、矿山地质和矿山测量科学研究设计院对井下巷道中掘进天井用的排水钻孔的技术设备和工艺进行了长期的研究。地下钻进用的1M设备在苏联矿山企业中已使用多年。实践证明,其部件的组合和液压传动系统的运转状况是良好的。但在使用过程中查明:旋转器的结构不够可靠;下降和提升作业的机械化程度不够;在巷道中加固钻机、设备的安装和拆卸等作业的劳动量很大。用新式8型排水钻孔设备代替1M型,上述缺陷便可得到克服。根据对1M型钻机的分析和使用经 The Soviet Union Suchuang drainage, special mining, mining geology and mining surveying and science research and Design Institute of underground tunnels in tunneling drainage technology used for drilling equipment and technology for a long time. The 1M equipment for underground drilling has been used for many years in Soviet mining companies. Practice has proved that the combination of its components and hydraulic drive system operating conditions are good. However, during the process of application, it was found out that the structure of the rotator is not reliable enough, the degree of mechanization of descending and upgrading work is not enough, and there is a lot of labor to reinforce rigs and equipment in the roadway for installation and disassembly. With the new Type 8 drainage drilling equipment instead of 1M, the above defects can be overcome. According to the analysis and use of 1M drilling rig
