按照煤矿设计规范,设计生产能力为3～30万吨/年的矿井,被认定为小型矿井。这些煤矿,为了查明井下地质构造、勘查水文地质情况和探放水、排放和抽放瓦斯、事故应急救援等,都不可缺少坑道钻机。因此小型煤矿坑道钻机的选型和应用值得深入研究。 According to the design specifications of coal mines, the designed production capacity of 3 to 300,000 tons / year of the mine, was identified as a small mine. These coal mines are indispensable for tunneling geological structures, hydrogeological exploration and exploration and drainage, drainage and gas drainage, emergency rescue and other accidents. Therefore, small coal mine tunnel rig selection and application deserves further study.
