Crawler rigs are mainly used for long in-seam horizontal drilling operation of gas drainage boreholes and boreholes in soft coal seams in underground coal mines. It can use both ordinary outer planar drill rods for conventional drilling and spiral drill rods as well, mainly for drilling gas drainage boreholes in a coal seam and its adjacent seams and boreholes in soft coal seam.
