In order to extract gas efficiently in soft outburst coal seam with belt haulage roadway, a ZDY2800LG full hydraulic drilling rig with high drilling rate, cross-belt construction ability and strong adaptability of technology was developed. The whole process of industrial test of drilling machine is introduced in detail through three stages of formation groping, breakthrough seeking and efficient drilling.
