ZDY-1250 coal mine hydraulic drilling rig, hydraulic drilling rig wholesale Scope???? The drilling rig is mainly used for coal mine gas drainage (row) put holes, grouting fire hole, coal injection holes, anti-sudden relief hole , holes and other engineering geological exploration holes. Suitable for rock solid factor f ≤ 10 various coal, rock. Azimuth and inclination within the scope of any of the drilling rig can be specified in the basic parameters of the table. ZDY-1250 coal mine hydraulic drilling rig?? Its sub-frame and stand upright drill frame two forms, according to the level of the roadway and use of coal mine choose different drill frame. ? The rig is equipped with a high voltage generator and a selection of high-pressure water seal can drill for coal seam permeability low kerf, thereby improving the efficiency of gas drainage and shortened drainage time. The rig uses hydraulic drive mechanism, a large drilling capacity, fast, easy to operate, reliable, easy to install and so moving.
