ZQJ-150 / 1.9 Pneumatic Pillar Drilling Rig (formerly ZFG-100)
ZQJ-150 / 1.9 Pneumatic Pillar Drilling Rig (formerly ZFG-100) uses compressed air as the power, the air supply is greater than 6m3 / min, and the air supply pressure is 0.4 ~ 0.6Mpa. Compressed air is divided into 3 channels by the air divider, namely the rotary gas path, the feed gas path, and the slag discharge gas path. It has high safety and avoids potential safety hazards caused by the use of electrical appliances. It is mainly used in coal mines with coal and gas outburst and explosion hazards. It can also be used to drill gas drainage holes, coal seam water injection holes, fire extinguishing grouting holes, and other general coal mines.
