Mine coal using hand-held air drill, hand-held bolt rig, hand-held hydraulic coal drilling, hand-held emulsion drilling rig 
 Oxy-acetylene drill for wind moving coal drill, mainly used in mines, buildings, tunnels of the coal seam and soft rock drilling. Now mine has been gradually replaced by coal drill. Equipped with the drill pipe for coal drill pipe and twist drill rod, can be equipped with air leg. Light weight, use of coal drill. 
 Pneumatic coal drilling in coal mines and construction works, drilling on the seam, soft sandstone, shale and other handheld and Air-leg dual rotary pneumatic coal drilling, wet drilling and dry drilling can be used. Drilling range of 35-45mm 
 Pneumatic coal drill, hand-held drill can also be installed FT100 air leg gas leg coal drilling machine takes compressed air as power, with the bodies of planetary gear reducer, torque, safety explosion-proof, easy to operate, easy to repair characteristics, especially suitable for inflammable, explosive, humidity and other adverse work environment. Its use can greatly reduce the labor intensity and improve working conditions for workers, improve work efficiency.
