    CMJ2-27 FLAMEPROOF ROCK DRILLER FOR BLASTING HOLE IN THE UNDERGROUND COAL MINE

     

    CMJ27 Fully Hydraulic Jumbo is also known as rock driller, is designed for blasting hole drilling in a  roadway, especially in a rock roadway in the underground coal mine. It is widely used in the construction of coal mine, metal mine, hydropower station, railway, etc.

    The machine can not only drill holes in working face but also drill holes on roof, sideway, floor. The  drilling boom can rotary 360 degree, it can make the drilling in any direction and angle. This machine can also be used as a roof bolter.

    The max. hardness it can drill is 130Mpa, the drilling speed can reach 2 meters per minute.

    Besides coal mine, it can also used in  some other mines and projects for the blasting hole
