    1.Brief introductions of KHYD75 electric rock drilling rig for coal mine

    KHYD75 is a electric rock drilling rig for coal mines. It is a tool for drilling rock burst holes. It is used in the operation of mine road way driving, road construction, water conservancy construction, metallurgical mining and stone square engineering, and can also drill water hole, water probe hole and gas hole in coal seam.

    (1)electric rock drilling rig can be combined with drilling stand, and can be horizontally forward or inclined upward and downward.

    (2)In order to prolong the service life of the drill bit and improve the working conditions of the operator, it can be used for mixing the drill hole water to discharge the powder or also using the spiral vane drill pipe to drill and dry powder discharge.
