Abstract: The all hydraulic rig mainly adopts detachable structure that is used in gas drainage in coal mine gallery.It will take time and need great effort to move the rig and be inefficiency in the drilling construction.The research and manufacture of the track-mounted rig will solve the problems.The research,manufacture and application of four kinds of new gallery track-mounted rig are introduced in this paper.The track-mounted rigs are convenient for moving in underground road and easy for dip adjusting,sage for fixing.The parameter of rig is reliable and is of high capacity for drilling accident solving.The hydraulic system adopts multi-pump system which is easy for control every operation parametevs.The load sensitive technique is adopted,which can control remote operation to meet the requirements of underground drilling.
