■ Application Scope
ZDY3500L(A) explosion-proof crawler underground drilling rig is on exhibition. Both azimuth angle and pitch angle can be adjusted at a range of -90°～90° which can enhance the adaptability and drill boreholes in a wide range of angle. It has a narrow width of 0.95m which is quite suitable to be operated and transported in narrow underground roadway or tunnel.
The rig has capacity to drill as deep as 350m and is widely used for gas drainage, water detect and discharge, geological exploration and engineering borehole drilling.
