CMS1-6500/75D Coal mine deep hole directional drilling jumbo adopts a split structure and is suitable for motor directional drilling and grouting at the bottom of the bore rotary drilling, and other construction technology, can be used in the coal mine gas drainage drilling construction, can also be used for downhole drilling drainage, geological structure and coal seam thickness detection, coal seam affusion, roof and floor grouting etc. All kinds of high precision of the directional drilling construction. Supporting equipment: directional drill + screw motor + measuring pipe + magnetic drill pipe + cable drill pipe + explosion-proof computer.
Product Features
Stable, convenient and efficient
The drilling jumbo adopts horizontal layout, with upper and lower jacking support cylinders arranged at four corners, and front jacking cylinder arranged at the front of the guide rail to achieve fast support drilling and steady drilling.
Track presets, real-time display
Multi-directional branch drilling, preset drilling trajectory; high-precision measurement while drilling system, real-time display of main parameters such as drilling inclination, azimuth, tool face angle, and precise control of drilling direction.
High power and high drilling efficiency
The stepless variable motor drives rotary drilling, and the high-torque bottom-hole motor directional drilling has high drilling efficiency. Energy-saving and high-efficiency load-sensing system and pilot proportional control system can precisely control the feed speed and rotation speed.
Split structure, flexible and convenient
The whole machine is composed of a main car and a pump car, and the two cars walk independently, and the drilling field is flexible and convenient.
Wide range of applications
It is suitable for gas drainage drilling, exploration and drainage drilling, geological exploration drilling hole, coal seam water injection drilling hole and various engineering drilling holes in this coal seam, high position and floor penetration layer.
