MQT type pneumatic bolt drill
Main use
MQT type pneumatic bolt drill is mainly used for coal mine rock hard ≤f10 coal roadway, rock roadway bolt, anchor cable support drilling, and can stir and install resin bolt, anchor cable, for the bolt with damping nut, can be directly tightened nut during mixing, to achieve the bolt mixing, installation once completed, and meet the requirements of the initial anchor preload.
Main feature
- The degree of engineering plastic material, light weight, easy to operate.
- The use of large size motor for power, power weight ratio is larger, longer service life.
- The propulsion part adopts new fiberglass cylinder, which is safe and explosion-proof, lightweight and flexible.
- The water valve using technology can adapt to the ultra-high surface static pressure water in coal mines.

1. What is the primary application of the MQT type pneumatic bolt drill?
The MQT type pneumatic bolt drill is mainly used in coal mines for drilling rock roadways and coal roadways with a rock hardness rating of ≤f10. It is suitable for bolt and anchor cable support drilling, as well as resin bolt mixing and installation.
2. How does the drill achieve one-time installation of bolts?
For bolts equipped with a damping nut, the nut can be directly tightened during the mixing process. This design enables the mixing and installation of the bolt to be completed in a single operation, fulfilling the initial anchor preload requirements.
3. What makes the propulsion design of this drilling rig safe?
The propulsion mechanism utilizes a new fiberglass cylinder. This material construction is lightweight, highly flexible, safe, and explosion-proof, making it ideal for the hazardous environments of coal mines.
4. Can this machine handle high water pressure conditions in mines?
Yes. The drill incorporates advanced water valve technology that is designed to adapt to the ultra-high static pressure water typically encountered in underground coal mine roadways.
5. What are the key differences between the MQT110, MQT120, and MQT130 models?
The models differ primarily in performance specs: the MQT110 has a rated torque of 110 N.m and weighs 48 kg; the MQT120 delivers 120 N.m torque and weighs 52 kg; and the MQT130 delivers the highest performance with 130 N.m torque, a max power of ≥3.0 KW, and a weight of 54 kg.
