Description of Pneumatic Roof Bolter Hand-held
A roof bolter is a hydraulically driven miner-mounted bolting rig used to install rock bolts in mines, tunnels, underground power plants, and storage facilities.
Roof bolting is also a common application in underground coal mines for securing mine roofs to be self-supportive. It is extremely dangerous as an occupation, accounting for nearly 56 percent of injuries in underground coal mining operations.
Bolt drilling rigs are also called anchoring rigs in some places, and they are drilling tools in coal mine roadway bolt support work. It has outstanding advantages in improving the supporting effect, reducing support costs, accelerating the speed of roadway formation, reducing auxiliary transportation, reducing labor intensity, and increasing the utilization rate of roadway sections.
Parameter of Pneumatic Roof Bolter Hand-held
The use of roof bolting rigs requires outrigger-type bolting rigs: MQT series pneumatic bolting rigs can be selected. This type is suitable for roof anchors of various coal roadways, semi-coal and rock roadways with roof hardness ≤ f10 During operation, it is equipped with B19/B22 hexagonal kelly, drill bit, and anchor rod (cable) agitator to complete the roof anchoring operation. It is anchoring equipment that integrates drilling, mixing, and fixing. Pneumatic bolting rig has high speed, high power, compact structure, new exhaust structure and outrigger sealing design, outrigger lifting fast, large thrust, 30% increase in work efficiency, labyrinth silencing design, the exhaust does not freeze, Stable performance and good adaptability.
