[0002] The repair of used pneumatic anchor bolters is an increasing problem. However, due to a lack of testing for rated torque, speed, and thrust, the repair quality cannot be verified, resulting in poor repair quality. Newly repaired pneumatic anchor bolters often experience insufficient torque, low speed, and substandard thrust in coal mines. Repaired anchor bolters often remain inoperable underground for a short time or become unusable, requiring them to be brought back to the surface for repair. Production scheduling meetings frequently raise concerns about the quality of anchor bolt repairs.
