(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
Moreover, environmental concerns have prompted innovations in downhole equipment aimed at minimizing ecological impact. Biodegradable drilling fluids and closed-loop systems are becoming more common to reduce waste and ensure effective environmental protection during drilling operations.
The durability and effectiveness of jaw plates significantly impact the overall performance of the jaw crusher. When materials are fed into the crusher, they are subjected to immense pressure as the movable jaw compresses them against the stationary jaw. The shape, design, and material composition of the jaw plates are critical in determining the crushing efficiency. High-quality jaw plates contribute to the longevity of the crusher, ensuring consistent performance over time.
Conclusion
(3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.

The factor 1714 is a constant used to convert the product of flow rate and pressure into horsepower.
3. Open-air drilling rig: according to the different working mechanism of crushing ore and rock, it is divided into steel rope percussion drill, drilling rig, cone drill and rotary drill. Because of low efficiency, the steel rope percussion drill has been gradually replaced by other drilling RIGS. The drill pipe drives the pneumatic impactor and the drill bit to rotate together, and the piston of the pneumatic impactor is used to impact the drill bit to break the ore and rock, which is usually used in small and medium-sized mines to drill holes with a diameter of 80 to 250 mm.
