1. Greater Efficiency DTH drilling significantly reduces drilling time when compared to rotary methods. The direct impact of the hammer allows for faster penetration rates, enabling operators to cover more ground in shorter periods. This efficiency is especially critical in industries where time equates to money.
3. Flow Rate and Pressure Determine the required flow rate and the pressure at which the slurry needs to be transported. This will influence the type of pump chosen, as different pumps have specific performance curves.
1. Slurry Characteristics The composition, concentration, and size of solids in the slurry must be thoroughly analyzed. A high solid concentration requires a pump that can withstand wear and manage viscosity effectively.
2. Percussive Drills These drills utilize a hammering action to break rock apart, making them effective for hard materials. They are often used for both surface and underground mining operations.
When the wind force is greater than level 6 during operation, the pile driver should stop the operation, and the oil cylinder should be used as an auxiliary support. If necessary, a wind rope should be added for fixing.When the crawler is piled, avoid the collision between the drill pipe reinforcement cage and other columns.
