(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor.

4. Reduced Costs Despite potentially higher upfront equipment costs, DTH drilling can lead to substantial savings over time. The efficiency and speed of the method mean lower labor costs and quicker project completion times. Furthermore, the reduced need for extensive maintenance and downtime enhances overall productivity.

Furthermore, the low pressure leads to less shielding from cosmic radiation and solar winds compared to Earth, where the thicker atmosphere and magnetic field offer some degree of protection. This raises questions about the potential for life on Mars and poses challenges for future manned missions, as astronauts will need adequate shielding from these harmful rays.

In the mining sector, the tungsten crusher contributes to the extraction process by preparing ore for downstream processing. Properly crushed tungsten ore can be more easily concentrated through methods such as gravity separation or flotation. This is vital because impurities in ore can hinder the quality and performance of the final tungsten products.

1.Downhole drilling machine: When drilling a downhole gun hole with a aperture less than 150 mm, in addition to the application of a rock drill, it can also be used to drill a small diameter of 80 ~ 150 mm. When drilling a gun hole with a diameter of less than 70 mm in coal or softer mineral rock, it is generally used to drill or air drill, driven by a motor (or air motor) to drill the drill pipe, and the rock (coal) chips drilled out are discharged through the spiral groove on the drill pipe.

In the world of drilling operations, particularly in oil and gas exploration, the mud pump plays a crucial role. A mud pump is a vital piece of equipment that circulates drilling fluid (commonly referred to as mud) from the surface to the drill bit and back up to the surface. This fluid serves multiple functions it cools and lubricates the drill bit, removes cuttings from the wellbore, and maintains the necessary pressure to prevent the influx of formations fluids. Therefore, accurately calculating the performance of a mud pump is essential for efficiency and safety in drilling operations.

In conclusion, mining slurry pumps are a vital component of modern mining operations. Their ability to efficiently handle abrasive materials and transport slurries makes them indispensable in the quest for productivity and sustainability in the industry. As technology advances, the future of slurry pumps looks promising, paving the way for improved efficiency, reduced environmental impact, and enhanced operational reliability in mining.
