The main components of submarine hammer drilling equipment include the drill rig, hammer, drill pipes, and the drill bit. The drill rig is often mounted on a surface vessel or a floating platform and is designed to support the excessive weight and dynamic forces encountered during drilling operations.
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. The roller drill uses the rolling action of the roller bit to break the rock and is suitable for drilling holes of 150 ~ 440 mm in diameter on the hard rock. It has the advantages of high efficiency and low labor intensity, and is widely used in large and medium-sized open-pit metal mines. The drill consists of an impactor (or drill bit), a rotary mechanism, a lifting mechanism, a pressure device, a walking mechanism, a slag discharge system, a drill frame and a drill pipe. Rotary drilling machines are only suitable for drilling softer minerals and coal. The common feature of these devices is that the degree of automation is getting higher and higher, and some functions realize the application of intelligent i GPS technology on these RIGS, which realizes the automatic positioning of the boom, saves the time of field marking and positioning, improves the efficiency of the operation, and enables the operator to concentrate on monitoring the process of drilling. At the same time, more attention is paid to safety and environmental protection and the improvement of human-machine relationship. With the impact of the implementation of engine emission regulations, mobility, intelligent handling and environmental regulations Tier 3/ Euro ⅢA emission regulations, most foreign rig manufacturing companies have adopted diesel engines that meet the emission standards
2. Versatility Fractional head hammers can often be adapted for various tasks, eliminating the need for multiple hammers. For instance, one section may be designed specifically for driving nails, while another could be used for shaping or forming materials. This versatility saves time, reduces the number of tools needed on-site, and allows for greater efficiency in workflow.

Portability and Convenience
Given Mars' low-pressure environment, the search for life has become increasingly complex. While the thin atmosphere presents challenges, it also raises intriguing possibilities. Life that could potentially exist on Mars might have adapted to these harsh conditions, thriving in subsurface environments where pressure is higher and water may remain stable in liquid form.
3. The speed of the pump is too high, in the metallurgical industry or heavy medium coal preparation containing large particles, the speed is too high, which will greatly shorten the service life of the pump flow parts, cause the user to increase the cost, on-site maintenance frequency and other problems.
