Moreover, the advancements in drilling technologies and techniques have made it possible to achieve highly efficient perforation results. Digital technology, computer modeling, and simulation are utilized to anticipate how the geological formations will respond to drilling activities. By utilizing advanced analytics based on parameters such as 3 32, engineers can devise optimized perforation strategies that align with both production goals and regulatory standards for environmental protection.

At its core, submarine hammer drilling employs a powerful hammer mechanism to drive a drill bit into the seabed. The system utilizes both air and water pressure to deliver repeated impacts on the drill bit, which enables it to break through hard rock formations or sediments that might hinder installation efforts for marine infrastructure. The design of the hammer ensures that the energy is efficiently transmitted to the drill bit, allowing it to operate at significant depths.

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.
