مصنع لتجهيز البوكسيت/Prospector Directional Drilling Rock Hammer
· Downthehole percussive hammers are very costeffective for drilling hard rock. They are used for waterwell drilling, blasthole drilling, surface mining, and exploration for gas and were introduced to the directional rock drilling industry about three years ago.
drilling fluids reduces the drill pad size, may require fewer disturbance permits, and eliminates the need to back fill a pit. AIR HAMMER DRILLING Air hammer drilling forces compressed air through the drill pipe to drive an air hammer bit at the bottom of the borehole. The pneumatic bit rapidly strikes the rock.
The drill has been extensively tested in the Arctic, Antarctica, and Mars chamber. The system demonstrated drilling in rocks, ice cemented ground, and ice with low power (100200 Watt), low Weight on Bit (<100 N) and high penetration rate (1 m/hr). The next generation drill called the LITA drill .

Pilot Hole Directional Drilling Pilot hole directional control is achieved by using a nonrotating drill string with an asymmetrical leading edge. The asymmetry of the leading edge creates a steering bias while the nonrotating aspect of the drill string allows the steering bias to be held in a specific position while drilling. If a change in ...
· Produced by rock drill or hammer's impact energy and frequency. Typically between 1500 to 3600 hits per minute. Compared to pneumatic drills, hydraulic drills are capable of higher percussion power and faster penetration rates. Percussive drill rig is built around the hammer or rock drill. in percussive drilling rock is broken with impact energy.

Today we provide 4 Rock Solutions. ROCK SAW TRENCHING. ROCK DRILLING by Horizontal Directional drill and air hammer. ROCK excavation by surface mining. ROCK BREAKER.
A rotating drilling head is used to pierce and reduce the rock (or sail) into cuttings. Before beginning this type of drilling, an entry pit and an exit pit must be dug to the required depth. It should be noted that it is possible to drill at a required slope, but it is impossible to perform a curved trajectory (as it can be done with directional drilling).
directional drill into a highly productive rock drilling machine, the Roughneck Rock Hammer is capable of drilling at rates up to 150feet per hour with exceptional steering performance.
