Applications:
• Underground mining
• Quarry benching operations
• Water well drilling

Charateristics:
The drill bit is the main component of the drilling rig and is the tool that transmits the impact energy and makes direct contact with the rock to blast.

The drill bit is subject to complex forces throughout its operation, so there are high requirements for the material and shape of the manufactured bit. When operating with the eccentric drill bit, it is necessary to grasp the technical essentials. The drilling parameters selected should be based on the principles of low speed, low feed pressure and high upward wind speed, and the drilling speed should be controlled during the construction operation according to the hardness, looseness and water content of the rocks in the stratum drilled. When the drill encounters a particularly loose or large fissure stratum, it is especially necessary to reduce the feed speed and feed pressure and repeatedly discharge slag to clear the hole.


Advantages:
• High drilling efficiency, long drilling tool life, submersible impactor drilling, the medium is air, no flushing media recovery
and disposal problems, reducing the auxiliary time.

• Low cost of use, the submersible impactor requires small shaft pressure and low speed of the drilling rig, while the torque is low, so the natural power consumption is small, and the diameter of the drill pipe is relatively thin, easy to install and disassemble, and the service life is long.

• Submersible percussion drilling, the hole wall is more complete, there is no pollution from other media, basically can preserve The original formation structure and water permeability can be maintained, which reduces the well washing time and saves costs.

• In severe leakage formations and unstable hole wall formations, the submerged percussion can be used to follow the pipe drilling to completely solve the problem of repeated operations.

• As the submerged hole impactor uses wind as the power source, it greatly reduces the workload of cold-proofing in the previous winter construction due to the severe cold winter construction.
