1. Oil, gas, and mineral resources exploration 2. Engineering geological prospecting 3. Hydrological well exploration 4. Borehole in surface blasting 5. Gallery ventilation The crawler core full hydraulic drilling machine is a new type of integrated drilling rig developed on the basis of YG research and development of. .
(1) Full hydraulic drive, easy to operate; (2) Modular design, each component module is easy to assemble and disassemble. Also, it is convenient to derive series products, reduce the. .
Why do more and more people prefer to use crawler fully hydraulic core drilling rigs? There is no doubt that this is a good choice for operators.
[pdf] 1. Prepare the rock-drilling cavern, the specifications of which can be determined according to the method of drilling. Generally speaking, the height of the cavity is 2.6-2.8 meters when drilling a horizontal hole with a down-the-hole drill. When drilling upward, downward, or inclined holes, the width of the cavity is. .
1. When starting to work, carefully check whether the gas and water pipelines are firmly connected. Check for air leaks and water leaks. 2. Check whether the lubricator has been. .
When opening the hole, start the motor first, and pull the push handle of the manipulator after the transfer is normal. Make it get proper.

The mud circulation system plays a vital role in surface core drilling. It's like the life - blood of the drilling rig. The main purposes of this system are to cool and lubricate the drill bit, carry the cuttings out of the borehole, and maintain the stability of the borehole walls..
The mud circulation system plays a vital role in surface core drilling. It's like the life - blood of the drilling rig. The main purposes of this system are to cool and lubricate the drill bit, carry the cuttings out of the borehole, and maintain the stability of the borehole walls..
The circulation system on the rig is the system that allows for circulation of the Drilling Fluid or Mud down through the hollow drill string and up through the annular space between the drill string and wellbore..
The drilling mud circulation system ensures that the drilling fluid performs multiple functions, including mud cooling, bringing cuttings to the surface, and providing hydrostatic pressure to prevent blowouts. An optimized circulation system improves drilling efficiency.
