Correct cleaning method of drill pipe for underground mining

When cleaning the underground mining drill pipe of the rotary excavator, we must first understand the cause of the sediment at the bottom of the hole. The main reasons are that there is residue between the bucket teeth of the rotary drilling rig and the bottom cover of the drill bucket; the bottom cover is not closed tightly; Sometimes even all of it is lost in the borehole; the soil cut by the outer edge of the bucket of the rotary drilling rig remains on the edge of the bottom of the hole because the bottom of the hole is flat and cannot enter the entrance of the cylinder; the bucket teeth of the bucket are sparsely arranged, Interdental leakage is unavoidable; the drilling footage is too large, the loading is too full, and the muck is squeezed out from the top cover drainage hole. _Drill pipe for underground mining_Drill pipe for surface mining_Drill pipe manufacturer
According to the characteristics of the rotary drilling rig construction method, we can control the speed of the sedimentation speed of the soil residue by changing the specific gravity difference between the soil residue and the mud and increasing or decreasing the viscosity of the mud. Increase the specific gravity and viscosity, on the contrary, we can reduce the specific gravity and viscosity to speed up the settling speed of the rotary drilling rig underground mining drill pipe soil slag. _Drill pipe for underground mining_Drill pipe for surface mining_Drill pipe manufacturer
The underground mining drill pipe must be cleaned, otherwise the settlement of the pile top will be large and the bearing value will be reduced. The common methods of cleaning the underground mining drill pipe of the rotary drilling rig are as follows:
1. The cleaning of hydraulic parts should be carried out on a special cleaning table. It cannot be cleaned anywhere, away from pollution sources, and the cleaning site should be clean.
2. Kerosene, gasoline and hydraulic oil of the same grade as the working oil of the hydraulic system are allowed to be used for the cleaning fluid of the drill pipe for underground mining.
3. The cleaned underground mining drill pipe is not allowed to be wiped with cotton, linen, silk and chemical fiber fabrics to prevent the falling fibers from contaminating the system.
4. After cleaning, the components of the underground mining drill pipe are not allowed to be placed directly on the ground, cement floor, floor, fitter table and assembly workbench. They should be placed in a container with a lid and injected with clean hydraulic oil.
5. It is recommended to take protective measures for the cleaned underground mining drill pipe to keep it away from oxidation pollution.
