Compact High pressure Portable Water-jet Coal Mine Cutting Case Introduction:

Case location: Shenmu Shenhua Shendong Coal Mine

Compact high pressure water-jet Portable cutting process is the Cold clean cut without the risk of explosion or cause inflamed, and also the high-pressure water-jet cutting (also known has hydro cutting) supercity which it doesn’t generate heat, stress or distortion in materials, the High pressure Portable abrasive water-jet Concrete Steel plate cutting machine widely applied in waste tank hole cutting, gas pipeline cutting, line of intersection and profile cutting, and the sheet plate cutting etc.

Our Case is Coal Mine Cutting,Due to the high pressure and broken roof during coal mine tunnel excavation, anchor rods are usually used to support the roof in the tunnel and anchor cables are used to reinforce the roof. In coal mine excavation production, anchor cables are used frequently, and the removal of anchor cables is also very difficult. In view of the current situation of high risk of cutting anchor cables underground in coal mines, large demand for cutting work and low efficiency, our company and Shenhua

The group cooperated to develop small low-pressure water cutting equipment suitable for underground coal mines.

The location of this cutting demonstration is in a coal mine factory of Shenhua Group, and it is required to anchor the tunnel

The exposed part of the cable is cut off to complete the removal of the roof pallet. Anchor cable to be cut

The diameter of the tool is 7-9cm, and the diameter of the steel strand is 2-4cm. This demonstration uses our company’s Special tooling developed for anchor cable cutting, which adopts a swing cutting method from the root of the anchor cable method, cut off the steel strand of the anchor cable, then remove the anchor and steel strand, and finally remove the anchor

Dismantle the disc and complete the entire cutting task,

After a large number of tests, it has been proved that the use of portable water cutting technology can more safely and effectively realize anchor cable cutting operations in coal mines, reduce workers’ labor intensity, and reduce work risks.
