Boxhole Raiseboring Rig for Max. Diameter 670mm Filling and Cable Holes Similar with Easer L

Introduction and application
Our boxhole raise drill is used when there is not enough space on the higher of the two levels to be connected. It is mostly used to create filling and cable holes, ventilation tunnels, slot raises, precondition holes, paste fill tube holes, media holes and through passes and tunnels used to extract ore.

It can drill boxhole up to 60 m depth and 667 mm diameter and has the capability to drill angled holes in different direction.
Our boxhole raise drilling rig is a low profile raise boring machine drilling rig, suitable for holes from 220 mm to 1400 mm in diameter. This powerful boxhole raise boring machine can handle most rock types and provide you with the power needed for a small space. Our raise boring drilling rigs moved quickly in place, eliminating much of the time-consuming preparation required by traditional boring machines. When access to the lower levels of the mine is limited, it will add power and flexibility to your operation.

Advantages

Drilling methods

1, Boxhole Drilling
In the underground mine caving mining process, the boxhole drilling is generally used to provide buffer space for blasting. The boxhole RBM replaces the manual boxhole drilling to be safer and more efficient. It can drill holes with diameter 670mm and depth 60m.
2, Longhole Drilling
The boxhole raise boring machine can use the tricone bits to quickly and accurately drill various large diameter deep holes with max. diameter 220mm and max. depth 200m.
3, Down Reaming
It is difficult to pass in underground mine, the down reaming is adopted. It can drill holes with a diameter 670mm and a depth with 200m. The pilot hole can be used for guiding and slagging discharge. 
4, Down Raising
In the VCR mining process, the boxhole raise is required to provide buffer space for lateral blasting. It is an ideal choice for boxhole raise boring with a flexible, safe and efficient boxhole RBM. In this drilling method, the depth can reach 200m, and the diameter can reach 1400mm.
