Boxhole Drilling Depth 60m Raise Boring Machine For Blind Hole Drilling

Introduction:

CY-R40C blindhole raise boring machine is the first one in China, which is especially used in the excavation of various opening holes. And when it adopts the boxhole drilling methods, its diameter can reach 670mm, and the depth can reach 60m. CY-R40C blindhole raise drill has the advantages of fast rotary installation, safe and efficient operation. In addition, the blindhole RBM can propel itself without the concrete platform. The technical indexes of the blindhole raise boring drilling rig are in the leading international level, which can fully meet the construction requirements of blindholes in various types of underground mines.

Application:

The Box Hole Raise Boring Rig is used when there is not enough space on the higher of the two levels to be connected. it can safely, accurately and economically drill medium and large holes, such as: precondition holes, paste fill tube holes, media holes, slot holes, back filling holes, ventilation tunnels, slot raises, through passes, drainage holes, ventilation holes, filling holes and cable holes.

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
