raise boring and the effects that these may have on future underground mining. The idea of raise boring application in mine production may not be brand new, but recent results may initiate a revolution in thinking, and possibly create a new mining standard. Raise boring …There are three types of raise boring methods utilised in the mining production and development industry: Standard Raise boring, Down-Reaming, and Box-Holing. These all commence with the process of drilling a pilot hole (small diameter drill hole) from base level to the required level. Once the pilot hole is achieved to plan, a large diameter ...

Figure 3 Raise Boring Machine Negatively Hole Reaming Process. In this example, ZFY2.5/400 (LM-400) anti-drilling rig is used to drill, first drill 270mm guide hole until the guide hole drills through the lower roadway, then remove the guide hole drill bit, and connect the 2m diameter reaming drill bit.Peruvian mining contractor INCIMMET deployed a custom-built TR2000+ raise boring machine to excavate the shaft in challenging ground conditions, which consist largely of andesite-porphyry, diorites and monzodiorites with intrusive hydrothermal gaps within the volcanic and sedimentary sequences.

article discusses the recent developments in raise boring and the effects that these may have on future underground mining. The raise boring application in mine production may not be brand new, but recent results may initiate a revolution in thinking, and possibly create a new mining standard. Raise boring requires brute strength to break the rock.Though this method can be used in all facets of mining, it is increasingly replacing the use of hand-held mining techniques that have the inherit hazard of placing a miner in a raise. Redpath's compact Redbore raise drills have the ability to handle boxhole drilling without sacing space within the mine.
