Raise boring is used to drill shafts for ventilation, transferring ore from one level to another, creating silos for storing rock as well as hoisting of rock and ore to the surface. The application of Raise boring in mining also assists in providing access for personnel or material underground.
Jun 10, 2020#0183;#32;Mechanised raise drilling should however be considered a viable drilling application for raise boring in massive mine applications. Slot raises refer to relief holes within a stope, intended to provide void space (or burncuts) for blasting, thereby allow expansion of the blasted rock and to improve fragmentation.

A raise borer is a machine used in underground mining, to excavate a circular hole between two levels of a mine without the use of explosives.. The raise borer is set up on the upper level of the two levels to be connected, on an evenly laid platform (typically a concrete pad). A smalldiameter hole is drilled to the level required; the diameter of this hole is typically 230mm 445mm (9quot; 17
raiseboring machine, it is important to be aware of the rock characteristics, strengths and elasticity/toughness before considering the diameter and depth of the raise to be excavated. A raiseboring raise the bar Ailbhe Goodbody examines recent trends in raise boring and some of the mining projects where it is currently in use A
Mar 23, 2020#0183;#32;Traditional raise boring machines used to drill slot raises are cumbersome to transport and have high demands for labour and time. It can take two to three days of preparation before drilling
Epirocs range of raise boring machines includes models for both conventional raise and boxhole boring as well as down reaming and it covers diameters from 0,5 meters up to over 6 meters. The boring drills are used in both civil engineering and mining applications for drilling shafts for ventilation, drainage, ore passes, back fills, hoisting, slotholes, and penstocks for hydro power plants.
Model Selection of Raise Boring Machine in This Case: 1. Choose hole drilling and expansion 2. Choose raise boring machine parameter. Although this project only drills 100m, considering actual application and other practical conditions, /400 (LM400) raise boring machine is chosen. Technical parameters of /400(LM400) are as below:
offers the Robbins 123RVF C raise boring machine which is a very powerful raise drill. It can be used as sinking shafts in mining or civil engineering applications. It is an ideal choice for use in large diameter and long hole raise boring applications. RCS control system is provided for controlling torque and speed.
