Cablebolting in underground mines

Cables are one of the only options for support of inaccessible rock faces for stability and dilution control. Dilution control can have a very direct and large influence on the cost of a stope. The cost of dilution is many-fold: waste rock with little or no economic value is mucked, trammed, crushed, skipped, milled and impounded in a tailings disposal area, all at great cost.

Epiroc’s cable bolting rig is a fully mechanized rig for long-hole drilling and cable bolting in underground mining applications. Its unique two-boom concept makes it possible for a single operator to drill and install cable simultaneously.

Cable Bolting. Cable bolting is an established technique used extensively for reinforcement of the rock mass adjacent to surface and underground rock excavations. Cable bolts are long, fully grouted, un-tensioned reinforcing elements. The objective of cable bolting is to improve the shear and tensile strength of the rock mass.

Epiroc’s cable bolting rig is a fully mechanized rig for long-hole drilling and cable bolting in underground mining applications. Its unique two-boom concept makes it possible for a single operator to drill and install cable simultaneously.

In underground mines around the world rigid bolts and cable bolts are installed either by a manual or mechanized reinforcement practices. With the current mechanized cable bolting technology passive support is provided by installing fully grouted long cable bolts from a reel and mechanized active support is only provided by conventional

The objective of this thesis is to expand upon the existing database of cable support practice, and develop revised design criteria for the support of underground openings. A new empirical database of 46 supported case histories was assembled from a six month field study,involving visits to 13 mines in Western Canada, the United States, and Ireland. A comprehensive review of current cable ...

Anchors and Rock Bolts - Cable Bolts for Mining Cable Bolts for Mining are used for temporary and semi-permanent rock reinforcement in underground Mining. Rock bolting with prestressing steel cable bolts combines low bolt weight with high load-bearing capacity. The system remains flexible even with larger cable bolt lengths.

Plain cable bolts are prepared for installation by attaching a breather tube to the full length of the bolt. An excess of breather tube, approximately 2 metres, to protrude from the hole mouth. These cables can also be installed using an alternate "retreat" grouting method by withdrawing the grout tube from the hole.

Cable bolting is an established technique used extensively for reinforcement of the rock mass adjacent to surface and underground rock excavations. Cable bolts are long, fully grouted, untensioned reinforcing elements. The objective of cable bolting is to improve the …

Rockbolts and cables Introduction Rockbolts and dowels have been used for many years for the support of underground excavations and a wide variety of bolt and dowel types have been developed to meet different needs which arise in mining and civil engineering. Rockbolts generally consist of plain steel rods with a mechanical or chemical anchor

underground trials are presented. BACKGROUND In their comprehensive handbook on cable bolting Hutchinson and Diederichs (1996) introduce the cable bolting cycle (Figure 1), "a cyclical, iterative process which should be worked through a number of times as mining progresses to ensure that the cable bolting process is well tuned". It

Part 1 provides guidance on bolting plant for strata support in underground coal mines. Part 2 provides guidance on portable hand held bolters and is derived from MDG 5:1994 . Since the transition from timber roof supports to roof bolts, rib bolts, mesh and W-straps the use of bolting plant in underground coal mines has markedly increased.
