Cable Bolt Bulbed Dsi Underground Australia

In coal mining applications, the preferred hole diameters are 3536mm for single bulbed cable bolts and 50mm for double bulbed cable bolts. Holes are drilled approximately 200mm shorter than the bolt length. If the bolts are to be tensioned, a tail of between 200 to 500mm is required dependent on the type of tensioning unit to be used.

Cable Bolting

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.

Roof Bolting In Underground Mining A Stateoftheart

With continuing investigations and developments, roof bolting today can in most cases successfully reinforce the mine roof in underground mining. In order to cope with the increasing use of roof bolts, efforts should be made to maximize the safety and minimize the cost. With regard to mechanical bolting, two important parameters need more advanced improvements and study, namely, optimum design ...

Quotstudy Of Cable Bolt Shear Strength Characteristics For

Bolting is currently the most commonly accepted rock reinforcing method of dealing with rock strata instability in both surface and underground mines as well as civil engineering. Bolts are installed in fractured rock mass to build composite beams in weak strata or to attach weak excavation surfaces to deeper and competent rock layers to achieve stability. After opening, rock mass around the ...
