The Hybrid Mining Bolt Swivel Anchor is an anchorage connector for fall arrest, restraint, work positioning, rope access and rescue systems. Rotation of the bolt moves the end termination out or in to expand or contract two wedges within a 47mm friction rock bolt. When the wedges are fully contracted, the anchor can be removed from the friction rock bolt for reuse.
A mine roof bolt for use with resin including a strand cable. The bolt includes a head mechanism attached to the strand cable which preferably allows the strand cable to be turned in a first direction for mixing the resin and in a second direction opposite the first direction for tensioning the strand cable in the mine roof; although mixing and tightening can occur in the same direction.
Abstract: Cable bolting is rapidly increasing in popularity in underground mines as safety standards are raised and mining environments become more challenging. Traditional hand installation of cables can be time consuming, exposes personnel to unnecessary risks .
A simple power and data cable connects the HMI station to the EBox. The operator uses the HMI station to control and monitor all drilling and bolting functions. Operator Safety. The roof drilling syste m significantly improves the comfort and safety of mine workers in three ways: 1. Reduction of hand and arm strain injuries; 2.
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.
