Hydraulic Rock Bolting Rig for Mining Borehole
Bolting Jumbo is with only 2 parts, a tube and matching domed bearing plate. The high strength steel tube is slotted along its length. One end is tapered for easy insertion into a drill hole and the other has a welded ring flange to hold the bearing plate. With the bearing plate in place, the tube is driven into a slightly smaller hole, using the same standard percussion drill that made the hole. As the tube of the rock bolt slides into place, the full length of the slot narrows, causing radial pressure to be exerted against the rock over its full contact length.
In the hole, the tube exerts radial pressure against the rock over its full contact length, and also provides immediate plate load support.
I. Technology Introduction
Bolt jumbo support is a fast, safe and economical way to support coal mine roadways. This support method is widely used in major coal producing countries at home and abroad. The bolt support rate in foreign advanced coal mining countries often exceeds 80%.
In modern high-yield and high-efficiency mines, Continuous Miners and subsequent supporting equipment have become important roadway excavation equipment. Continuous miners are mostly used in room or room and pillar mining, and double or multi-lane rapid excavation, with high output and fast lane formation speed. Since the goaf roadway needs timely support, the bolt drill carriage is particularly important among the supporting equipment of the Continuous Miner.
II. Performance Characteristics
ADVANTAGES OF BOLT JUMBO EQUIPMENT
· Our products and equipment were originally designed for the mine: they are robust, without unnecessary sophistications, easy to use and maintenance.
· In order to reconcile competitiveness and performance, these devices are based on a constructive system of customized as standard!
· A team of engineers, technicians, hydraulic engineers and fitters provide design, development, assembly and start-up equipment on site in the world.
