Double Boom Type Underground Mining Roof Bolter

Underground Mining Roof Bolter

All bolting jumbo rock reinforcement drill rigs convey safety. They fit to all ground conditions and offers flexibility in length and type of bolts as well as rapid bolt type conversion.
In addition to the comprehensive set of advanced features, the our rock reinforcement rigs also have automatic resin cartridge injection as a new option. Due to the usage and safe location of operators are no longer exposed to fumes. It provides cartridge sequence that can be either programmed and endlessly replicabled or set manually for each bolt. This feature ensures that the operator can easily adapt the grouting to what requires the ground conditions.

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.
