This compact explosion‑proof tunnel repair machine carries out roadway floor‑digging work inside a narrow coal mine.
After long‑term operation, roadway floor piles up gangue and sludge, which reduces passage height and blocks transportation. The machine removes raised rock and waste materials to restore normal roadway clearance.
With a narrow body design, it fits confined underground tunnels. The tracked chassis works well on wet and muddy ground. Its multi‑functional arm can finish digging, breaking and mucking tasks. It greatly reduces manual workload and improves roadway maintenance efficiency.
The picture shows real underground working condition with stable machine performance for long‑time mine service.
