Product models include: EJM400/4-2, EJM400/4-4
The EJM400 series bolter miner integrated machine integrates cutting, loading, transportation, bolt support and spray dust removal. It is an efficient tunneling equipment for coal and semi-coal rock roadways, divided into synchronous type and asynchronous type. The synchronous type bolter miner integrated machine performs cutting and bolt support simultaneously, suitable for rapid tunneling of roadways with stable roofs. The asynchronous type bolter miner integrated machine has the roof bolt drills arranged forward, with unsupported roof distance ≤1000mm, suitable for rapid tunneling of roadways with complex conditions and relatively broken roofs and sides
