Description

Technical Field

[0001] The utility model relates to the technical field of roadheader-anchoring machines, in particular to an independent working multi-arm roadheader-anchoring machine. Background Technique

[0002] Due to different geological conditions in underground coal mines, there are various tunneling processes, such as "one tunneling and one anchoring", "one tunneling and two anchorings", "one tunneling and three anchorings", and "long tunneling and long anchoring with large step distance".

[0003] Due to the requirements of safety management, production management and cost management in underground coal mines, the transportation system also adopts intermittent transportation during production shifts. To improve the tunneling efficiency, the "one tunneling and two anchorings" method is adopted for coal mine roadway tunneling.

In order to take into account the intermittent transportation of the transportation system and the timely support of the roadway roof, there is an urgent need for a multi-arm roadheader-anchoring machine in coal mines with a flexible support system, convenient operation and high tunneling and support efficiency.
