Tunneling Roadheader Machine Underground Working

Tunneling Roadheader Machine Underground Working The Roadheader is a continuous mining and tunneling machine that can economically excavate a wide range of rocks. The Road Header can be used for building mine entrances, galleries, tunnels and for mining coal and ore.The tunneling roadheader does require a greater investment than an excavator with a roadheader attachment. The excavator’s performance, however, is limited because it is dependent on the hydraulic power capabilities of the excavator. Attachments are extremely flexible in large tunnels for scaling, cutting manholes, corners and excessive grouting.  A disadvantage of using an excavator with roadheading attachments is its inability to remove muck simultaneous to cutting; it must be stopped and moved in order to clear muck, which results in a reduced production rate, which includes cutting the material as well as moving it behind the machine.Suitable for the tunnengling of coal tunnels and mixed coal-rock tunnels con…
