conventional mining machine

In the conventional method of coal mining, several machines are used in a cycle of operation: undercutting or top cutting the seam with cutting machines next, they blast down the face then they load the coal with a mechanical loader and transportation of the coal from the face by

Machines are the way of the future and are safer than DB operation, but to realize these advantages mines need to invest not only in purchasing the machine, but also in training the crew and hiring skilled workers to run the machines, said Rostami With conventional mining you have a 20 m turn radius TBMs have a 300 m turn radius
