Bolter Miner Roadheader with 4 bolters for roof supporting and tunneling
Bolter Miner Roadheader with 4 bolters for roof supporting and tunneling
The alpine bolter miner is a comprehensive equipment integrating cutting, loading, walking and bolting operations. It is used for roadway tunneling operations and has the function of bolting, thus realize the rapid tunneling in the coal roadway, semi-coal rock roadway and soft rock. integrating the
the tunneling and bolting functions. the two functions do not intefere with each other, and the mechanized drilling of the anchors or cables hole at different heights and angles in the roadway can be realized, which greatly reduce the supporting time and improves the tunneling efficiency. remote control and manual control equipped with temporary support function. increases the safety of the workers.
