Tunnel Chain Saw Machines in China

Cavern-type chain saw is special for marble hole mining, crawler walking conveniently and flexibly, its orbit can rotate 270 degrees, which has 4 kinds of working model---horizontal cutting(cutting the top of ceiling and ground),vertical cutting(cutting left side of the facade and the right side of the facade),suitable for the quarries with high steep slope and can't excavate mountain skin layer and do overburden stripping.

Underground chain saw can extract high grade marble directly without striping mmaintain skins or soils.
Less requirement on lamd expropriation, less wastes and rubbles, less cost on deslag and revegetation, less environment damage.
Better block shape and higher yield rate
High extracting efficiency without being affected by wether. Even higher efficiency of future expending extracting to sides or downward
Low overall cost and low risks. High long term benefits
