Hole Mining Chain Saw

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.

Advantages of using cavern-type chain saw
 
1. Don't need to do the large-scale stripping skin and mountain earth, it can mine the finest marble resources directly.
 
2. Less land acquisition and trees cutting , less slag and gravel, low cost of slagging and vegetation restoration.
 
3. Fast exploitation, good appearance of blocks, high blocks yield.
 
4. High production efficiency, it is not affected by the weather, day and night time, and it can control the mining speed progress, and has higher mining efficiency and benefit in the late stage when expanding to the left , right and downward sides.
 
5. Low comprehensive cost, good long-term benefits, low risks.
 
Analysis of mining efficiency (eg: DC-CS3000)
 
1.Each unit cutting size: Width(≥6m) × Height(5.5m) × Depth(3m)
2.Mining efficiency: Average 4 days/unit, synthesize 20 cubic meters/day.
               6000 cubic meters/year (24hours/day/300days)
