After the quarrying steps of 4~6m high are formed in the cave and the quarrying chamber of a certain space size, diamond wire saw can be used to carry out large-scale mechanized quarrying according to the process method of open-pit marble mining.
The quarrying method of caving marble mine is very similar to that of sunken open-pit marble. In addition to step quarrying, trenches and rectangular channels should be opened. The sunken open-pit marble quarry must constantly expand to the deep of the ore body and the horizontal direction of the trench in order to form an open stope.
While in cave-quarrying marble mine, the rectangular channel is continuously developed and expanded in the depth and horizontal direction at the top of the quarrying step. After reserving certain safety support pillars, new development channel, development chamber, quarrying step and quarrying chamber are formed, so that the cave-quarrying operation can continue.
There is a manufacturer in China, ToolWits, producing diamond wire saw machine for stone quarry, their team has a 14-year experience of stone industry and has a very advanced technology of stone quarrying. ToolWits will become the market leading target in China near the future.
