In our daily life, you could see the natural stone
withs,s or other types, which are widely used in the home interior or
exterior decoration, but do you know that it is a difficult task to cut
them into cubic blocks, then into the finisheds.
Would you like to know more about it? OK, here we go!The second method
is blasting. First drill hole on the ore body, put explosives inside,
and then blast the rock into large blocks
by blasting, finally drill the blocks into cubic blocks. Since the
shock wave produced by blasting has a bad effect on the ore body, the
general ratio of blocks yield is around 30%. Due to the cracks in the
blocks, while cutting it into sheets, the ratio of yield is below 50%.
Thus, both home and abroad prohibit the blasting method of quarrying for
the sake of resources.The third method is mechanical. Use a machine to
drive wire saw or
diamond wire saw to abrade circularly the ore body, and cut the rock
into blocks. This quarrying method can produce high ratio of block yield
and of yield, but it requires a great amount of investment in
mechanical equipment and technical personals to operate, thus this
method is suitable for quarrying in large-scale mines.
