Application of Splitting Blasting in Quarries

摘要

In shaped stone blasting industry, the gunpowder explosive blasting and non-coupling charging blasting are generally widely used. As fine and small crack and split exist in rock, when the above-mentioned blasting methods are used in mining, the rock are not split in given direction. What we should do is tryings to use new materials, emphasized on changing the inner structure of the product, adjusting the pressure state in all directions in blast holes, for purpose of obtaining desired blasting results. At first, the splitting should not effected by cracks and rock split property in different direction, and the rock will be split in given direction. And intact wall of blast holes is guaranteed after blasting. The smooth blasted and separated face is obtained and the blast hole distance is increased. Any face can be cut, with blasting method according to actual need, forming cut and cut gap, then large size piece can be moved and separated from the rock.
