What is smooth blasting?

Smooth blasting is to drill a row of (circle) dense blastholes on the contour or excavation edge so that the resistance line is larger than the hole spacing. When blasting, a rupture zone is formed along the blasthole line to obtain a flat rupture surface. Generally, smooth blasting is initiated once after the main blast hole is blasted or after cleaning. After smooth blasting, the forming is regular, not over-excavating, meeting the design requirements, the new slope is not damaged, and the stability of the step is guaranteed.
The smooth blasting mostly uses uncoupled charge. The open blast and underground mines use this blasting method in the field work. The schematic diagram of the typical scheme is shown in Figure 1 and Figure 2.

The charge of each blasthole in rows 1, 2, and 3 is 108kg, 90kg, and 72kg, respectively.
It is necessary to explain that the smooth blasting construction process must be strictly in accordance with the design requirements to ensure the blasting effect.

Stainless Steel Plain Weave Mesh

Stainless Steel Plain Weave Mesh

Stainless steel woven wire mesh can be used in filtering liquid gas and pulp. The opening can be square ,rectangular or special opening. Normally, this kind of wire mesh has standard opening sizes, uniform opening ,good permeability and high strength. The raw materials should be chosen according to different environment of applications.
