Drilling Rate Index (DRI): DRI is a relative measure of penetrationrate and used as a standard test procedure in the industry. Rating 10 – 100, the lower the number, the harder to drill. TheDRI is determined on the basis of two parameters: Rockresistance to crushing – Brittleness value S20. Rocksurface hardness – Siewers J value (SJ value)

A key application of blast mats in mining is for obstructing rock falls and bursts. When bolted against the wall, the mesh can stand as a barricade. As passive support, blast mats are available to block plummeting masses. You can fix the blasting mats to the walls without extensively stressing the rock because they''re lightweight yet sturdy.
