Mining and Geology

Drilling and Blasting

Adequate rock fragmentation is one of the most important parameters affecting the productivity and ore extraction costs in a mine. Blast hole drill patterns have to be optimized and suited to the geological and structural properties of the rock. In order to avoid excessive levels of vibration and noise, the drilling and blasting procedures have to be adapted to the characteristics of the ore body.

Through the extensive experience that Met-Chem has acquired in projects all over the world, technical assistance provides a very efficient tool for reducing operating costs.
