Thermal Fragmentation as a Possible, Viable, Alternative
A current innovation in the mining industry, and in particular underground narrow vein mining, is the fragmentation of rock by use of extreme heat. While the use of thermal fragmentation in its current state is a new development, thermal spalling of rock has been in practice for over a century.

Rock Fragmentation by Blasting
The fragmentation of rock is fundamental to mining. It is the first preparatory stage in the extraction process – making rock small enough and loose enough to be efficiently excavated. But this simple statement underestimates how important this activity is for the whole mining operation. By optimising rock fragmentation by blasting, you can
