Fragmentation, Cost and Environmental Effects of Plaster ...

Oct 20, 2014· The main advantage of the new stemming method is the reduction in the cost of blasting. At a basalt quarry, blasting costs per unit volume of rock were reduced to 15% by increasing burden and spacing distances. In addition, better fragmentation was obtained by using the plaster stemming method.

Sabinet | Mine haul road maintenance management systems

In surface mining operations, ultraheavy trucks operate on haul road networks which are typically from 10�40 km in length. These road networks are often not optimally designed and maintained and as a result, identifying and remediating road functional defects is problematic. Most surface mine operators agree good roads are desirable, but find it difficult to translate this into an ...
