UNDERGROUND

Mining and blast design for underground operations is a core component of the Heilig & Partners consulting activities. Heilig & Partners have provided consulting services in the areas of blast design, including the assessment and optimisation for all aspects of underground mining.

Blast patterns for small diameter, narrow vein cut and fill operations through to large diameter, sublevel open stoping mines can be provided. Similar studies have been completed for operations in Australia as well as many overseas countries. Analysis of underground initiation sequences, the distribution of explosive, application of different explosive types and loading densities and the resulting performance impacts are key elements of the review process.
