Blast Management

Blast Management International
Drill and blast consulting

Specific Services include:

Audit of drill and blast operations
Existing operations may be audited to determine the effectiveness of design implementation and the effects of process variation. An initial system audit may focus on the process and procedural documentation followed by a compliance audit to establish the effectiveness of the system in managing the drill and blast operation. Audit results document achievable and effective recommendations to address identified issues.

Risk management
Area of specific risk may be analysed in order to understand operational exposure and the necessary changes and controls to manage such risk. Examples include estimating blast clearance areas, business and safety risks associated with specific operations.

Drill and blast systems development
The implementation of procedures, operating instructions and quality standards is a key to effective blast management. Blast Management International provides a facilitation service to enable sites to grow their own system from the ground up. Whilst model procedures are supplied for this process site involvement is necessary for ownership.

Blast design
Blast Management International is able to provide specific blast design for underground and surface blasting operations. Designs combine fundamental explosives / rock properties with blast performance history from a range of sites. This approach is particularly effective when blasting in new or unusual blast geometries.
