Explosive work is another crew” refers to a common organizational practice in underground mining operations, where blasting (or “explosive work”) is handled by a dedicated team separate from the main production or development crews for safety reasons.[sec]
Safety Rationale
This separation ensures that no personnel remain underground during blasting cycles, minimizing risks from fumes, flyrock, or misfires. After blasting, the area is ventilated and inspected before other crews re-enter, following standard protocols like those in NI 43-101 mining reports.[sec +1]
Mining Context
In projects like the Duparquet Gold Project, dedicated roles such as “Mine D&B Supervisor” (drill and blast) operate on shift rosters, distinct from haul truck operators or maintenance teams. This structure supports efficient scheduling, with explosive magazines and specialized equipment for ANFO or emulsion blasting.[sec]
Operational Benefits
Assigning explosives to another crew reduces downtime and enhances productivity, as seen in manpower tables where drill/blast positions scale independently (e.g., 2 supervisors per shift). It aligns with geotechnical and regulatory standards in hard rock mines.[sec +1]
