Risk Assessment

Scope: This risk assessment will encompass Group 3’s design prototype for a crusher loader, in the context of metalliferous underground mining operations. The prototype in question is similar to a LHD, with one major discrepancy: when filled, the front-mounted bucket lifts over the chassis and drops its load onto a sloped chute running on the long (i.e. front-back) axis of the vehicle.

Matrix scale: 

Hazards:

Ore escaping chute: The momentum of the ore load due to the bucket’s movement could cause it to deflect off the sides of the chute and into the surrounding passage. This has the potential for serious injury to any nearby workers, and could cause a blockage behind the vehicle.

Unmodified risk rating: 5D (V. High risk)

Current controls:

- Curved chute (top face open)

Controls to be added:

- Completely enclosed chute (top face closed)

- Safety procedures to ensure personnel maintain a safe distance when the vehicle is active

- Slower bucket movement to decrease momentum of ore

Modified Risk rating: 3A (Low risk)

Particulate matter: The bucket dumps its load onto the chute with a significant enough force to raise dust, and small particles of broken up ore, into the surrounding air. This brings the risk of inhalation of harmful particles to workers in the vicinity, as well ...
