Structural Hazards

Structural hazards include hazards related to the architecture of a mine site, such as roof support and the ground conditions. Safe ground conditions are important throughout the life of a mining process. The surface above abandoned mine openings, caves, and open pits can collapse without warning. Overhanging ledges can fall with the least amount of pressure. Unsafe ground conditions exist as a hazard not only to those walking on unsafe ground conditions but also to those who are below.

Mineworkers must often use difficult terrain to travel to and from work areas within a mine. Unstable ground should be isolated from mine workers until it is fixed. The stability of pit walls, benches, slopes, or any place where miners travel should be examined often and properly maintained. Any access exceeding an inclination of 50 degrees must be secured with stairs or a ladder.

The employer should implement a ground control plan at the mine site. The ground control plan contains a written plan of action that states and demonstrates how an area will be developed and maintained for the safety of anyone working in or traversing that area.
