On December 2, 2016, a technical representative for a shield manufacturer, with 13 years of experience, received fatal injuries while adding components to the hydraulic system of a longwall shield. The victim was positioned inside the shield near the hinge point when the shield collapsed and crushed him.
- Ensure that miners who install, remove, or maintain shields are trained on proper procedures.
- Never remove hydraulic components without first determining if they are pressurized and/or supporting weight. Ensure all stored energy is released or controlled before initiating repairs.
- Never work on hydraulic components of both supporting cylinders of longwall shields simultaneously. A shield can collapse if hydraulic components from both cylinders are removed, even if both cylinders have functioning pilot valves.
- Never work on a component that supports a raised portion of the shield unless the shield is blocked against motion.
- Be aware of potential pinch points when working on or near hydraulic components. Examine work areas for hazards that may be created as a result of the work being performed.
- Maintain good communication with co-workers. Make sure those around you know your intentions.

On December 21, 2016, a 39-year old contract truck driver, with 11 months of mining experience, was injured on the surface of an underground gold mine. The victim was hauling gold ore in an over-the-road truck from the mine to the plant. While descending the roadway from the mine, the victim lost control of his truck. He traveled up an embankment and over an approximate 20 foot drop, landing back in the roadway. The victim was transported to the hospital and died from his injuries several days later.
