Far too many miners have been injured or killed in accidents involving powered haulage. The category, which covers the haulage of materials and personnel, accounted for half of the 28 US mining fatalities in 2017. MSHA has made the prevention of powered haulage accidents a priority for 2018 and beyond, with an initial focus on three areas: large vehicles striking smaller ones; seat belt usage; and conveyor belt safety. Materials on this and related web pages support the powered haulage safety initiative.
Large Vehicles Hitting Small Vehicles
Surface mining vehicles can be several stories tall and are capable of destroying smaller vehicles that cannot be seen by the operator. Traffic controls, training, and avoiding distractions are key to enhancing safety. Collision warning and avoidance systems can also help.
Seat Belt Usage
MSHA engineers estimate that three to four miners' lives could be saved each year if adequate seat belts were provided and worn. Warning systems such as chimes can remind drivers to buckle up, while interlock systems can prevent the vehicle from moving if the belt is unbuckled.
Belt conveyors and their components pose serious risks to miners working on or around them. It's important to install adequate guarding to prevent contact, provide and use crossovers and cross unders, and lock out energy sources and block motion whenever performing maintenance.
