Preventive Roof/RIB Outreach Program (PROP)

  • A miner secures a roof brace
    Just Because It Is Supported Doesn't mean It's Safe

MSHA’s Preventative Roof/Rin Outreach Program (PROP) is an annual outreach and education program intended to increase awareness among coal mine operators and miners of the hazards that can lead to roof/rib fall accidents, and the precautions necessary to prevent these accidents.

Over the past thirty years, improvements in roof control technology such as new bolting systems, automated temporary roof support systems, use of cabs and canopies, and mobile roof supports have led to a significant reduction in roof/rib fall accidents and fatalities. Despite these gains, roof and rib falls continue to be a leading cause of accidents and injuries in underground coal mines.  In 2014, nearly 300 miners were injured from roof and rib falls.  Nearly all of these accidents occurred while the miners were under supported top.  With this in mind, MSHA’s 2015 Preventive Roof/Rib Outreach Program (PROP) focuses on roof and rib fall accidents occurring in supported areas.
