Preventive Roof/RIB Outreach Program (PROP)

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.
