An automatic braking system for mine track equipment was developed in compliance with Section 314(e) of P.L. 91-173 to prevent break-in-two and runaway accidents. The braking system can be defined as spring applied and pneumatically released. Service braking and an automatic electronic tachometer-type overspeed control were incorporated in the design. A 4-ton battery locomotive and five mine cars at the Bureau Safety Research Coal Mine were equipped with this automatic braking system. The report covers the state-of-the-art, maintenance, regulatory standards, and design standards for automatic brake applications.
