摘要

The U.S. Bureau of Mines conducted a worldwide literature review of bleederlessventilation practices to evaluate their use as a spontaneous combustion control measure in U.S. coal mines. Factors that must be taken into account in the design and use of these systems include seal construction, the use of ventilation control devices, the use of methane-drainage systems in gassy mines, and the ground control plan. Monitoring for the detection of spontaneous combustion and the control of methane when methane-drainage techniques are employed is critical to the successful use of a bleederless ventilation system. The report describes the types of ventilation systems used throughout the world and the spontaneous combustion risks associated with these systems.
