- Abstract
- An investigation into the requirement and fire test performance of conveyor belts intended for use in underground coal mines was conducted. The aim of this study was to develop recommendations for the Mine Safety and Health Administration (MSHA) on a test method suitable for measuring the fire hard potential of a conveyor belt in a coal mine environment. A review of incident data, large-scale test, and small-scale test was conducted to provide the neccessary information. The incident data was analyzed with the goal of developing scenarios that could form the basis for a suitable test or to evaluate the appropriateness of the existing test. Large-scale tests were reviewed to determine anticipated belt fire performance under "realistic" end-use conditions. The test showed how geometry, input energy, and ventilation controlled belt fire performance. Small-scale tests were used to provide information on specific fire properties such as ease of ignition, flame spread, and smoke generating potential.
