- Summary
- "The purpose of this study is to review the various causes of coal dust explosions and to summarize the preventive measures through which it may be possible to minimize the hazards of coal dust explosions. The properties of coal dust which have an important influence on its explosibility are: fineness, purity, percentage of volatile matter, dryness, age and degree of oxidation, lifting velocities and dispersability, and its static electrification. Explosibility of coal dust has been studied in laboratories, in explosion galleries and in an experimental coal mine. The data and results obtained from the tests showed that finely pulverized coal dust has a lower explosive limit of 0.035 to 0.08 ounces per cubic foot. Although formation of coal dust is not possible to prevent, its dispersion can, however, be considerably reduced if proper preventive measures are adopted. Application of water during the various phases of mining is an effective means in many instances for reducing the quantity of fine coal dust dispersed during mining operations. One of the most practical measures is a generous application of rock dust in the mine workings. The requirement of 65 percent of incombustible material in coal mine dust provides a comfortable factor of safety against coal dust explosions. Other major preventive measures which can be adopted include rock dust barriers, concrete stoppings, and pressure relief vents in their various forms and modifications"--Abstract, page 1
