CDC Mining Feature Coal Mine Explosion

Prevention of coal mine explosions requires a suite of control strategies, including sustaining a properly designed ventilation system, adequate sealing of abandoned areas, aggressive and frequent monitoring of methane, reduction of coal dust accumulations, and control of potential ignition sources through electrical safety and the use of permissible equipmentcoal dust explosions and to sunnnarize the preventive measures through which it may be possible to minimize the hazards of coal dust explo sions The properties of coal dust which have an important influence on its explosibility are: fineness, purity, percentage of volatileCoal dust explosions and their preventioncoal and the high temperature inside the mill lead to rapid oxidation of the coal This results in further heat buildup and the potential for a fire If the mill is restarted without first removing the hot coal, an explosion can occur when particles are COAL HANDLING SAFETY AMETEK LandMajor coal mine explosions in the United States, 1970–present 78 6–2 Gassiness of coal seams Subsequent chapters describe methane control methods for different kinds of mines and mining equipment, primarily for US coal minesHandbook for Methane Control in MiningBasics of Explosion Protection INTRODUCTION HAZARDOUS LOCATIONS INNOVATIVE EXPLOSION PROTECTION by R STAHL 18007824357 Class I, Locations Class I locations are those in which flammable "gases or vapors" are, or may be, present in the air in quantities sufficient to produce explosive or ignitible mixturesBasics of Explosion Protection INTRODUCTION
