Analysis on Explosion Characteristics of Coal Gangue Hills

Article Preview

Abstract:

In the process of the coal gangue hill explosion, a lot of harmful gases can be released, which seriously pollutes the atmospheric environment and is harmful to people’s health; meanwhile, equipments and the surrounding buildings can also be destroyed, which brings huge economic losses and casualties. In addition, social problems caused by coal gangue hills will become a thorny problem for coal enterprises. Therefore, the influencing factors on the coal gangue hill explosion, the explosion characteristics and laws, and the spontaneous combustion process of the coal gangue hill are analyzed; the coal gangue hill explosion are discussed from the arch shell theory, the bottom air leakage and oxygen supply, rainfall, detonating gas explosion, and chain reaction; the conditions, influencing factors and characteristics of the coal gangue hill explosion are obtained.
