摘要: Uncontrolled subterranean coal fires, mainly developed through the process of self-ignition, represent a challenging hazard local dimension, but with globalscale distribution. One important effect this spontaneous ignition is surface subsidence. Porosity and particle size fraction particles in deposit, water oxygen play main role. Anina sterile heaps present non-typical situation waste-coal self-ignition. The fine found distributed all over actual urban area, being covered by human activities residential buildings, so that, risk several forms.
