Comprehensive Treatment of Coal Waste Piles with Spontaneous Combustion

Abstract

Coal waste is the inevitable outcome during coal mining and processing and its output is more and more tremendous. The underutilized coal waste accumulates and forms waste pile. Its spontaneous combustion could lead to serious environmental problem, indicating it is particularly important to comprehensively treat the coal waste piles with spontaneous combustion. According to the mechanism and characteristic of coal waste piles with spontaneous combustion, this study classified the treatment in the different periods into diagnosis of spontaneous combustion, extinguishment, fire prevention and vegetation restoration. Furthermore, were viewed the advance in studying comprehensive treatment of coal waste piles with spontaneous combustion and we expected to supply the reference for selecting treatment of coal waste piles with spontaneous combustion.
