Coal has been a major global resource for at least the past 250 years. The major waste
product of coal mining is waste rock, which is stored in dumps of various sizes. Although the …

The process of spontaneous combustion of coal and coal waste gobs including emitted
gases, condensation of inorganic and organic species in vents, and leachable potential are …

The co-spontaneous combustion of coal and gangue widely exists in the world and
threatens the safety of coal mines. In this paper, the microstructure of coal and gangue were …

To explore the thermal behavior and hazard during the spontaneous combustion fires
(SCFs) of coal and coal gangue (CG), the characteristics of heat release and thermal …

This study investigated the combustion properties of coal gangue (CG) from the Gongwusu
coal mine in northern China. Three CG samples collected from various parts of the …

A range of carbon nanoparticles, agglomerates and mineral phases have been identified in
burning coal waste pile materials from the Douro Coalfield of Portugal, as a basis for …

A self-heating intensity index (SHII) based on the highest (pixel max.) and lowest (pixel min.)
values taken from satellite thermal maps of burning coal waste dumps are proposed. The …

Consequent to the escalations in global energy consumption, the biomass-to-fuel processes
are increasingly becoming important areas to the energy industry and policy makers. In this …

In the process of coal gangue surface accumulation and underground filling disposal, the
heavy metals contained in coal gangue will inevitably precipitate out and migrate, which will …

In order to further investigate the spontaneous combustion characteristics of coal gangue
(CG) hills, this paper explored the potential connection between the spontaneous …
