In China, for the technical guidance on the introduction of water–coal fuel [37,38], the State Center for Coal-Water Suspensions of the Coal Industry was established. In 2001, China consumed more than 2.0 million tons of such suspensions [39,40] per year. Fuel preparation was carried out at eight plants with a capacity of up to 600 thousandChina was the greatest coal producer and consumer, sepa-rately occupying 51.6% and 50.8% for the world’s coal in 2021. However, 754 coal mines in China are gas- and coal-herniated mines, and 48% of the state-owned coal mines are gas-rich mines. Gas hazards are still considered the most severe hazard that is threatening Application of Treatment for Deep Hole Drilling Debris in

Thermal degradation, characterization and kinetic modeling
The thermal degradation and kinetics of coal is a key element for the design of pyrolysis process.In order to optimize the particle size effect on coal conversion and reaction kinetics, this research work elucidates the thermal degradation and reaction kinetics of Indian coal with different particle size (106–150, 212–300, 300–425, 425–600 and Underground coal gasification (UCG) is a promising option for the future use of un-worked coal. UCG permits coal to be gasified in situ within the coal seam, via a matrix of wells. The coal is ignited and air is injected underground to sustain a fire, which is essentially used to “mine” the coal and produce a combustible synthetic gas whichUnderground coal gasification: From fundamentals to

Carbon emissions accounting for China’s coal mining sector
Coal is the primary source of China’s carbon emissions due to the energy structure and its resource endowment. This reality creates enormous pressure and impetus for low-carbon pathways of coal production and consumption.

Gasification of Ultrafine Coal–Water Suspensions SpringerLink
The calculations were carried out for several versions: (1) on condition that the water contained in the suspension entirely reacts with coal carbon; (2) 40% of water reacts with carbon; and (3) various air-to-fuel ratios α = 0.3, 0.4, and 0.5. Calculations at α = 0.3 and α = 0.5 were performed only for coal from the Berezovo mine.Coal pieces up to 1 cm in size were crushed for 2 hours in a machine containing steel balls 10-40 mm in diameter, and then the fragments were sieved through 200-µm cells. The photographs and elemental composition of coal were obtained by a Merlin compact, Zeiss scanning electron microscope (Figure 1, Tables 1 and 2).

Aqueous clay suspensions stabilized by alginate fluid gels for coal
We have developed aqueous clay suspensions stabilized by alginate fluid gels (AFG) for coal spontaneous combustion prevention and control. Specially, this study aimed to characterize the effect of AFG on the microstructure, static and dynamic stability, and coal fire inhibition performances of the prepared AFG-stabilized clay suspensions. The selection of a wheel profile is a topic of great interest as it can affect running performances and wheel wear, which needs to be determined based on the actual operational line. Most existing studies, however, aim to improve running performances or reduce contact forces/wear/rolling contact fatigue (RCF) on curves with ideal radii, with Optimizing wheel profiles and suspensions for railway
