Coal Combustion and Combustion Products

Chinese used coal as early as 1000 BC, while the Greeks and Romans made use of coal before 200 BC. By 1215 AD, trade in coal had started in England. The pioneering uses of coal (e.g., coke, coal tars, gasification), have advanced steadily since the late sixteenth century. Coal combustion technology has been further developed since the late

Mechanical Model of Underground Shaft Coal Pocket and ...

In order to provide a theoretical basis for the design of underground shaft coal pocket and support parameters in coal mines, a mechanical model and a dynamic analysis of the silo wall are established based on the engineering background of Ganhe Coal Mine. The numerical calculation is carried out by using the new model. The back analysis of the silo wall …
