22) Radioelement existing in domestic coal beds is discharged into atmosphere, solid and water environment via medium of smoke coal ash and slag etc.

23) This code is not applicable to building mortar and powdered coal ash used as admixture carrier.

24) Ceramic ecological paver was investigated with solid castoff such as graphite gangue coal ash and coal stone.

25) The paper introduces the methods of making basic Aluminium Chloride from coal ash, and also studies the main factors of making process.

26) Described the actuality and development of the research of the coal ash fusibility.

27) The effect of different fillers such as hollow glass microsphere, pulverous coal ash and foam polymer on water insertion loss of sound isolation rubber material were studied.

28) This paper introduces briefly the principle of the telemetering system for coal ash and gas explosion experimental tunnel and then make an exhaustive analysis of transmission errors of the system.
