Failure characteristics and strength formation mechanism of cement-fly ash based cemented gangue backfill

open access: yesMeitan kexue jishu
In the process of constructional backfilling coal mining (CBCM), the demand for the strength of cemented gangue backfill (CGB) samples varies with different backfill rates. It is planned to adjust the strength of CGB samples by changing the proportion of

Experimental study on the characteristics of fly ash colloid containing XG/HPMC to inhibit coal spontaneous combustion

open access: yesMeikuang Anquan
Fly ash grouting is a common method for mine fire prevention and control. Aiming at the problems of fly ash slurry which is prone to water-loss cracking, poor stability and low fire prevention efficiency, fly ash colloids were prepared by adding high ...

SURFACE MODIFICATION OF FLY ASH FROM ASAM-ASAM COAL POWER PLANT USING STEARIC ACID AS HYDROPHOBIC INORGANIC MATERIAL

open access: yesJurnal Kimia Riset
Abundant coal reserves make this material a substitute fuel choice, especially for industry. The use of coal carries a high risk due to incomplete combustion and produces fly ash products. Fly ash cause pollution and health risks as well as environmental

Optimization of the synthesis conditions of zeolite adsorbents derived from coal fly ash and study on their adsorption performance on benzene

open access: yes能源环境保护
Zeolite adsorbents were synthesized through an alkali fusion-hydrothermal process, using coal fly ash as a raw material. Firstly, the coal fly ash was mixed with sodium hydroxide at a mass ratio of 1∶1.2 and then roasted at 850 ℃ for 2 h to obtain the ...
