Experimental results show that ordinary cement can not meet the need of filling engineering in XinSan mine with low purity of SL.
Under the condition of the same collapsed slump about 10~250mm. according to paste filling materials technology requirements, the reasonable proportion satisfying filling engineering requirement can be obtained as follows: ① The concentration of fine aggregate made with the fly ash from Minmetals power plant should be controlled at 72%,the matching requirements are as follows： Cementing material:150 kg/m3;Coal ash:400 kg/m3;Gangue:723 kg/m3;Water:494 kg/m3. ② The concentration of fine aggregate made with the fly ash from MaTou power plant should be controlled at 81%,the matching requirements are as follows： Cementing material:100 kg/m3;Coal ash:400 kg/m3;Gangue:1084 kg/m3;Water:372 kg/m3。
