| Abstract: | Physical and mechanical properties of paste filling materials have an important impact on supporting of filling body of coal mine.Test was made to find out the relationship of mechanical parameters of paste filling material such as uniaxial compressive strength,elastic modulus,internal friction angle,cohesion and curing age as well as cementing material consumption,dosage of fly ash;the relationship between the compressive strength and elastic modulus.The results of the study have certain reference to the design of reasonable material ratio for different technological requirements of coal mine,and it has gotten verification in Zhucun Mine Project. |
