ajst-16296	Qi, Jianing	Orthogonal Experimental Study on the Ratio of Similar Materials of Coal Body	2024	7	.pdf	application/pdf	5108	226	60	The orthogonal test method of four factors (bone glue ratio, aggregate ratio, rubber ratio, water mixing rate) and three levels was used to obtain the physical and mechanical parameters such as density, uniaxial compressive strength, elastic modulus, cohesion, internal friction angle and tensile strength of coal similar materials. The range analysis method was used to obtain the key influencing factors and variation rules of the physical and mechanical properties of coal similar materials.	cache/ajst-16296.pdf	txt/ajst-16296.txt
