Abstract: Based on the mechanical analysis of the cemented fill body in the mined-out are，and by the analogy of experience and mechanical model of mathematical calculation，the strength requirement of cemented fill body for the underground mined-out area were put forward，providing the strength warranty for mix proportion design of mine fill bodyMeanwhile，the effect of explored wide and height on strength of cemented fill body was analyzed，and the variety characteristics of mechanics strength of stability cemented fill body were revealed This conclusion above has been proved to be reasonable in combination with the industrial experiment result in a copper mine in Anhui Province
