摘　　要：从胶结充填体在采空区所起的力学作用入手,借助于经验类比法和数学力学模型计算法,得出了能够满足井下采空区所需的胶结充填体强度的要求,为矿山充填配比设计提供了强度依据。同时也分析了暴露宽度与暴露高度对胶结充填体强度的影响关系,揭示具有稳定性的胶结充填体力学强度变化特性。结合安徽某铜矿的工业性试验情况进行了实例分析,从而验证了上述结论的合理性。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.
