胶结充填体力学作用机理及稳定性分析

阐述了胶结充填体力学作用的机理,通过工程类比法和理论分析计算法,研究确定了满足安庆铜矿井下采空区所需的胶结充填体强度要求,为矿山充填配比设计提供了强度依据。同时也得出胶结充填体强度与暴露高度和宽度的关系,揭示具有稳定性的胶结充填体力学强度变化特性。

Mechanical Action and Stability Analysis for Cemented Backfill

The mechanics process mechanism of cemented backfill is expatiated in this paper.By engineering analogy and academic analysis method,it gives requirement strength of cemented backfill mass for the underground voids of Anqing Copper Mine,and calculating results can afford strength warranty for mine backfill mix proportion.At the same time it educes the relation of strength of cemented fill mass and exposure height and width,and reveals variety characteristic of mechanics strength of stable cemented fill mass.
