摘要
针对挑水河磷矿的实际情况,采用条带充填开采方法。运用两区约束理论及有效区域理论,推导了条带充填开采胶结充填体强度的计算公式。通过工程类比法及理论分析计算,确定了采空区胶结充填体的强度。
The strip-filling mining method is introduced in the light of the actual conditions of Tiaoshuihe Phosphate Mine. The formula for calculating the strength of cemented fill in strip-filling mining is derived based on the theory of two-zone constraints and the effective region theory and the strength of cemented fill in mined-out area is determined by the engineering analogy method and the theoretical analysis method.
