摘要
选取17个影响因素建立了具有层次结构的底板突水危险性评价指标体系,应用层次分析法确定各影响因素权重及总指标综合权重,采用降半梯形分布函数和线性插值法分别确定定量评价指标和定性指标的隶属度,最终建立基于层次分析法和模糊综合评判法的底板突水危险性评价模型。应用表明:该模型能够定量化反映出A工作面底板突水危险性程度,可以为防治底板水害提供科学可靠的理论依据。
Selected 17 factors and established the hierarchical structure of the water inrush risk evaluation index system, and used AHP to determine the weight factors and the total index of comprehensive weight, the lower semi trapezoidal distribution function and linear interpolation method were used to determine the membership degree of quantitative evaluation and qualitative indicators, finally we established the analytic hierarchy process and fuzzy comprehensive evaluation method of water inrush risk evaluation model. The application shows that this model can quantitatively reflect the risk degree of floor water inrush in a working face, and it can provide scientific and reliable theoretical basis for preventing floor water damage.
