不同岩层组合对导水裂隙带发育高度的影响

The Influence of Different Strata Combinations on Water-flowing Fractured Zone (WFZ)'s Height

摘要: 导水裂隙带发育高度是矿山研究的重要内容,从不同岩性岩层破坏特征出发,结合岩层承载能力及变形能力分析,提出了一种预计导水裂隙带高度的理论分析力学模型,并以此模型进一步分析了不同岩性岩层组合对导水裂隙带发育高度的影响。再结合数值分析软件RFPA模拟了不同岩性岩层组合下覆岩裂隙动态发育,取得与理论分析一致的结论。

Abstract: Water-flowing Fractured Zone(WFZ)'s Height is an important research content of mining.Based on the features of rock failure,combining with analysis of deformability and bearing capacity,a mechanical model prediction WFZ's height was given in this paper.By which the influence of different strata combinations on WFZ's Height was analysed.Fracture evolution trending under different strata combinations was simulated by RFPA numerical analysis software,which consistented with conclusions of theoretical analysis.
