非均质和结构性是岩体的渗透特征。渗透结构可以分为壳状渗透结构、脉状渗透结构和层状渗透结构三种基本类型 :壳状渗透结构条件下矿坑涌水强度随深度衰减 ;脉状渗透结构使得矿坑涌水强度随深度衰减幅度小 ;层状渗透结构对矿坑涌水强度的控制作用取决于岩层的组合效果。矿区含水岩体的渗透特征由三种基本渗透结构复合而成。复合的渗透结构使矿区出现多条突水强度随深度衰减曲线 ,多个突水强度峰值
Inhomogeneity and structure are the characteristics of rock mass infiltration. The infiltration structure can be divided into three basic types: the shell-like infiltration structure, the vein-infiltration structure and the layered infiltration structure. The gushing strength of the pit decreases with the depth under the condition of the shell-like infiltration structure. The vein infiltration structure makes the intensity of the gushing water inflow decrease with depth The controlling effect of layered infiltration structure on the gushing strength of mine pit depends on the combination effect of rock strata. The infiltration characteristics of the rocky aquifer in the mining area are composed of three basic infiltration structures. The composite infiltration structure causes multiple water inrush intensity with depth attenuation curve, multiple water inrush intensity peaks
