摘要
提出了优势面的控水机制 ,建立了相应的优势指标和评价准则 .数值模拟结果显示 ,优势断裂具有明显的屏蔽效应 ,它是造成矿井滞后突水的主要原因 .
The mechanism of water hazard occurrence and development has never been revealed in a systematic in the past.In this paper,the mechanism of water transportation controlled by preferred plane has been put forward.Furthermore,the corresponding superior indexes and evaluation criterion have been set up.Numerical simulation reveals that preferred fault has obvious shield effect which cause tardy water irruption during underground mining of coal.
