| 摘 要： | 在系统收集水文地质资料的基础上,运用"大井法"和水文地质比拟法对开采16煤的涌水量进行了预测,利用突水系数法,对八采区16煤底板奥灰突水危险性进行了评价,得出了突水系数分区图。经综合分析对比,采用大井法的预测结果:即开采16煤正常涌水量为482m3/h,最大涌水量为540m3/h;奥灰突水量初期为1 083～10 640m3/h,一般为660～4470m3/h;如对奥灰采取疏排降压方案,疏降排水量预计为770m3/h。此结果可作为矿井回采阶段防治水设计的参考。

| Abstract: | Based on hydrogeological data systematic collection,to use the virtual large diameter well method and hydrogeological analogy method predicted No.16 coal seam water inflow during mining,and assessed No.16 coal seam floor Ordovician limestone water bursting hazard in No.8 winning district through water bursting coefficient method,finally mapped out water bursting coefficient partition map.After comprehensive comparative analysis,the predicted results from virtual large diameter well method are used: normal w... |
