2011年8月6日14时，临近黄河的韩城禹昌煤矿在11#煤层回采过程中发生底板奥灰水突水，突水通过相邻煤矿采空区，并与8月7日零时5分许冲跨桑树坪煤矿北二车场绕道封闭墙进入斜井280m大巷，很快淹没整个大巷系统造成斜井整体淹井事故。在进行了井上、下水文地质调查、物探、钻探探查和示踪剂测试、水质化验与综合分析研究的基础上，初步确定了突水点与过水通道的区域，结合矿井11#煤层顶、底板、奥灰岩峰峰二段水文地质条件特征，采取了骨料灌注沉积法和松散体注浆加固法，成功隔离了两个矿井之间的水力联系。经过单位吸水率、追排水量、水位变化、残余出水量检验，达到了预期目的，实现了隐蔽突水点及过水通道快速封堵，为矿井全面恢复生产提供了重要保障。
2011年8月6日14時，臨近黃河的韓城禹昌煤礦在11#煤層迴採過程中髮生底闆奧灰水突水，突水通過相鄰煤礦採空區，併與8月7日零時5分許遲跨桑樹坪煤礦北二車場繞道封閉牆進入斜井280m大巷，很快淹沒整箇大巷繫統造成斜井整體淹井事故。在進行瞭井上、下水文地質調查、物探、鑽探探查和示蹤劑測試、水質化驗與綜閤分析研究的基礎上，初步確定瞭突水點與過水通道的區域，結閤礦井11#煤層頂、底闆、奧灰巖峰峰二段水文地質條件特徵，採取瞭骨料灌註沉積法和鬆散體註漿加固法，成功隔離瞭兩箇礦井之間的水力聯繫。經過單位吸水率、追排水量、水位變化、殘餘齣水量檢驗，達到瞭預期目的，實現瞭隱蔽突水點及過水通道快速封堵，為礦井全麵恢複生產提供瞭重要保障。

On 14:00 August 6, 2011, the Yuchang coalmine, Hancheng near the Yellow River happened floor Ordovician limestone wa-ter bursting during the coal No.11 winning. The water bursting passing through neighboring coalmine gob and washed away N2 pitbot-tom of the Sangshuping coalmine by pass blockade wall entered into incline 280m level main roadway about 00:05 August 7, quickly drowned the entire main roadway system causing the whole incline submerged. Based on surface and underground hydrogeological in-vestigation, geophysical prospecting, drilling and tracer detection, water quality testing and comprehensive analysis, initially identified water bursting point and water channel limits;combined with hydrogeological condition characteristics of coal No. 11 roof and floor, Or-dovician Fengfeng Formation second member, using aggregate packing deposition and loose material grouting consolidation, successful-ly isolated hydraulic connection between the two coalmines. Through unit absorption rate, drainage volume, water level variation and re-sidual water charge inspection have reached the desired effect, realized hidden water bursting point and water channel instant sealing and provided principal guarantee for coalmine to resume full production.
