內容簡介

美國東部的阿巴拉契亞煤田(Appalachia Coalfield)大部分為淺埋煤層,但在美國地下長壁開採並沒有淺埋煤層概念。《美國阿拉巴契亞煤田淺埋煤層長壁開採對地下水影響研究(英文版)》研究區域屬於此煤田,位於賓夕法尼亞州與西維吉尼亞州交界處,雖然埋深較淺575ft(175m),但大部分為基岩,工作面長度達1430ft(435m),《美國阿拉巴契亞煤田淺埋煤層長壁開採對地下水影響研究(英文版)》以上覆岩層地質構造與水文地質條件進行評價、現場觀測、數值模擬為基礎,採用材料力學、彈性力學和損傷力學等固體力學理論,較全面與系統地研究了在采動影響下在淺埋深超長工作麵條件下上覆岩層移動特點與對地下水流影響,建立了地下水流采動影響的預測模型,《美國阿拉巴契亞煤田淺埋煤層長壁開採對地下水影響研究(英文版)》為以後我國西部淺埋煤層超長工作面開採提供了實踐經驗與理論基礎。
