美國阿拉巴契亞煤田淺埋煤層長壁開采對地下水影響研究:英文 內(nèi)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采并沒有淺埋煤層概念！睹绹⒗推鮼喢禾餃\埋煤層長壁開采對地下水影響研究（英文版）》研究區(qū)域?qū)儆诖嗣禾，位于賓夕法尼亞州與西弗吉尼亞州交界處，雖然埋深較淺575ft（175m），但大部分為基巖，工作面長度達(dá)1430ft（435m），《美國阿拉巴契亞煤田淺埋煤層長壁開采對地下水影響研究（英文版）》以上覆巖層地質(zhì)構(gòu)造與水文地質(zhì)條件進(jìn)行評價、現(xiàn)場觀測、數(shù)值模擬為基礎(chǔ)，采用材料力學(xué)、彈性力學(xué)和損傷力學(xué)等固體力學(xué)理論，較全面與系統(tǒng)地研究了在采動影響下在淺埋深超長工作面條件下上覆巖層移動特點(diǎn)與對地下水流影響，建立了地下水流采動影響的預(yù)測模型，《美國阿拉巴契亞煤田淺埋煤層長壁開采對地下水影響研究（英文版）》為以后我國西部淺埋煤層超長工作面開采提供了實(shí)踐經(jīng)驗(yàn)與理論基礎(chǔ)。
