绿水洞煤矿区位于华蓥山滑脱褶皱带之华蓥山复式背斜中偏北段，晚二叠世成煤盆地同沉积构造控制了煤层的沉积和分布，华蓥山滑脱构造演化及大巴山逆冲推覆叠加作用使得该区煤层赋存形态复杂化，区内北东向褶皱和断裂导致地层陡倾直立至倒转、层位缺失或重复、煤厚减薄或增厚，同时隐伏小断层发育，对煤层开采影响大，建议开展井下物探工作。

The Lushuidong coalmine area is situated in the Huayingshan composite anticline middle northerly sector within the Huay-ingshan detachment folded zone. Late Permian synsedimentary structures controlled coal seam deposition and distribution. The evolu-tion of Huayingshan detachment structures and Dabashan thrusting nappe superimposition made the complication of coal seam occur-rences in the area. NE folds and faults brought on strata steeply dipping, erect even up to overturn, horizon hiatus or repeat, coal seam thinning or thickening, hidden minor faults well developed. Thereby largely impacted coal mining, thus underground geophysical pros-pecting works have been suggested.
