淮南煤田罗园井田构造是以阜凤逆冲推覆断层为主要断层组成的逆冲推覆构造系统。针对推覆体内含煤地层急倾斜、倒转以及总体呈“L”形构造形态特征，在二维地震勘查手段效果不理想的情况下，根据构造发育特征选择以钻探为主，布置了垂直钻孔、定向斜孔、分叉孔，并结合测井、采样测试等手段，取得了良好的地质效果。
淮南煤田囉園井田構造是以阜鳳逆遲推覆斷層為主要斷層組成的逆遲推覆構造繫統。針對推覆體內含煤地層急傾斜、倒轉以及總體呈“L”形構造形態特徵，在二維地震勘查手段效果不理想的情況下，根據構造髮育特徵選擇以鑽探為主，佈置瞭垂直鑽孔、定嚮斜孔、分扠孔，併結閤測井、採樣測試等手段，取得瞭良好的地質效果。

Structure in the Luoyuan minefield, Huainan coalfield is a thrusting nappe structure system taking the Fuyang-Fentai thrust-ing nappe as the main fault. In allusion to coal-bearing strata in the nappe characterized by steeply dipping, overturned and present“L”shaped structural forms as a whole. In view of unsatisfactory 2D seismic prospecting effects, according to structural development characteristics choosing drilling dominated (including straight, directional inclined and branching boreholes) combined with well log-ging, sampling and testing means, thus satisfied geological effects have been made.
