摘　　要：马田矿区位于郴耒煤田中部,含煤地层为二叠系上统龙潭组,主采煤层为61和62煤。马田推覆断裂F1对马田矿区的含煤地层起着控制、改造和破坏作用。通过对以往地质资料的分析,认为F1断层向区内深部延展,下盘仍保留有龙潭组上段的主要可采煤层61和62煤,在矿区西部庙嘴岭背斜南端寿福寺附近,煤层埋深相对较浅,可作为资源勘查的重点区域;勘查手段宜先采用地震勘查,寻找煤层埋藏较浅区段,再用钻探验证。The Matian mine area lies in the middle Chenzhou-Leiyang coalfield, main mineable coal seams have Nos.61 and 62. The Matian nappe structure F1 controls, reforms and destructs coal-bearing strata in the mine area. After past geological data analysis, considered that the F~ extents toward into deep part, mineable coal seams Nos.6j and 6., in the Upper Member, Longtan Formation are still preserved in the footwall. Near the Shoufusi village at the south end of Miaozuiling anticline in west part of mine area, buried depth of coal seams is relatively shallower, thus can be the target area of exploration. First of all, the seismic prospecting can be used to find out shallower buried sector of coal seams, then drilling verification.
