Abstract: There was abundant coal resources in Xindian Mining Area, but the fault structure was developed. In order to effectively exploit the Xindian Mining Area coal resources, based on geological mapping, drilling, well logging and other exploration data, in combination with regional geological data, the distribution feature, dev elopment regularity and its effect on coal mine construction of fault structures were studied. The results showed that fault structure by NE reverse faults were developed in Xindian Mining Area, and the structure framework of three layers of overlapped were formed by three groups NE faults in west, middle and east. The distribution of coal beds were controlled by two groups of NE reverse faults in west and middle. The continuity of coal seam NW-SE was destroyed. The hydrogeological condition and m ining technical condition of coalbed in mining area were complicated. Three blocks suitable for medium mine construction were divided in the whole complicated backgr ound. Single mine construction scale on 0.30 ~ 0.45 Mt was appropriate, could not be too large.
