摘　　要：新店矿区煤炭资源丰富，但断裂构造较为发育，为了能有效开发区内的煤炭资源，以矿区内填图、钻探、测井等勘探资料为基础，结合区域地质资料，对区内的断裂构造分布特征、发育规律及其对煤矿建设的影响等方面进行了研究。研究表明：新店矿区以NE向逆断层为主的断裂构造发育，由西部、中部及东部3组NE向断层形成区内三层叠置的构造格局；西部、中部的两组NE向逆断层控制了煤层的展布，破坏了煤层NW—SE向的连续性；断裂构造使矿区内煤矿床水文地质条件、开采技术条件变得复杂；在构造总体复杂的背景下，划分出3个适宜矿井建设的中等构造区块，单矿井建设规模以30万～45万t为宜．不能过大。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, development 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 mining technical condition of coalbed in mining area were complicated. Three blocks suitable for medium mine construction were divided in the whole complicated background. Single mine construction scale on 0. 30-0. 45 Mt was appropriate,could not be too large.
