摘　　要：通过对象山井田勘探、建井及采掘生产以来的地质构造资料进行整理、统计和作图分析,系统总结了已采区断层构造的发育特征和展布组合规律,并对井田未采区的地质构造进行了预测。结果显示,象山煤矿煤层中的断层构造极为发育,主采煤层中众多的中小型构造具有明显的方向性,其中断层展布方向主要为NW向,其次为近EW向、NE向和近SN向;断层发育具有明显的成带性,在3号煤层中划分出4个构造带组和16个构造带,在这些构造带内,煤层构造较为复杂,对安全开采影响较大,而在这些构造带之间则为煤层构造相对简单的块段。On the basis of reorganization statistics and mapping analysis of geological structure data from exploration, mine building and mining, the author has systematically summarized the development features, combination and distribution regularities of geological structures in mined area, and carried out forecast of geological structures in unmined area in Xiangshan coal mine. The results indicated that faults were very developed in coal seams, great number of middle and small scale faults had evident directivity in main mined seam, the extension direction of faults was mainly NW, secondly nearly EW, NE and SN. The development of faults had evident zonation. Geological structures in seam 3 have been divided into 4 structure belt groups and 16 structure belts. In these structure belts, coal seams were complex structurally, which has serious impact on safe mining, while between these belts coal seam was relatively simple in structure.
