中文摘要:

本文以盘江矿区为研究对象，系统厘定了矿区内主要控煤构造(包括断层与褶皱)的展布特征、组合规律及其空间配置关系，深入探讨了其形成的构造动力学背景与成因机制。研究表明:依据构造边界断裂及沉积特征的差异性，可将矿区划分为鸡场坪断褶带、盘县断褶带及兴义穹盆构造变形区三个一级构造单元。构造线主体呈北西向与北东向展布，其中北西向断裂常导致煤层连续性中断，而北东向褶皱则主导煤厚空间变化。在构造成因方面，燕山期近南北向挤压应力场主导了区内逆冲推覆体系及宽缓褶皱的发育；喜马拉雅期走滑作用则对早期构造形迹产生了显著的叠加改造效应。基于含煤构造单元的划分结果，6个次级单元中盘关向斜单元的煤层稳定性最佳，而土城单元因断层密集切割导致煤炭资源呈高度分割状态。通过对矿区构造特征分析，对有效矿区总体规划、煤炭资源的开发利用具有一定的指导意义。

英文摘要:

This paper takes the Panjiang mining area as the research object，systematically clarifying the distribution characteristics，combination patterns，and spatial configuration relationships of the main coal-controlling structures(including faults and folds)within the mining areaIt delves into the tectonic dynamics background and genetic mechanisms of their formationThe research indicates that based on the differences in structural boundary faults and sedimentary characteristics，the mining area can be divided into three primary tectonic units:the Jichangping fault-fold belt，the Panxian fault-fold belt，and the Xingyi dome-basin structural deformation zoneThe main structural lines extend in a northwest-southeast and northeast-southwest direction，with northwest-trending faults often causing disruptions in coal seam continuity，while northeast-trending folds dominate the spatial variation of coal thicknessIn terms of tectonic genesis，the near-south-north compressional stress field during the Yanshanian period dominated the development of the thrust nappe system and broad，gentle folds in the area；the Himalayan strike-slip movement had a significant superimposed transformation effect on early tectonic featuresBased on the division results of coal-bearing tectonic units，among the six secondary units，the Panguan syncline unit exhibits the best coal seam stability，while the Tucheng unit is highly fragmented due to dense fault cuttingThe analysis of the structural characteristics of the mining area provides certain guidance for effective overall planning of the mining area and the development and utilization of coal resources
