摘　　要：以小庄煤矿为例,深入探讨了煤矿井下主要地质构造背斜和断层附近的应力特征。小庄煤矿位于彬长矿区中部,该地区地质构造复杂,通过对背斜和断层地质进行分析,发现背斜的存在导致了应力在褶皱核附近显著集中,尤其是背斜顶部和两翼过渡区,其中垂直应力值比远离背斜区域的平均应力值高出约15%。此外,背斜的南翼和北翼由于倾角不同,导致应力分布不对称。断层区域的应力测量也显示了类似的高应力集中现象,尤其是在断层两侧,应力值高出周围区域20%以上。通过理论预测与实际应力测量的对比,验证了地应力模型的准确性及其在实际地质工程中的应用局限性,不仅加深了对矿区地应力分布特性的理解,而且为煤矿安全生产中的地质灾害预防和控制提供了科学依据。Taking Xiaozhuang Coal Mine as an example,the stress characteristics near the main geological structures such as anticlines and faults underground were deeply explored.Xiaozhuang Coal Mine is located in the central part of the Binchang mining area,where the geological structure is complex.Through analysis of the geology of the anticline and faults,it is found that the existence of the anticline has led to significant stress concentration near the fold core,especially in the top and transition zones of the anticline,where the vertical stress value is about 15%higher than the average stress value in the distant anticline area.In addition,the south and north wings of the anticline have different inclinations,resulting in asymmetric stress distribution.The stress measurement in the fault zone also showed a similar phenomenon of high stress concentration,especially on both sides of the fault,with stress values more than 20%higher than the surrounding area.By comparing theoretical predictions with actual stress measurements,the accuracy of the geostress model and its limitations in practical geological engineering were verified.This not only deepens the understanding of the distribution characteristics of geostress in mining areas,but also provides a scientific basis for geological disaster prevention and control in coal mine safety production.
