摘　　要：以石竹山-樟木桥矿区为研究对象,从褶曲、断裂两方面分析研究区构造特征,结合区内的煤层赋存及分布,进一步分析构造变动对煤层赋存的控制作用。研究认为:(1)煤系地层受后期南北向构造侧向挤压,产生紧密褶皱,煤层完好地保存在复向斜中,向斜两翼分别被F31及F2断层、中部受F3正断层切割,破坏了煤层连续性;(2)研究区控煤构造样式为褶皱断裂组合型,断裂和褶皱对煤系的赋存有较大的影响。研究成果对于深入认识该地区煤田构造发育规律,指导煤炭资源评价和勘查具有重要意义。Take the ShiZhushan-ZhangMuqiao mining area as the research object,from the two aspects of fold and fracture to analyze the structural characteristics of the study area,then combined with coal seam occurrence characteristic to further analyze the control effect of structural change on the formation and occurrence of coal seam.The results show that:(1)Strata by late NS-trending tectonic lateral extrusion,produce close fold,coal seam in good fits synclinorium,syncline wings were F31 and F2 fault,central F3 fault cutting,destroy the continuity of coal seam,the east is influenced by the ancient geographical environment,coal seam in sink.(2)The coal controlling structure style in the study area is the combination of thrust fold and the fault and fold have great influence on the occurrence of coal measures.The research results are of great significance for understanding the tectonic development rules of coal field in this region,and guiding the evaluation and exploration of coal resources.
