摘要
在新景煤矿构造煤变形特征与发育类型分析的基础上,结合井下煤壁煤体结构观测,探讨了构造煤发育的地质模式。研究表明:新景煤矿3号煤层发育有7种类型的构造煤,同时具有7种构造煤发育地质模式。3号煤层夹矸层附近构造变形强化区和古河流冲刷带构造变形强化区常见有揉皱煤、鳞片煤、碎斑煤和碎粒煤等强变形构造煤类型发育,15号煤层整体构造变形较弱,局部正断层构造变形增强区和逆断层挤压强化变形区可造成碎斑煤和碎裂煤的发育。
On the basis of the analysis of the deformation characteristics and development types of structural coal in Xinjing Coal Mine,combined with the observation of coal wall coal structure in underground coal mine,the geological model of structural coal development was discussed.The study showed that there were 7 types of tectonic coal developed in No.3 coal seam of Xinjing Coal Mine and 7 types of geological model of tectonic coal development.The structural deformation intensification zone near the gangue layer in No.3 coal seam and the tectonic deformation strengthening area of the ancient river scour belt are often developed with strong deformation coal types,such as rubbed coal,scaly coal,broken spot coal and crushed coal,and the overall structural deformation of No.15 coal seam was weak.The development of fractured coal and cataclastic coal can be caused by local normal faults,tectonic deformation enhancement zones,and reverse fault extrusion and enhanced deformation zones.
