摘要
采用反映煤体结构破坏程度的若干宏观与测试参数,研究了石嘴山一矿井田主采三层煤的煤体结构变化特征。揭示出三层煤体结构垂向变化的分层性主要受石嘴山向斜中和面所控制;煤体结构横向分区性主要受北西向缓波状褶皱所控制。研究还表明,三层煤煤岩组分的构成也对煤体结构类型的发育有一定影响。
By means of some parameters that reflect breaking strength of coal body structure, changing features of coal body structure at No.3 coal bed of No.1 mine in Shizuishan Mine Area are studied. The investigation shows that the vertical stratification of coal body structure mainly results from the natural plane of Shizuishan syncline and that the transversal zoning of coal body structure is mainly due to NW direction folds. Meanwhile, the research also shows that the macerals of No.3 coal bed exert some influence on coal body structure types too.
