天湖山矿区官殊矿井小构造发育特征及其控煤作用

Development Characteristics and Coal-control Laws of Small Structures of Guanshu Mine in Tianhushan Mining Area

为研究官殊矿井小构造发育特征和煤层赋存规律及其关系,在前人研究的基础上,通过对该矿井的现场测量资料的统计和分析,结合应力分析法等综合研究表明:该矿小构造主要有高角度小型逆断层、不协调小褶皱、层间滑动构造,牵引构造等基本类型;小构造控制煤层的赋存,影响煤层的可采性,具有明显的方向性、组合性、伴生性等特征。

In order to study the development characteristics of small structures and the occurrence laws of coal seam and its relationship at Guanshu Mine, on the basis of previous studies, by the statistics and analysis on the field measured data of mine, combined with comprehensive study of stress analysis method, a comprehensive study was reached. The study shows that there are mainly high angle miniature reverse faults, uncoordinated small folds, interlayer-gliding structures, drag structures and other basic types in this mine. The small structures control the occurrence of coal seams, which affects the admissibility of coal seams, with obvious characteristics of direction, combination and companion.
