构造控制与瓦斯涌出量分带

Structure Controlling and Gas Pouring Zonation

地质构造与瓦斯分布关系密切,以平煤十矿为例,根据其回采工作面涌出量数据统计,对应所属构造单元,阐述两者相关性,提出横贯矿井内的"y"字形断层组合及其次级褶皱控制回采工作面瓦斯涌出量具有分带特征。矿井根据构造单元共划分4个瓦斯地质单元,由浅至深瓦斯地质单元内回采工作面瓦斯涌出量并非依次线性增加。同时,结合构造地质特征和已发生突出事故结果,对瓦斯赋存及突出事故分布进行初步预测。

According to the actual gas pouring capacity data of each coal face in different structural regions, gas zonation is caused by y-shaped thrust faults and their secondary folds in the SW wing of Likou Syncline, based on analysis of tectonic evolution and structural features. Main gas controlling structure and gas predictions can be achieved,by gas-related parameters statistics, stress analysis on two walls of fault-bend folds, and results of gas accidents occurred.
