超化煤矿二_1“三软”煤层瓦斯地质规律研究
|
摘要
运用板块构造理论和区域构造演化理论,研究了新密矿区超化煤矿的矿区、矿井构造演化,构造应力场,构造变形,构造发育,构造控制瓦斯特征;研究了各个不同方向的断裂活动和力学特征,以及滑动构造对煤层变形、破坏而形成构造煤的控制特征。对超化煤矿主采的二1“三软”煤层瓦斯生成、保存条件进行了科学的分析,深入地研究了矿井二1“三软”煤层瓦斯地质规律,从而为有的放矢地治理矿井瓦斯灾害奠定了理论基础。
In this paper,study was conducted on the structural evolution,structural stress field,structural deformation,structural development and the gas characteristics controlled under the structure in the mining district and mine shaft of Chaohua Coal Mine in Xinmi Coal Mining Area according to the theory of plate tectonics and the evolution theory of regional structure;study was also made on the breaking activity and mechanical features in different directions,and the controlled features of the structural coal formed due to coal seam deformation and failure under the action of sliding structure.Analysis was conducted on the gas generation and occurrence conditions of No.2,”three-soft” Seam in Chaohua Mine,and a thorough study was made on the regularity of gas geology of No.21 ”three-soft” Seam,these thus laid a theoretical foundation for the prevention and control of the mine gas disaster.
