水城矿区煤与瓦斯突出的构造控制特征

    Structural Control Features of Coal and Gas Outburst in Shuicheng Mining Area

    • 摘要: 为了研究水城矿区地质构造对煤与瓦斯突出的控制特征,在分析矿区区域构造特征和煤与瓦斯突出特点的基础上,系统阐述了矿区断层、层滑构造、褶曲、软分层等构造类型对突出的影响作用。结果表明,矿区断层及其组合、层滑构造、软分层、断层转折褶皱等为瓦斯局部积聚提供了场所,并通过控制煤厚变化、软分层、煤体破坏类型等地质特征控制了地应力、瓦斯压力、煤体力学性质等因素的分布,从而控制了煤与瓦斯突出的区域分布特征。

       

      Abstract: In order to study geological structure control features of coal and gas outburst in Shuicheng Mining Area, on the basis of regional structure features and coal and gas outburst characteristics, we systematically expound the influence of fault, gliding structure, folds, and soft layered structure type on coal and gas outburst. The results show that faults and combinations, gliding structure, soft layering, fault-bend fold provide a place for the gas accumulation, and control distribution of the stress, gas pressure, the physical properties of coal and other factors by controlling coal thickness changes, soft layering, coal damage types and others to control the regional distribution of coal and gas outburst.
