摘  要:煤与瓦斯突出灾害是我国煤矿的主要灾害之一,严重阻碍煤矿的安全、高效生产。大多数煤层形成后,经历了多期构造运动的改造,形成了复杂的构造体系。我国大多数煤矿受多重地质构造的影响,造成了煤矿瓦斯地质特征更加复杂。以平顶山矿区为例,通过对矿区构造背景、地质构造特征、矿井分布与地质构造部位关系及不同构造部位矿井的煤与瓦斯突出危险性分析,揭示了地质构造对煤与瓦斯突出灾害具有控制性作用,且受多重地质构造影响的煤层煤与瓦斯突出特征更为复杂,研究成果可指导煤矿瓦斯灾害的防治。Coal and gas outburst is one of the major coal mine disaster that impedes seriously the mine safety and efficient production.After the formation of coal seams in most mining areas in China,they have undergone multi-stage tectonic movement successively,which results in formed a complex structural system.Most coal mines are affected and constrained by multiple geological structures,which makes the geological characteristics of coal mine gas more complex.Taking Pingdingshan mining area as an example,analyzes the structural background,characteristics of geological structure,the relationship between mine distribution and geological structure parts,and the risk of coal and gas outburst in mines with different structural parts,and reveals that the geological structure has a controlling role in coal and gas outburst,and the characteristics of coal and gas outburst affected and constrained by multiple geological structures is more complex.The research results can guide the prevention and control of coal mine gas disaster.
