摘要: 运用板块构造和地质动力区划理论,研究了平顶山矿区地形地貌和构造演化特征,得出了平顶山矿区地质构造的形成机制和空间分布特征。研究表明,平顶山矿区多次受秦岭造山带由南向北的挤压、剪切作用,形成了以郏县正断层、襄郏正断层、鲁叶正断层为界的四周凹陷带。平顶山矿区中部凸起,全局俯视呈“N”字形地貌,具备发生煤与瓦斯突出等矿井动力灾害的构造环境。利用地质动力区划方法,划分的Ⅲ级活动断裂和Ⅳ级活动断裂,从区域性的尺度上控制了井田煤与瓦斯突出的宏观分布特征,Ⅴ级活动断裂决定了煤与瓦斯突出的局部分布特征。对十二矿井田划分了4个构造分区,控制着十二矿煤与瓦斯突出动力灾害的发生。

Abstract: The topography and geomorphology and tectonic evolution characteristics in Pingdingshan mining area were studied under plate tectonics and geo-dynamic division theory to obtain the formation mechanism and spatial distribution characteristic. The results showed that the Pingdingshan mining area is subjected to the south-to-north downthrust and collision by Qinling orogenic belt, and thus the depression belt formed, bordered by Jiaxian, Xiangjia and Luye normal faults. The middle uplift and N font geomorphology in Pingdingshan mining area have structure environment to cause mine dynamic disasters such as coal and gas outburst. The III level and IV level active faults divided by geo-dynamic division controlled the macro-distribution of coal and gas outburst, and the V level active faults determined the local distribution characteristics. The mine No.12 was divided into four tectonic divisions, which controlled coal and gas outburst occurrence.

Key words: coal and gas outburst, geo-dynamic division, structure environment, active faults
