某煤矿地质构造控制机理探析

The Elementary Analysis of Geological Structure Control Mechanism on a Coal Mine

根据某煤矿的断层、褶皱等主要构造分布特征,分析该矿井地质构造的分布发育特征。对照该镇矿区地质构造发展,并结合区域构造演化史,分析了矿区构造应力场特征和形成机制,讨论了周期时间。结果显示:矿区构造呈近南北向东倾斜的总趋势,单斜构造,地层扭曲的方向大致沿走向自北向南;该矿区构造主要经历了三期地质构造运动,即印支期的运动、燕山期的运动和喜马拉雅期的运动,其中燕山运动起到承上启下的作用。

According to the distribution characteristics, main tectonic faults and folds and distribution characteristics of some coal mine, this paper analyzes its geological structure development. With the geological structure of this mine, the history of regional tectonic evolution, the tectonic stress field characteristics and formation mechanism, this paper discusses the cycle time. The results showed that the tectonic is the general trend of North-South East dipping monocline strata, twisted roughly along the strike direction from north to South; Suntuan mine construction mainly experienced three tectonic movement period, Indosinian movement, Yanshan movement, and the period of Himalaya movement, the Yanshan movement plays a connecting role.
