松藻矿区地质构造规律的认识

Geological Structural Pattern Realization in Songzao Mining Area

松藻矿区是国家规划矿区,煤层薄、地质构造复杂、瓦斯灾害严重,分析断层的发育规律,对矿区安全生产意义重大。根据构造运动、构造应力及矿区勘查和井下揭露的地质资料分析认为,矿区北部主构造线走向为南北至北北西向,南部为北东向,在平面分布上形成向北东收敛、向南西撒开的放射状;断层主要集中在松坎河、仙峒河及次一级褶曲轴部附近,断层走向与主构造线方向一致的断层多为逆断层,垂直或斜交主构造线的断层多为正断层;主要褶皱由东向西依次发育有两河口向斜、羊叉滩背斜、大木树向斜和鱼跳背斜。

The Songzao mining area is one of state planned mining areas. The area has thin coal seams, complex geological structures, serious gas calamities, thus to analyze fauh developing pattern has major significance on mining area safety production. Based on analyses of tectonic movement, tectonic stress and mining area exploration, underground disclosed geological data, considered that the north part of the mining area main tectonic line strike is NS to NNW, south part NE, on planar distribution, they are converging northeastward, radial diverging southwestward. Faults are mainly concentrated in Songkan River, Xiandong River and secondary fold axes nearby. If faults have strike identical with main tectonic line, they are mainly reverse faults, if perpendicular or oblique to main tectonic line, mainly normal faults. Main folds from east to west in turn have Lianghekou syncline, Yangchatan anticline, Damushu syncline and Yutiao anticline.
