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。
Songzao mining area is a national planning mining area, the coal seam is thin, the geological structure is complicated and the gas disaster is serious. The analysis of the fault’s development rule is of great significance to the mine safety production. According to the tectonic movement, tectonic stress and geological data of mine exploration and underground exposure, it is considered that the main tectonic line in the northern part of the mining area is north-south to north-north-west direction, the south is northeastward and the distribution is northeast in plane distribution, The faults are mainly located in the vicinity of the Songkan River, Xian-Juan River and the second order fold axis. Faults that are similar in direction to the main tectonic line are mostly reverse faults and faults with vertical or oblique main structural lines are mostly Normal faults. The main folds developed from east to west are Lianghekou syncline, Yangcadan anticline, Dalushu syncline and fish jump anticline.
