| 摘 要： | 以大坝煤矿大量的构造统计资料的依据，应用地质力学方法对矿井的构造进行分析，得出矿井主要构造型式有三种：一是NE向构造带，由NE60°压性构造形迹和NNW向张性构造形迹组成；二是“多”字型构造，由NE10°压扭断层、次级褶皱和NEE向张扭性断层组成；三是压扭性帚状构造，由5条NW-SE向压扭性断层组成，呈向北西突出的弧形。根据矿井构造分布规律，采用“见夹思断”、“右手规则”、“入”字型结构指示法对采掘区的构造进行预测，寻找边角残煤、解释断层交切关系等。

| Abstract: | Based on the abundant structural statistical data of the Daba coalmine, analyzed structures through the use of geomechanic method. Worked out the coalmine have three major structural types： 1. NE structure is composed of NE60o compressoshear structural features and NNW tension structural features; 2. ξ structure is composed of NE10o compresso-shear faults, secondary folds and NEE tenso-shear faults; 3. compresso-shear v structure is composed of 5 NW-SE compresso-shear faults, showing itself an arc protruding NW. According to coalmine structure distribution pattern, predicted structures in production blocks through ＂a parting can indicate a fault＂, ＂right-hand rule＂ and ＂λ type texture designating method＂ to find out leftover remnant coals, interpret intersection between faults. |
