摘要
从收集整理资料入手,利用地质力学观点,阐述了舒兰街煤矿的构造型式与构造特征,即构造型式为一入字型构造,主要特征是分支断裂越靠近主干断裂落差越大,远离主干断层落差逐渐变小直至尖灭,断层也都为压扭性高角度正断层,断层面(带)断层泥发育,有糜棱岩化、硅化现象,紧闭程度高,具有隔水性。
Starting from the collected data,using the geological mechanics viewpoint,expounds the structural type and structural features of Shulan Street coal mine,which is a λ-type structure.Main feature is that the branch fracture fall greater when it closer to the main fracture,while fall smaller until wedge out away from the main fault,faults are compressoshear high-angle normal fault,fault gouge developed in the fault surface（zone）,with mylonitization,silicified phenomenon,tight degree high,with water-resisting property.
