摘要
矿井地质构造是影响煤矿生产建设最重要的地质条件。本区地质构造条件复杂,小断层较多,严重制约了矿井采掘工作的进行。运用地质统计方法等手段对金源煤矿地质资料进行分析和研究,认为本区构造主要以北北东向的张性正断层为主,褶皱较为宽缓。已发现的断层有111条,断层将井田切割成与断裂构造平行的多个条块,在地层走向上形成阶梯状或地堑、地垒构造。根据该矿地质构造的特征,对其可能引发的地质灾害进行了分析。
The mine geological structure is the major geological condition to impact coalmine production and construction. The geological structure condition in the area is rather complex, many minor faults seriously restricted mine winning and opening. Through measures including geological statistic method carried out geological data analyses and studies in the Jinyuan coalmine, considered that structures in the area are mainly NNE tensional normal faults, folds are broad and gentle. Up to now, 111 faults have found, they dissected the minefield into many strips parallel to faulted structures, along the strata strike formed a series of stepped structures or grabens, horsts. Based on the coalmine geological structure features, possible geologieal hazards have analyzed.
