【摘要】 研究了井田构造的基本特征,并依据勘探和生产揭露资料,分析了井田小构造,特别是小断层的发育特征和规律,以及对煤矿综采生产的影响,探讨了地质构造的形成机制。研究表明,构造分布具有一定的规律性,井田内的水文地质条件受控于地质构造条件,大型断裂导水性较差,内部中小型断裂对矿井突水起控制作用。对煤矿生产具有一定的指导意义。更多还原

【Abstract】 Based on the information from the coal production and the exploration in the mine field, the authors investigate the characteristics of geological structure in Xinglongzhang Coalmine, pay special attention to the small-scaled structures and probe into the formation mechanism of geological structure.The investigation indicates that the structure distribution in the mine field possesses some laws.Hydrologic conditions in the mine field are controlled by geological structure conditions,the transmissibility of the large-scaled fractures are weak,but the small-and medium-scaled structures are the main factors controlling the mine water inrush. The research results have some guidance significance to mine production.更多还原
