复杂条件下金属矿山采空区三维地震探测研究

Research on 3D Seismic Exploration of Metal Mine Goaf under Complex Conditions

矿山采空区的存在,对采矿人员和设备来说是巨大的安全隐患,因此查明采空区的分布十分必要。三维地震探测技术具有很高的空间分辨率,应用到该技术勘测大宝山多金属矿采空区。指出了在复杂地质条件下开展三维地震采空区探测的过程中,从野外数据采集、数据处理到最终解释成果等各个环节所存在的难点,通过对这些难点的分析研究,给出了针对性的应对措施,取得了对采空区的存在和位置探测的良好效果,具有很高的应用指导意义。

The existence of mined-out areas in mines is a huge potential safety hazard for miners and equipment, so it is necessary to find out the distribution of mined-out areas. Since three-dimensional seismic exploration technology has high spatial resolution, this paper applies this technology to the exploration project of Dabaoshan polymetallic mine goaf. It points out the difficulties existing in the field data acquisition, data processing and final interpretation results in the process of three-dimensional seismic goaf detection under complex geological conditions. Through the analysis and research of these difficulties this paper gives the corresponding measures, not only achieving a good survey result for the existence and location prediction of goaf, but also obtaining a preferable direction to the application.
