东川汤丹铜矿复杂采空区群联合调查技术方法研究及应用

Research and Application of Joint Investigation Technology Method for Complex Goaf Area Groups in Dongchuan Tangdan Copper Mine

复杂采空区群的调查和探测一直属于世界性难题。汤丹铜矿经过开采多年,形成了大量形态不规整的采空区。为查明汤丹铜矿采空区数量、规模及空间结构,通过对国内外采空区探测技术综合研究分析,结合矿山实际需求对东川汤丹矿区开展采空区调查工作。采用了矿产地质调查、工程地质调查、地表现状测绘、地球物理探测、钻探工程验证、三维激光扫描、矿床三维建模等调查技术方法手段,较好地完成了采空区调查工作。同时总结形成地—物—测—采—工多学科联合调查技术方法体系,为今后开展复杂采空区群的调查和探测工作提供了借鉴和理论支撑。

The investigation and detection of complex goaf group been a worldwide problem.After many years of mining,Tongdan Copper Mine has formed a large number of irregular goafs.In order to find out the quantity,scale and spatial structure of goaf in Tangdan Copper Mine,through the comprehensive research and analysis of goaf detection technology at home and abroad,combined with the actual needs of the mine,the investigation of goaf in Dongchuan Tangdan Mine was carried out.By means of mineral geolog⁃ical survey,engineering geological survey,surface surveying and mapping,geophysical exploration,drill⁃ing engineering verification,three-dimensional laser scanning and three-dimensional modeling of ore de⁃posits,the goaf survey is well completed.At the same time,it summarizes the formation of a multidisci⁃plinary joint survey technical method system of ground-object-survey-mining-industry,which provides reference and theoretical support for the investigation and detection of complex goaf group in the future.
