摘要
以山东大学章丘区小冶睦里地区石炭-二叠纪含煤地层采空区为研究对象,采取资料收集、井间地震、钻探验证等方法手段,分析井间地震层析成像技术对采空区解译推断的有效性。结果表明,井间地震层析成像速度反演结果体现为高速分布的区域,推断为基岩完整区域;速度反演结果体现为低速分布的区域,推断为采煤采空区域。经与钻探工程比对,井间地震层析成像技术推断的采空区位置与钻探揭露深度较为吻合,表明井间地震层析成像技术在山东大学章丘区小冶睦里煤矿采空区勘查中具有较高的可行性和实用性,为该地区同类型的采空区勘查提供了参考依据。
Taking the goaf of Carboniferous-Permian coal bearing strata in Xiaoyemuli area in Zhangqiu district in Ji'nan city as the research object,the effectiveness of crosswell seismic tomography technology for goaf interpretation and inference has been analyzed by means of data collection,crosswell seismic and drilling verification.It is showed that the velocity inversion results of crosswell seismic tomography are reflected in the area of high-speed distribution and inferred as the area of complete bedrock.The velocity inversion results are reflected in the area of low-speed distribution and inferred as the mined out area of coal mining.Comparing with the drilling project,the goaf position inferred by the crosswell seismic tomography technology is consistent with the drilling exposure depth.It is indicated that the crosswell seismic tomography technology has high feasibility and practicability in the exploration of coal mine goaf in Xiaoyemuli area in Zhangqiu district in Ji'nan city.It will provide a guidance and basis for the exploration of the same type of goaf in this area.
