摘　　要：利用槽波频散特性反演矿区煤系地质构造是一项重要工作,但是槽波传播过程中,地质情况变化复杂,单频或窄带滤波难以兼顾槽波群速度的变化和不同接收点的槽波能量,研究矿区煤系地质构造勘查中的槽波和CT成像联合探测技术。分析了槽波雷达探测技术以及对地质勘查的作用,槽波雷达探测技术凭借波阻抗界面采集煤矿周围的地质相关数据,再实施频散分析以及重构CT成像处理。整合全部勘查数据,分析处理后的资料,实现矿区煤系地质构造勘查。采用SCT槽波数据处理软件进行实验,实验结果表明,将槽波地震联合探测方法引入矿区某矿1223工作面,综合利用透射槽波与反射CT图像重构成果精细解释2条断层在工作面内的展布位置及影响范围,经回采验证,2条断层的解释位置准确,应用效果较理想。Inverting the geological structure of coal measures in mining areas using the dispersion characteristics of slot waves is an important work.However,during the propagation process of slot waves,the geological conditions change complex,and single frequency or narrowband filtering is difficult to balance the changes in slot wave group velocity and slot wave energy at different receiving points.Therefore,the joint detection technology of slot waves and CT imaging in the exploration of coal measures geological structure in mining areas is studied.Analyzing the role of slot wave radar detection technology and its assistance in geological exploration,slot wave radar detection technology collects geological related data around coal mines through wave impedance interfaces,and then performs frequency dispersion analysis and reconstructed CT imaging processing.Integrating all the exploration data,analyzing the processed data to realize the geological structure exploration of coal system in mining area.The experiment was conducted using SCT slot wave data processing software.The experimental results showed that the slot wave seismic joint detection method was introduced into No.1223 working face of a certain mine in the mining area,and the transmission slot wave and reflection CT image reconstruction results were comprehensively used to explain the distribution position and influence range of two faults in the working face.After mining verification,the interpretation position of the two faults was accurate,and the application effect was ideal.
