摘　　要：为准确掌握新疆屯宝煤矿WII02040502工作面内多个断层的发育情况,实现安全高效开采,采用透射槽波地质勘探技术进行超前精细探测。本次探测共放炮192个,检波点388个,对采集的地震数据进行宽频滤波、埃里相振幅提取、单炮记录分析、频散分析、能量CT成像等处理。从Love型槽波计算结果图中可看出,该工作面M5含煤模型中槽波的埃里相群速度约800 m/s,频率约140 Hz,煤层中心位置处能量最强。从典型透射槽波频散曲线图中可看出,强能量带呈曲线状分布,基阶模式槽波埃里相频率80~130 Hz,槽波速度700~900 m/s。从槽波能量X、Y、Z分量CT成像图中可看出,该工作面分别存在15、13、15个异常区域。依据透射槽波特征分析及能量CT成像图,共查明测区内存在断层解释14处,其中矫正贯穿工作面断层走向、倾向及延伸共6处,较精确地反应了断层在该工作面的产状及沿倾向和走向方向相对位置,可为后续工作面三维全波形反演成像和地质信息透明化建模提供依据。In order to accurately grasp the development of multiple faults in the WII02040502 working face of Tunbao coal mine in Xinjiang,and achieve safe and efficient mining,advanced and precise exploration is carried out using transmission channel wave geological exploration technology.In this exploration,a total of 192 shots were fired and 388 detection points were used.The collected seismic data were processed through broadband filtering,amplitude extraction of the Airy phase,single shot record analysis,frequency dispersion analysis,and energy CT imaging.From the Love type groove wave calculation result graph,it can be seen that the Airy phase group velocity of the groove wave in the M5 coal bearing model of the working face is about 800 m/s,with frequencies of about 140 Hz,and the energy is strongest at the center of the coal seam.From the dispersion curve of typical transmitted slot waves,it can be seen that the strong energy band is distributed in a curved shape.The fundamental mode slot wave has an Airy phase frequency of 80-130 Hz and a slot wave velocity of 700-900 m/s.From the CT imaging images of the X,Y,and Z components of the slot wave energy,it can be seen that there are 15,13,and 15 abnormal areas in the working face,respectively.Based on the analysis of transmission channel wave characteristics and energy CT imaging,a total of 14 fault interpretations were identified in the measurement area,including 6 corrected faults that run through the working face,reflecting the orientation and extension of the faults more accurately.This can provide a basis for subsequent 3D full waveform inversion imaging and geological information transparency modeling of the working face.
