摘要
为提高工作面回采前对地质构造的控制精度,提出将地面三维地震资料与矿井槽波资料相结合的解释思路。利用地面三维地震数据,初步建立空间构造展布格局,通过对槽波资料的高精度解译,获得较小规模的断层等构造的发育情况,实现对工作面构造从大到小的逐级分析、解释。结果表明,通过综合分析三维地震资料和井下槽波资料,能够大大提高构造探测精度,可达到探测落差大于1/2煤厚的技术要求,为煤矿安全高效开采提供了详实的地质资料保障。
In order to improve the control accuracy of the geological structure before the mining of working face,an interpretation idea combining the ground 3D seismic data with the mine solt wave data is proposed.Using the ground 3D seismic data,the spatial structure distribution pattern was preliminarily established.Through the high-precision interpretation of the slot wave data,the development of small-scale faults and other structures was obtained,and it realizes the step-by-step analysis and interpretation of the working face structure from large to small.The results show that the comprehensive analysis of 3D seismic data and mine slot wave data can greatly improve the structural detection accuracy,and it can meet the technical requirements of detecting fault drop greater than 1/2 coal thickness,and provide detailed geological data guarantee for the safe and efficient mining of coal mines.
