【摘要】 煤层工作面内存在诸多影响安全生产的地质因素,利用层析成像技术可以进一步查明其速度分布特征并进行地质异常体特征解释。本文通过构建工作面测试模型,利用模型试验确立地震波CT探测技术方法、观测系统布置、数据采集参数、数据处理及地质解释等系统内容。现场探测工程实践结果表明:地震波CT成像精度和分辨率能够满足现场生产技术要求,可对矿井工作面地质异常体进行有效探查。更多还原

【Abstract】 There are many geological factors that affect the safety production in coal seam workface.The geological anomalies characteristic can be explained according to the velocity distribution of coal seam revealed by the tomography techniques.By building working face test model,using model tests to establish the system contents such as CT detection technology methods of seismic waves,observing system layout,data acquisition parameters,data processing and geological interpretation.The practical results of the site exploration project shows that the CT imaging accuracy and resolution of the seismic waves can meet the on-site production and technical requirements.And the geological anomalies body in the mine workface can be tested and distinguished effectively.更多还原
