| 摘 要： | 地质构造透明化是我国煤矿智能化开采的基础。随着矿井物探技术的发展，槽波地震勘探备受关注，其中，槽波速度分析是主要处理方法之一。但是，矿用雷管的不确定延迟误差严重影响地震数据初至，如果槽波旅行时拾取出现偏差，极易造成探测结果偏移、误探、漏探。从硬件研发和软件改进两方面开展槽波地震勘探延时校正技术以及延时校正套筒的研发，实现了槽波探测设备与锚杆的对接，可逐炮采集雷管的延迟误差；延时校正流程的改进，实现了逐炮采集到雷管延迟误差在处理软件中的加载和应用。研究应用表明，延时校正技术可有效提高槽波探测准确率，对回采工作面内地质构造的位置圈定和解释具有重要意义。

| Abstract: | The transparency of geologic structure is the basics of intellectualization of coal mine in our country.As mine geophysical prospecting develops，in seam seismic exploration is receiving significant attention，and the velocity analysis of in seam wave is the main treatment method.However，the first arrival of seismic data is severely affected by uncertainty detonator delay error，if the picking of in seam wave′s travel time appear error，the detection results will accurate.The paper was researched delay correction in seam seismic exploration from hardware development and software improvement.The research showed that，the development of delay correction socket could connect in-seam wave detection equipment and bolts，collected detonator delay errors one by one；
the improvement of delay correction flow realized loading of detonator delay errors.In conclusion，the technology of delay correction could improve accuracy of in seam seismic exploration，which was very important to circle and explain the geologic structure in the working face. |
