槽波地震勘探技术在煤矿灾害探测中的适用性研究

Applicability of Coal Mine Disaster Detecting by In-seam Seismic Survey

为研究槽波地震勘探技术对地应力集中区、瓦斯富集区和奥灰突水风险区探测的适用性,在义马煤矿开展了相关槽波试验,通过原始数据转换、静校正、AGC增益控制、滤波和CT层析成像等,形成槽波波速图,结果显示槽波有可能预测上述三大灾害发生的地点,初步证明该技术可以用于指导矿井防冲工作与防治水工作并对防突工作提供参考。

In order to study the applicability for detecting the area of stress concentration, methane accumulation and water inrush by in-seam seismic survey （ISS）, experiments had been carried out in Yima coal mine. By data conversion, static correction, auto gain control, filtering and computed tomography. Exploration results showed that 3 areas, where above-mentioned disaster happened, could be predicted possibly. The practice has proved that ISS could be applied for guiding rock burst prevention and water prevention and control, and providing reference for methane outburst prevention.
