瓦斯突出危险带的三维地震探测技术

Technology of 3D seismic exploration for gas outburst danger zone

研究了利用三维地震探测瓦斯突出危险带的技术 ,并在淮南潘三矿进行了应用和验证。研究结果表明 :高分辨率三维地震可以探测落差大于 3m的小断层和相应幅度的小褶皱 ,断层和褶皱可以造成构造应力集中、煤体破坏、瓦斯聚集和突出 ,通过对断层破坏和褶皱变形程度的定量评定可以划分瓦斯突出危险带。应用三维地震技术探测瓦斯突出危险带具有广泛的应用前景。

The technology of 3D seismic exploration for gas outburst danger zone was developed and has been applied in Panji No.3 Mine for a trail test. The results showed that the technology can detect fault with over 3 m drop and folds. The fault and fold can cause tectonic stress focus, seam failed, gas accumulation and gas outburst. The quantitative assessment of fault and fold can divide a gas outburst zone. The 3D seismic exploration technology for exploration of gas outburst danger zone will have a wide application outlook.
