摘　　要：老窑巷道一直是威胁煤矿安全生产的重要隐患,三维地震勘探技术是有效的探测手段。为了提高三维地震勘探技术对于老窑巷道识别能力,将最大似然体属性技术应用到三维地震巷道解释过程中,通过其对裂缝及缝洞“反应灵敏”的特性,增强了地震解释技术在巷道识别方面的分辨能力。本文将最大似然体属性技术运用到荆宝煤业三维地震资料精细巷道解释中,通过属性异常特征,推断出未知的老窑巷道的位置及边界。通过与已知资料对比验证,表明了此属性技术在煤田三维地震勘探老窑巷道解释的可行性与优越性。Old roadway has always been an important hidden danger that threatens coal mine safety production.3D seismic exploration technology is an effective detection method.In order to improve the ability of 3D seismic exploration technology to identify old kiln roadways,the maximum likelihood volume attribute technology is applied to 3D seismic roadway interpretation.In the process,through its sensitive characteristics to cracks and fractures and caves,the resolution capability of seismic interpretation technology in roadway identification is enhanced.In this paper,the maximum likelihood volume attribute technology was applied to the interpretation of the 3D seismic data of a mine in Shanxi Province,and the location and boundary of the unknown old kiln roadway can be inferred through the attribute anomaly characteristics.Through comparison and verification with known data,the feasibility and superiority of this attribute technology in the interpretation of old kiln tunnels in coalfield 3D seismic exploration were fully demonstrated.
