三维地震动态解释技术在防治煤矿突水中的应用

Application of 3D Seismic Dynamic Interpretation Technique in Preventing Coal Water Inrush

煤矿三维地震动态解释技术实现了三维地震信息随煤矿生产进行全程动态解释,改变了传统的三维地震解释模式,能够查明煤层中的断层或其它构造分布.利用该项技术对邱集煤矿三维地震数据体进行了分析研究,确定了导水陷落柱的空间位置、边界和大小,为封堵导水通道提供了有力的地质依据.研究表明:利用三维地震信息可以从平面和立体角度研究地层的构造和岩性变化,从而对水文地质异常做出判断,为防治水提供决策依据.

3D seismic dynamic interpretation technique can detect fault and other structures in coal seams, and realize 3D seismic dynamic interpretation with mining production all the time, which modified the traditional 3D seismic interpretation model. Using this technique, we studied 3D seismic data in Qiuji coal mine and determined the space location, boundary, and size of the subsided column, which provided a strong geological basis for blocking up water conducting channel. The results show that 3D seismic data can be used to study structure and lithology variation from both plane and space, to recognize hydrological abnormal, and to provide scientific basis for preventing water inrush.
