三维地震勘探方差数据体技术在同发东周窑矿的应用

Application of 3d seismic exploration variance data body technology in Tongfa Dongzhouyao Mine

东周窑井田在巷道掘进以及回采过程中遇到诸多地质问题,仅仅通过钻孔不能把握煤层赋存及构造发育情况。利用方差数据技术处理三维地震勘探获得的数据,能够快速识别整个地震勘探区域的地质构造以及岩层的分布特征。由于方差体数据技术强调数据的不相干性,勘探数据的解释精度及速度得到提高。结合方差体属性的5 m×5 m精细解释,成功准确地预测了西部二盘区运输巷煤层赋存及构造发育情况,为矿井安全高效生产提供了有力依据。

Based on many geological problems in excavation and mining process, coal seam occurrence and structural development couldn＇ t be identified only by drilling. Data of three - dimensional seismic exploration were processed through variance data technique, geological structure of whole seismic exploration area and distribution characteristics of rock formations could be quickly identified. The interpretation accuracy and speed of exploration data were improved due to data technology of variances. The structure and development of coal seam in western area were predicted successfully with the detailed explanation of variate properties of 5 m × 5 m, which provided a strong basis for the safe and emcient production of mine.
