槽波地震勘探在李雅庄煤矿构造探测中的应用

Application of Channel Wave Seismic Exploration to Structural Exploration in Liyazhuang Coal Mine

为探明李雅庄煤矿2-612工作面内的隐伏断层及陷落柱展布,保障煤矿安全生产和合理回采,采用槽波地震透射法与反射法对2-612工作面的槽波响应特征进行研究。研究表明:通过槽波能量变化可绘得CT成像图,分辨工作面内与煤厚相当的小构造,并综合已有地质资料和工作面采掘资料,可预测判定断层及陷落柱位置,确定了2-612工作面大、小断层8个,待定异常区域1个。槽波地震勘探技术在李雅庄煤矿取得较好的应用效果,探测结果可作为煤矿安全回采的依据。

For the distribution of buried fault and collapse column in Liyazhuang coal mine 2-612 working face is proved,and the safety production and reasonable mining is ensured. In 2-612 working face,the wave response characteristics are studied by using channel wave seismic transmission method and the reflection method. Research shows that CT imaging map can be drawn by the change of channel wave energy,the same small structure with the same coal thickness can be resolved within the working face. The position of fault and subsided column can be predicted and judged by comprehensive geological data and mining data of working face. Eight faults and one abnormal region are identified in 2-612 working face. Channel wave seismic exploration technology has achieved good application effect in Liyazhuang coal mine. The detection results can be used as the basis for safe mining of coal mine.
