煤系地层裂缝裂隙发育带的预测

The prediction of fractured zone in coal-series strata

介绍三维三分量地震勘探技术在开滦矿业集团钱家营矿四、十采区裂缝预测中的应用.通过三分量地震资料的处理和解释,利用横波双折射现象和快、慢横波在地震记录到达时的时差,对矿区各煤系地层层段的裂缝发育情况做了定量的预测,预测了煤系地层中裂缝发育的统计主方向和发育密度,为矿井生产提供较好的基础资料 .

Introduced the application of 3components and 3dimensional seismic technology on the No4 and No10 working area of Qianjiaying Mine, Kailuan Mine Co.. Through the processing and interpretation of 3components seismic data, we predict the fractured zone, including the density of fracture and arraying direct based on the principle of shear wave split which will induce travelling time delay between quick shear and slow shear.
