地震勘探技术在裴沟矿31采区的应用
|
摘要
在山区地震勘探中,由于复杂多变的岩性及地表的剧烈起伏影响地震成像的品质,本文以裴沟矿井31采区为例,首先在数据采集阶段针对不同地表条件采用不同设备成孔,保证原始数据质量;其次在资料处理阶段通过"两步"静校正方法解决山区高程及岩性变化引起的成像问题,获得高质量的处理成果。经过矿井生产的初步验证可知,所采用的技术手段正确,所取得的地质成果精度较高。
The quality of seismic imaging is great affected by the complex lithology and salient relief surface of the mountainous area.This paper takes the Peigou coal mine 31 mining area as a study example.Firstly,different equipment for boring hole in the data acquisition stage under different surface conditions is adopted to ensure the quality of the original data.Secondly,a"two step"static correction method is used to solve the imaging problem in the stage of processing data that causing by the change of altitude and lithology.Through the above measures,high quality results are obtained.Preliminary validation of the mine production shows that the method is correct,and its accuracy is good.
