摘要
在煤炭开采中,断层是影响综采机组效率的一个重要因素,它不仅是矿井水的运移通道,而且还是影响安全的一个主要因素。文章以淮北童亭煤矿109采区三维地震勘探为例,基于煤层反射波的突出特征,论述了用地震数据层面属性分析技术识别小断层的方法。研究表明:通过对地震资料进行进一步地震属性优化提取处理,不仅明显地提高了发育于煤层中断层的解释精度,而且大大缩短解释周期。
The fault is an important factor to affect the safety and the efficiency of the comprehensive coal mining,and it may be a migration passage of the water in the shaft.This paper,with 3D seismic exploration of Mining Area 109,Tongting Coal Mine,Huaibei,as the example and based on the outstanding features of the reflected wave in the coal seam,gives a introduction on the method of the application of the seismic data attribute analysis technology to identification of the small fault.It is shown based on the research that further optimum extraction of the seismic attribute from the seismic data can not only improve the precision for the interpretation of the fault developed in the coal seam but also shorten greatly the time taken for the interpretation.
