干涉成像在双安煤矿采空区探测中的应用

Application of interferometric imaging in Shuangan goaf detection

采空区的探测一直是一项重要研究课题,目前方法很多且各有优势.本文在这里给出了一种新的方法用于采空区探测—干涉成像法.干涉成像是一种被动源定位方法,经济安全,而且观测系统可以任意排列,灵活性较强.在简要介绍干涉成像法基本原理的基础上,研究了其在双安煤矿采空区探测试验的应用效果.结果表明,干涉成像法对采空区定位效果较为显著,有一定的可行性,可以作为采空区探测的一种手段或者辅助手段.

The survey of mined-out area has become an important subject.Currently,there are many feasible methods for locating gob area.this dissertation used the new method,interferometric imaging,to locate gob area.Interferometric imaging belongs to the passive seismic source imaging,it is more economic and flexible.Besides that,using interferometric imaging,there can be random disposition for the layout of locating the buried source.Based on brief introduces the principle of interferometric imaging,We used interferometric imaging to treat the shuangan data about goaf and the application effects of it are analyzed.According to the result,we find that it is feasible to detect the gob area by interferometric imaging,and it can be a means or a supplementary means in coal mining goaf detection.
