摘要
由于煤矿巷道空间的限制,矿井瞬变电磁法是煤矿巷道地球物理超前探测常用方法之一,绘制视电阻率断面图之前需要对离散数据进行网格化处理,网格化方法是影响视电阻率断面图效果及后期解释的关键因素之一。Surfer软件是美国Golden软件公司推出的一款优秀的二维、三维图形绘制软件,提供了多种插值方法。基于Surfer软件2013版,以某煤矿巷道瞬变电磁超前探测数据为例,说明不同网格化方法对于矿井瞬变电磁数据的插值效果。
Because of the limitation of coal mine roadway space,mine transient electromagnetic method is one of the commonly used methods for geophysical advance detection in coal mine roadway.Before drawing the apparent resistivity contour plan,it is necessary to mesh the discrete data,and the choice of the meshing method affects the effect of the contour plane and the later interpretation.Surfer software is an excellent 2 D and 3 D graphics rendering software from Golden software,Inc.,which provides a variety of interpolation methods.Based on the 2013 version of Surfer software,take the transient electromagnetic pre-detection data of a coal mine roadway as an example to illustrate the interpolation effect of different gridding methods on mine transient electromagnetic data.
