可控源音频大地电磁法在奥灰岩溶富水性探测的应用

Application of controlled source audio magnetotelluric method in the detection of water abundance in Ordovician limestone karst

可控源音频大地电磁法因施工方法简便、受地形影响小、勘探深度大等特点已被广泛应用在煤炭深部水害探测中。本文以山西北部塔山矿的奥灰岩溶富水性探测为例,介绍了可控源音频大地电磁法施工参数的选择、数据的处理等关键技术,以及数据的解释方法及应用效果,肯定了这一技术在煤矿深部水害探测中的实用性和进步性。

Controlled source audio frequency magnetotelluric method has been widely used in deep coal water admage detection because of its simple construction method, little influence by terrain and large exploration depth. Taking the detection of Ordovician limestone karst water abundance in a mine in northern Shanxi as an example, this paper introduced the key technologies such as the selection of construction parameters and data processing of controlled source audio magnetotelluric method, the interpretation method and application effect of data, and affirmed the practicability and progress of this technology in the detection of deep water damage in coal mine.
