工作面内异常体无线电波CT成像效果分析

Effect analysis on the radio wave CT imaging for the geology abnormal body in the working face of mine

矿井工作面内地质异常体对安全高效生产影响较大,利用无线电波CT成像技术可以有效获得异常体的相对位置及特征,为工作面回采方案制定提供技术指导。论文结合矿井工作面地质条件探查结果,讨论其方法技术特点及其应用效果,其中对与巷道走向夹角大的地质异常体分辨能力强,而对走向延展长的地质异常体判断能力有限,需要结合多种方法综合探查与分析。

The geology abnormal body in the working face of mine has larger influence on the safety and efficient production. The relative location and characteristics of abnormal body can be effective gained by the radio wave penetration CT method,and its detecting results can provide reference for the technical measure decision of the working face mining. In the article, combining with the exploring practice results for the geology condition of mine working face the technical feature and its penetrating and detecting effect by the radio wave CT imaging are discussed. Among the analysis results this method has high resolving power for the geology abnormal body with large included angle and the laneway trend. It is limited to judge the geology abnormal body with long trend extension in the working face,and the comprehensive detection and analysis using multiple methods must be cornbined in the production.
