The comparative analysis of detecting anomalous body by radio wave penetration on coal mine working face

摘要

There are some common geological anomaly situations in the process of mining on working faces of mines, such as fault、thin coal layer area and pinch zone.All of these geological anomalies bring various degrees of influence to coal mine fully mechanized mining working face, causing slow progress in mining and worse coal quality.They seriously affect the high production and high efficiency of the mine, even leading to off production of the working face.For detection of geological anomaly on the working face, radio wave penetration method is commonly used, but the effect has always been the focus of mine workers' attention.This paper comprehensively compare the radio wave penetration results on working face of Huainan Coal Mine 1231(1)and the mining confirmation, holding that radio waves penetration has significant characteristics of field intensity attenuation in anomalous section, but for long distance strike fault, it is limited to control and analyze the precision.It should be combined with other exploration methods for fine interpretation.
