摘要
为了准确有效地预测预报掘进迎头前方采空区,提出采用二分法对矿井瞬变电磁法进行全区视电阻率的提取,该计算方式很好地解决了视电阻率晚期计算方式在早期段的畸变对数据处理造成的影响,应用实例表明全区视电阻率计算方法在资料处理和解释中要优于晚期计算方法,可将其推广至以后的实际应用中。
In order to accurately and effectively predict the mined-out area near the heading head,present a dichotomy method to extract the apparent resistivity of the whole area by the mine transient electromagnetic method, which solves the effect of the distortion of the late calculation method of apparent resistivity on the data processing in the early stage, the application example shows that the whole area apparent resistivity calculation method is superior to the late calculation method in data processing and interpretation, and can be extended to future practical applications.
