| 摘 要： | 在煤矿井下工作面两侧巷道有限空间内采用矿井瞬变电磁多方向交叉观测系统,对工作面顶板或底板尽可能采集较多的数据。对采集的原始数据进行数据预处理、数据转换、数据提取、成切片图等相关处理后,通过综合分析不同水平切片图,从而确定对应探测范围内异常体的电性特征、中心位置、发育趋势等,为地质水文预测预报提供可靠依据,从而确保工作面安全回采。

| Abstract: | The mine transient electromagnetic multi-directional cross observational system was adopted in limited space of adits on the two sides of the work face,and as many data as possible were collected in roof or floor of the work face.Relevant processing procedures were performed for collected data,such as data preprocessing,data transfer,data extraction and level slicing.An integrated analysis was made for different horizontal slices,and hence the physical parameters of the anomaly in the detection limits such ... |
