为快速、准确地超前预报巷道掘进前方异常地质体及采取相应的水防治技术措施,在室内水槽试验的基础上,通过构建巷道前方低阻异常模型,对不同距离低阻体的响应特征进行模拟与分析,为现场探测应用提供依据。淮南某矿底抽巷道探测实践表明,沿巷道掘进前方60~75 m段视电阻率值较低,初步判断该段岩层裂隙发育,含少量水;且与该范围相对应的底板两侧也存在不同程度的含水区,而其他探测区域视电阻率值则相对较高,富水性差。该探测结果与后续的生产实际情况吻合。
In order to quickly and accurately predict the anomalous geologic bodies in front of roadway and take corresponding water prevention and control measures, the response characteristics of low-resistivity bodies at different distances are simulated by constructing the low-resistance anomaly model in front of the roadway based on the experiment of indoor water tank And analysis, provide the basis for field detection applications. The practice of detection of mine roadway at the bottom of a mine in Huainan shows that the apparent resistivity value of 60 ~ 75 m in front of roadway is relatively low, and the fractures of the rock layer are developed with a small amount of water in preliminary judgment. There are also two sides of the floor corresponding to this range Different degrees of water area, while the other detection area apparent resistivity is relatively high, poor water-rich. The result of this exploration is consistent with the actual production situation.
