提出采用双巷网络并行电法探测工作面内薄煤区范围,为煤矿工作面内地质异常区探测提供新的物探手段,特别是对传统的无线电波透视难以穿透的大面宽工作面,更是有益的补充.网络并行电法采集数据方式简单,实现了整条电法测线电位数据的同步采集,显著提高了电法采集数据的效率和信噪比,可进行多种电极装置的电阻率反演.在工作面双巷中分别布置电法测线,所有电极均布置在巷帮煤壁中部腰线位置,利用网络并行电法仪采集电法数据,将双巷测站采集电法数据进行拼接,联合进行二维电阻率层析成像,可以得到工作面双巷间电阻率变化情况.根据薄煤区与正常煤体间的电性差异情况,分析薄煤区可能的电阻率表现形式,...

The two-gateway network parallel electrical technology is first prevented to explore the thin-coal area within coal face, which is a new geophysical surveying means for the geological anomaly bodies especially within the large width of coal faces that are difficult to be detected by the conventional radio-wave penetration method. With more simple data-collecting modes, the network parallel electrical method realizes the synchronous potential measurement of whole electrode array; so the data-collecting efficiency is greatly improved and the signal-to-noise ratio is also well enhanced. The colle...
