Description

technical field [0001] The invention belongs to the technical field of goaf detection in open-pit iron ore stopes, and in particular relates to a high-density resistivity electrode suitable for open-pit iron ore stopes. Background technique [0002] In the process of mineral resource development and utilization, due to random mining and indiscriminate mining and the transformation of scattered mining into overall mining in the process of mining integration, there are many unknown goafs in and around many mines, and these unknown goafs There is no detailed geological data, and some goafs may have been filled with water and deformed, and these unknown goafs are seriously affecting the daily production of the mine, and are always threatening the safety of stope workers and equipment. Therefore, how to accurately detect gobs has become one of the security problems that open-pit iron ore stopes must face at this stage. [0003] At present, the high-density resistivity method is ...

AI Technical Summary

Problems solved by technology

[0006] However, during the electrode laying process, since there is no shelter in the open-pit iron mine stope, the electrodes will be exposed to sunlight for a long time. The water is easily volatilized, resulting in the inability to maintain a relatively humid environment between the electrode and the ground, resulting in poor electrical contact between the electrode and the ground, and ultimately affecting the accuracy of data collection

[0007] Furthermore, if the ground surface at the measurement point is a hard rock base, the electrodes of the traditional high-density resistivity method cannot be fully inserted into the ground surface, which will also affect the overall quality of the data
