求翻译：矿井直流电法勘探是地球物理勘探的重要分支，它以岩石导电性差异为基础，通过测量和分析巷道或采场附近稳定电流场的分布变化规律来研究矿井地质问题。是什么意思？

Mine exploration of the direct current method is an important branch of the geophysical exploration to rock conductivity differences, based on the measurement and analysis of the roadway or near the stope stability current field distribution variation to study the mine geological problems.

DC law mine exploration geophysical exploration is the important branch to rock it, electrically conductive differences, with the measurement and analysis or a gallery near the current stable distribution pattern of changes in coal geology research.

The mine pit cocurrent electrical prospecting is the geophysical prospecting important branch, it take the rock conductive difference as the foundation, the stable electricity flow field distribution change rule studies the mine pit geology question through nearby the survey and the analysis tunnel

DC electrical method in mine exploration is an important branch of geophysical exploration, based on conductivity of rocks based on differences, through the measurement and analysis of roadways or near Stope stability study on changes to the current field of mine geological problems.
