摘要
In order to probe into harmful geological bodies such as faults, folds, seam-thinning areas, collapse columns for the safety of coal mine production, the author designed and developed a high-density resistivity instrument in accord with the requirements for coal mine explosion-proof. Two independent channels, i.e., current channel and voltage channel, were designed. Furthermore, the instrument also has a portable intelligent distributed electrode system, which can flexibly compose a two-dimensional measurement system. The instrument has been designed in accordance with the requirements for explosion-proof in the coal mine.
