Abstract

Abstract: Abstract:In order to better solve the coalmine advanced water forecast problems,Based on the problems of coal roadway leading water technology research,the paper presents a new coal roadway drilling induced polarization advance water forecasting techniques and methods, which overcomes the effects of interference factors in roadway,and remote detection in heading face evolved into a borehole close observation detection by borehole observation detection.At the same time, systematical analysis of the theory and the analysis methods of the technology.After a space simulation test and test, detection and analysis on coal mine, summing up a set of coal roadway drilling induced polarization analysis technology of advanced water forecasting.
