Forecasting and assessment of water abundance of sandstone roof by multivariate information

In view of the mine roof problem in the process of occurrence and prevention and control of water disasters, as well as the existing method to predict the roof sandstone water problems, this paper studies the multi-factor comprehensive analysis on the influence of water content, we pay more attention to scientific and practical index selection.It can make the best use of the exploration hole data. And verification was conductd in Jining No. 2 well. It provides a new method for water prediction in coal mine roof aquifer.
