Title:
METHOD FOR PREDICTING WATER-RICH LEVELS OF SANDSTONE IN COAL SEAM ROOF
Document Type and Number:
WIPO Patent Application WO/2019/091134
Kind Code:
A1
Abstract:
A method for predicting water-rich levels of sandstone in a coal seam roof comprises the following steps: A. performing on-site sampling of sandstone at N sampling locations in an underground coal seam roof, and analyzing, at each of the sampling locations, the sandstone in the coal seam roof to obtain three water-rich levels thereof and six influencing factors influencing the water-rich levels, so as to establish a sample database; B. after pre-processing data of the sample database, establishing a Bayes classifier based model for predicting water-rich levels of sandstone in a coal seam roof; C. training and testing the Bayes classifier based model for predicting water-rich levels of sandstone in a coal seam roof; and D. performing on-site sampling at a sampling location of the sandstone in the underground coal seam roof, and using a Bayes formula to predict water-rich levels of the sandstone at the sampling location in the coal seam roof on the basis of the Bayes classifier based model.
