Acoustic impedance inversion is a key technique for the seismic exploration of coalfield, which can determine subsurface lithological changes and coal seam distribution. The traditional method highly subjective, has poor generalizability, interpretation be time labor consuming. Due to powerful nonlinear feature extraction capabilities neural networks, deep learning technology demonstrated poten...

Water inrush disasters in mining areas are one of the most serious geological coal mining. The purpose this study is to establishment a water chemical database and source discrimination model Weibei coalfield provide basis for regional hydrogeological conditions future under pressure area, as well rapid identification sources coalfield. In paper, conventional hydrochemical trace element mine wa...

In the field of coalfield geological research, era traditional research has basically ended. At present, it is in period earth system scientific research. Starting from main factors affecting high-resolution seismic exploration and combining with some examples coal exploration,.this paper analyzes discusses middle methods exploration, mainly several key links data acquisition process, makes a b...
