Method Of Mining Montmorillonite In Nigeria

Journal of Geophysics and Engineering, Volume 14,

The key solution to the safe mining of coal over a deep confined aquifer is to obtain and understand the deformation and failure characteristics of the working face's floor strata. In this work, we took a typical fully mechanized mining deep double-longwall working face floor of Chengjiao Coal Mine as a study case.
