Paper Title:
Short Wall Box Style Mining Method of Strip Coal Pillar under Town
  Abstract

To recover strip coal pillar and reduce cost after strip mining, the short wall box style mining method was presented. Strata stability was analyzed based on support plate theory, mechanical model of the second strata movement was created, and safety factor was deduced .The ground movement and deformation were predicted, with probability integration method. The application demonstrates that this mining method can protect buildings on earth’s surface, improve the recovery ratio of coal and reduce cost. This mining method has a good economic advantage and environmental benefit.
