Numerical Simulation of Rational Width of Coal Pillar for Roadway Driven along Gob

Shijian Zhou

Abstract

This paper applied numerical simulation software-FLAC3D to calculating stress field and displacement field of surrounding rock of roadway driven along gob for rational pillar width.It presented 5m pillar was rational for roadway safety by analysis of observation data in mining and roadway driving,which was reference to narrow pillar design for roadway driven along gob.
