Surrounding Rock Deformation Properties and Control Technique for Roadway along Goaf in Soft Rock

Article Preview

Abstract:

Deformation of roadway driving along goaf was very serious during mining in Qidong coal Mine.This paper took the roadway as the engineering background, firstly, numerical simulation of the roadway has been made by FLAC3D,then its surrounding rock deformation properties and stress distribution were analyzed,the reinforcement technology was proposed during mining, lastly, the deformation around roadway during mining was observed and analyzed. The practical engineering shows that : the combined supporting of bolting-shotcreting-grouting can effectively control the deformation around roadway, the supporting effect is good , and better social and economical benefit have been gotten.
