Determination method of rational position for working face entries in coordinated mining of section coal pillars and lower sub-layer

Abstract For the study of the layout of the roadway in the coal pillar and floor strata co-mining working face at the Zhaogu No.2 mine, a mechanical model of the segmental coal pillar within the working face was established through theoretical calculations. The analysis considered the stress state o...
