About this document
Methods of Depillaring in Mining by Parvez Bodh is a document available to read on EtoBox.
This document discusses various methods of depillaring, which is the extraction of coal pillars underground while leaving some void space and allowing controlled roof collapse. It describes two main methods: 1) Depillaring by caving, which involves splitting large pillars into smaller pillars ("stooks") and extracting them sequentially while allowing the roof to cave in, and 2) Depillaring of contiguous seams, where two adjacent coal seams are extracted simultaneously using coordinated methods that account
