Room and Pillar Mining - an overview | ScienceDirect Topics

Pramod Thakur Ph.D., in Advanced Mine Ventilation, 2019. 21.3.4.1 Self-Inertization. In room and pillar mining, pillar extraction can be so designed that mined out area is submerged in water.This provides excellent inertization but is possible only in highly inclined coal seams. Most commonly, self-inertization is provided by the methane gas released from coal seams in the gas emission space.
