INFLUENCE OF A STATE OF INTERPANEL PILLARS ON SPONTANEOUS COMBUSTION OF COAL
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
The main objective of researches was assessment of a stress-strain state of regional parts of a rock massif and coal pillars at various seam thickness, panel width and a mining depth. Dependences of extent of zones of limit state on the main geological and mining parameters are established. The increased hazard of mining of thick flat seams with the increased width of longwall panel is shown. Recommendations about decrease in the endogenous fire hazard connected with disintegration of regional parts of seam and chain enter panel coal pillars are made.
