ABSTRACT

Self-ignition processes are a serious problem in brown coal mining and depositing.
Infusions and following fires are frequent events in open pit brown coal mines with seams influenced with previous underground mining, homogenisation and other deposits, and on stock-piles of power and heat stations and industrial plants combusting
coals as well. The objectives of the project from the ALFA programme No. TA01020351 are presented in this article. The project solves a research, development,
and verification of a complex overall methodology of an early identification of an
initiating irreversible infusion state of brown coal mass aiming to an ignition (fire) of
brown coal mass. A thermovision scan and continuous evaluation of the surface
temperature of a deposit or a seam is a basic method used. An early localisation of
originating fire seat in a “prenatal” state will enable an in time prevention fire action
and will stop or largely decrease the negative phenomena mentioned above.
