COMPUTER CONTROLLED MEASUREMENT OF SPONTANEOUS COMBUSTION IN THE COAL STOCKPILES -OF WESTERN LIGNITE CORPORATION (WLC)

Öz

Abstract. Spontaneous combustion is inevitable in case the coal meets suitable

environmental conditions. Therefore, in the measurement system with computer, it

is aimed to take the temperature changes automatically occurring in the stockpiles.

In order to realise this scope, a total of 20 heat sensors were located inside the pile

which is excess of produced coal in WLC. The signals obtained from these sensors

are changed into electrical signals. After processing these signals with necessary

filtering, then temperature data are taken into the computing media by the

utilisation of analogue - digital transforming unit and recorded in a data log.

Hereafter, the graphs formed from these time - temperature data are presented to the usage of mine management.
