Abstract:
The paper presents some information about gas and coal outbursts threat in Polish coal mines. It shows the methodology for threat identification and monitoring for gas and coal outbursts in the Polish coal mines. One of the main methods of assessing threats in the mining industry in Poland and China is desorbometric method. The paper presents some results of estimation of uncertainties of the desorption rate Δp, determined in situ, by use of liquid manometric desorbometer gauge. It was observed that, if there are coal subgrains in desorbometer contaminator, the results of desorption rate may be even up to 60% higher than results obtained for the normative sample. Possibly method of the uncertainty reduction are presented in the paper as well.
