Empirical models, developed on the basis of the results of tests on dust deposition and changes in concentration of dust in the protective zone, are the proposed tools to reduce risk of coal dust explosion. The paper presents possible applications of such models to assess and monitor volume of dust in a protective zone. Underground tests were conducted in the tailgate and headgate of longwall 121 of Brzeszcze Coal Mine. Basing on the analysis, the empirical models describing relationship between changes in dust concentration, and dust deposition in a protective zone of roadways: headgate and tailgate of longwall 121 in Brzeszcze Coal Mine, were developed. The developed models show a possibility of predicting explosive dust deposition in a protective zone. After additional research is run, it is planned to generalise the developed empirical model, which will enable monitoring of protective zones.
