Problems of dust control in coal mines

The problems of dust control in sanitary and technological assessment of air in coal mines and in explosion hazard management in underground excavations are discussed. The impact of coal dust on industrial safety and health of miners is described. The mathematical expressions are given for determining dust volumes entering lungs of human beings depending on dust concentration in air. The expressions to find errors in dust calculation in lungs are obtained. The error of dust mass in filter cake after a shift is compared with the error of dust mass in multiple sampling. The approach to determining technically reachable levels of current average dust concentration in mine air per shift and the methods to improve operativeness of dust concentration estimate in coal mines are proposed. The methods of the objective determination of dust deposition mass and distribution in an underground excavation are discussed. Their advantages and disadvantages are analyzed. The current methods of determining dust condition and dust deposition level in mine workings are assessed. The relevance and difficulty of the problem of continuous explosion-hazard dust deposition control in coal mines is emphasized.
