Method of predicting air pollution of coal mines with use of new synthetic materials

Abstract

Presents a methodological approach that enables on the basis of laboratory experiment to give a hygienic evaluation of synthetic materials used in coal mines to harden coal and rock masses to prevent rock falls and caving and for hermetization of ventilation equipment. Polyurethane, carbamidoformaldehyde and phenolformaldehyde plastic foam are studied in an experiment tha examined quantitative emission ofsubstances from their original components in the process of forming contaminants. Synthetics in a beaker are placed in an exsiccator, mixed with air, samples of volatiles particles collected and dynamics of their emission are calculated using regression and linear equations. Amounts of 2,4- toluenediisocyanate and diethylamine produced by polyurethane, and formaldehyde and methanol from carbamidoformaldehyde did not exceed limits of maximum concentrations; phenolformaldehyde plastic foam produced amounts of phenols and formaldehydes that are significantly higher than maximal permissible concentrations. Laboratory procedure and use of formulae were confirmed by testing air in a Donetsugol' mine. Polyurethane and carbamidoformaldehyde didnot contaminate air above hygienically safe limits, while phenolformaldehyde plastic foam exceeded safety limits proving need for hygienic measures to protect miners from its contaminants. Adequacy of laboratory-mathematical method to evaluate emissions of harmful chemicals from resins under mining conditions shows value of laboratory testing of  More>>
