摘要：

An impact assessment of the run-of-mine dilution on hard coal production efficiency is presented in the article. The data were taken from three longwall faces, conducted in a thin seam. Empirical data were subject to a statistical analysis aiming at the development of a mathematical model of an advance of longwalls depending on a quality structure and an amount of the run-of-mine from the ploughequipped longwall faces. The Monte Carlo method, an analysis of agglomerations and an analysis of scenarios enabled to develop a mathematical model. Afterwards, an analysis of the economic efficiency of the mining process, bearing in mind scenarios assuming an improvement of the run-of-mine quality, was conducted.
