Anotace: 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.
