Longwall output plan considered in probability aspect

Author: R. Snopkowski

During the last decades, role of the longwall production output has been considerably modified. In the eighties, and earlier decades, the production output was very often fixed by state regulations, having poor economical and technical basis.

Nowadays, the longwall production planning procedures arc based on economical premises, including technical conditions.

In the present study we have assumed that the longwall production output may be considered as a random variable. In order to evaluate the risk of the targeted plan collapse, including assessment of its realisation chance, a probability factor has been defined.

This procedure may be used as auxiliary tool used in planning the production output of any coal mine.
