The Planning Optimization System for Underground Hard Coal Mines

Abstract

This paper presents a planning optimization system (POS) for underground hard coal mines. This POS is a computer program called the “CPRG.SYS”, which is based on CPRG method (Metoda Centralnego Planowania Robot Gorniczych). CPRG method is developed for modeling and the optimization of mining works in a multi-mine enterprise. The main elements of the presented system are: a database of recent and planned longwall faces, a knowledge base allowing automatic composition of longwall complexes, and a selection of equipment with reference to working conditions. An integral part of the system includes calculation modules allowing the analysis of multiple variants, using network techniques and suitably prepared evolutionary algorithms as well.
