Introduction of standardization of powered roof supports to increase production efficiency of Polska Grupa Górnicza S.A.
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2018, Vol 536, Issue 4
Abstract
The introduction of the standardization of a powered roof support is a key point in increasing production efficiency in the mines of Polska Grupa Górnicza S.A. The introduced changes will increase the safety of the miners and affect the economic result associated with the exploitation of coal. The purpose of introducing this standardization is to systematize the construction solutions of roof supports in terms of power and control hydraulics, focusing on all technical conditions that powered roof supports operating in underground mining facilities must meet (including mining tremors). This article presents the method of standardizing the powered roof supports that are produced, modernized, and renovated by Zakład Remontowo-Produkcyjny within Polska Grupa Górnicza S.A.
