Abstract:
Over recent years Anglo Coal Underground CM mines have consistently been able to
increase production output by improving their production process efficiency.
However, in the very same time, the utilization of available production time has
declined.
This report will explore the architecture of the current Performance Management System
(PMS) for frontline production section in Greenside Colliery, with specials impetus
given to the measurement front line time utilization.
Guided by existing literature and case studies on Performance Measurement Systems
and equipment time losses one was then able to conduct work studies in the erratic
underground coal mining sections. This was done with the view of building a factual
basis for process flows and root cause identification.
Informed by the above the report will give recommendations, on the short comings
and suitability of the current PMS, a concise definition of what ìproduction
downtimeî and illuminate critical areas of lost production.
From the study of best practices the PMS was found to be suited generally for
frontline coal management. However more needs to be done in improving the
accuracy of the data recorded and its communication.
A definition was fabricated for Lost Production Time based on the existence of a
critical value chain. Based on this definition the critical areas of lost production time
were identified and summarized in diagrammatic form that will be used in the data
capturing of the new PMS.
The study found that Continuous Miner operational stoppages and Feeder Breaker
breakdowns present the best opportunities of improvement and recommends that work
studies be done to improve the operational stoppages and equipment redesign
consideration be made to reduce shearing pin and torque shaft damage.
The report culminates by giving further recommendations based on findings on other
aspects that are not contained within the project scope but however do have a bearing
on the efficiency of the total PMS.
