Underground Coal

The aim of this course is to provide participants with a comprehensive understanding of the factors that influence the design of a longwall mine. As a result of attending this course, participants will have a greater understanding of how the major design decisions for a longwall mine are made, be able to optimise the mine layout and make better decisions in the analysis of a 
mine design.

Course Content

Introduction

Health & safety, world coal mining, open pit verse underground, and resource base.

Asset Evaluation

Allocation of assets, evaluation process, and margin ranking.

Geology & Exploration

Coal types, properties, exploration, modelling, design considerations, and reporting.

Mining Systems

Selection drivers, technical considerations, equipment required for each system.

Geotechnical Assessment

Assessment parameters, support design, and influence on design/operation/ profitability.

Ventilation & Gas Management

Gas reservoirs, economics, uncertainty in testing, drainage systems, and equipment & structures.

Mine Design Parameters

Access, panel orientation, resource coverage, width, flexibility, risk assessments, and selection.

Equipment Selection

Equipment & services required, maintenance process, non-productive time, capital estimation.

Coal Clearance
