Three Dimensional Graphics Modelling as Applied to Longhole Stoping Design

A 3D graphics modelling system has been applied to longhole stope ring design at Z.C. Mines, Broken Hill, NSW. This has been in operation for a four month period (January, 1988). The purpose of this application was to provide computer assistance to mine planning engineers and blasthole design draftsmen for the longhole design process, particularly by: 1. reducing the- volume of tracing, drafting and geometric manipulation which is a significant feature of the manual design process, 2. providing additional design drawings to enhance the conception and implementation of stoping design.
