Steps in Opencast mining 1) Determination of mine boundaries: Exclusion of: high SR area (deep seated, hill, thinning/splitting of seam, stone parting, geologically disturbed areas (faults), low quality areas, etc. natural boundaries (river/nallah, faults), township, railway line, operational factors like optimum strike length for transportation.
There are four main mining methods: underground, open surface (pit), placer, and insitu mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
The available mining fleet for underground mining consists of five underground loaders and eight haul trucks, each with a 60tonne payload. The daily production rate is approximately 95,000. tonnes. The .
