This CAD software is not able to calculate the volume of individual seams and layers but can calculate the entire volume of a mining stage, which should be identical to the volume calculated with GEOVIA SURPAC.
The results of of the calculation of each mining stages volume based on the block model is verified by a second software: AutoCAD Civil 3D. The planning of transport routes and the locations of required infrastructure, such as location of crushers, is conducted accorrding to these centres of mass.Īn ongoing controlling of each step in the planning process is primarily accomplished by the utilisation of a second planning software. The layout of the coal seams happens depending on the used equipment, the selection of which is conducted in cooperation with the client and based on the required production amounts and mining directions.Īn optimisation of mining in open pits is accomplished by calculating centres of mass. The masses of coal and overburden are calculated accordingly. When the best scenario was selected, a per-segment planning of mining and dump with proceeding stages from exposure to final pit is conducted. The individual scenarios usually differ by different required annual productions or final depths of the pit. GEOVIA SURPAC allows the creation of multiple scenarios which can be evaluated based on mining and economic methods, which allows a custom made and optimal solution that can be presented to the client. The maximum final depth is another important factor. Several factors need to be taken into account when selecting the best scenario: The exposure location should be the place of coal in the least possible depth in order to be able to assure a good overburden / coal - ratio. Also theme maps can be created for every sector individually.īased on the individual sectors multiple exposure scenarios will be developed in cooperation with the client. This povides a dependable basis for several different planning scenarios, which will be modelled in the further course of the project. This first step of planning also includes a preliminary planning of transport routes.
In the context of the mine planning the next step is the development of the "final pit", which is the basis for a rough planning of the mining process and the required dumps. The mine planning itself starts with the gathering of all available and relevant parameters, such as the clients planned annual production or the required slopes. The 3-D block model is the basis of all further planning processes.
In the context of the creation of a geological model, the first step is to acquire and process a vast amount of geological data. GEOVIA SURPAC is a comprehensive CAD system that allows for the planning and management of opencast and underground mining projects in every phase of the process. It is, however, also possible to import and process data from other software solutions, such as DataMine Studio. FUMINCO uses GEOVIA SURPAC for planning tasks. Nowadays, the deployment of modern planning software is one of the basic requirements for adequate and customer oriented execution of mine planning.
