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 a coal deposit, for example, the following values are of importance for mine and power plant planning: The work focus lies here on the mining material. The implementation happens by using user defined block attributes, of which 256 can be saved per block. The last step in the development of a geological block model is the implementation of the geological, hydrological, chemical and physical data from the drill hole database into the corresponding blocks by applicating of geostatistical methods such as "inverse distance" or "nearest neighbour". The big advantage of a block model is that the deposit body is fragmented into geometrical entities, which allows for cutting or delimiting of the deposit body for different planning stages and thus for exact calculations of volumes.
In order to be able to display a detailed map of the deposit, a so called block model is created based on the drill hole database and the 3-D profile data. The next step in modelling a deposit is the creation of 3-D geological profiles.
SURPAC GEOLOGY DATBASDE SOFTWARE
The software intern drill hole database can process information about the course of the drilling and about the geology of the drilled hole.
This information is imported into GEOVIA SURPAC via database functions. Detailed information about the deposit are usually gathered by drilling exploratory boreholes. Additionally, a check for plausibility is conducted. 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.
