Geological terrain mapping is an effective method for development planning and management of geohazards in an area where basic information was collected in the field that involving geology, topography and landform as well as geodynamic features.
Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals form the core of geophysical signal processing. While there are many methods in the geophysical survey, where we will mainly use magnetic and resistivity.
Pitting and trenching are methods to see a complete picture of rocks. In this process, the surface soil will be removed using heavy equipment and the bedrock will be exposed. Trenches will be excavated to expose mineralized zones for sampling and testing.
The design of a drill plan depends on whether it is designed to discover a new deposit or to delineate an existing resource. Some projects require drilling at a close spacing to provide a high level of certainty in the results before mine planning starts.
The purpose of drilling is to confirm if anomalies in data are accurate and provide evidence of a concealed ore deposit. Anomalies are often ranked according to the specific strategy and geological rating, those ranked highest are normally drilled first.
3D Modelling enables geologist to evaluate exploration risk, mine stability, grade distribution as well as to provide a basis for robust resource estimation and conceptual mining studies. Exploration and mining projects are often depending on the comprehensive understanding of deposit’s 3D geometry.
Mineral Resource Estimation is a method to determine and define the ore tonnage and grade of a geological deposit. A typical resource estimation normally involves the construction of a geological and resource model with data from various sources.
Pit design is crucial before drafting any mine scheduling. Data of the mine will be collected and pit design will be created accordingly.
Mine planning and the schedule is the foundation of all mining activity, it most accurately reflects the real-time reality of the geological structure in the ground. Planners and schedules are under constant pressure to create mine plans that are as accurate as possible to optimize production at all stages in order to optimize mine profitability.
In mine planning, metallurgy is a domain of materials science and engineering that studies the physical and chemical behaviour of metallic elements, inter-metallic compounds as well as mixtures of the metals.
Ore Reserve Estimation in mine planning is often carried out for various purposes. Most operating companies make periodical ore-reserve estimation usually at least annually, to determine their ore-reserve position for controlling development and exploration and allocation of funds or as a basis for deciding upon operating policy.
