Figure 3 demonstrates the economic block model of the hypothetical copper deposit prepared to be imported into the OPPS problem The mining operation was considered to continue Block models describe the three dimensional volumes with relatively small sized parallelepipeds Block models are convenient tools for mine evaluation resource estimation and mine planning including pit or stope optimization and mine scheduling The vast majority of mineral resource estimates are obtained using block
Blocks should be mined and which ones should be left in the ground In a effort to identify the blocks to be mined an economic block model is created first from the geologic grade model This is done by assuming production and process costs and commodity prices at current economic conditions i e current costs and prices Then using the To support open pit studies related to seafloor massive sulfides mining projects an economic block model is required A modular framework is proposed to produce economic block models accommodating various levels of data The framework is illustrated on a site of interest located on the Arctic Mid Ocean Ridge

The process of calculating BEVs converts a geological block model into an economic block model For each set of input parameters applied the BEVs distinguish economic and uneconomic blocks 5 A block will be economic to mine if its BEV is positive and uneconomic if negative The final pit limits define what is economically mineable from a given deposit It identifies which blocks should be mined and which ones should be left in the ground In an effort to identify the blocks to be mined an economic block model is created first from the geologic grade model
ABSTRACT Most algorithms developed for optimisation of the mine layout and production scheduling for both open pit and underground mines are implemented on an economic block model of the ore body There are various formulae for calculating the economic value of a block The grade density rock type and confidence are all unique to each block within the entire block model An example of a block model is shown on the right Once the block model has been developed and analyzed it is used to determine the ore resources and reserves with project economics considerations of the mineralized orebody
