Coal Reserves are part of the coal resources of known dimensions, the distribution of quantity, and quality, which at the time stated the feasibility study feasible to be mined by considering the conditions that took place at this time.
The conditions include among others:
1. Technology, associated with the mining area, level of difficulty in making coal and topography where the coal was found. Technology concerning the types of equipment used, the number and capacity of each of these devices, which can be calculated that the cost estimates will be issued by the company.
2. Environmental conditions, associated with the location of settlements, agriculture, forests, roads and other facilities that are no longer allowed to be land mines, so the calculation of reserves should be outside of this location, and should be considered also for the determination of disposal, mines roads, road transport and location of coal accumulation and also the determination of coal quality specifications are sold.
3. Government Regulations, which relate to mining permits environmental laws and regulations and other land reclamation binding to the mining company that eventually will affect the stripping ratio.
