Government-approved permits are required for all new and ongoing mining operations, including exploration activities. This permitting process ensures that environmental standards are maintained from the beginning to the end of mining and metal production operations.

Using a mixed-methods approach involving in-depth interviews, water and soil analysis, land-cover classification and participatory mapping, we analyzed the mining-community agreements and the mining impacts on the farming lands. We arrived at two primary conclusions.

Each of the models is developed from first principles based on typical mining criteria for rock densities, swell factors, drill penetration rates, etc. Industry-standard estimating methods are used for equipment selection, personnel allocation, and cost estimation. These models are invaluable for early order- of-magnitude estimates.

Subsurface mining where a rotating shear on the mining machine shaves from blocks or panels of mineral in a back-and-forth motion, similar to that of a meat slicer, and dumps the broken coal onto a conveyor belt that extends across the longwall. As the mining machine advances, the roof behind it .
