Jason Kenney's embrace of open-pit coal mining has

2021-2-3  The old policy prohibited mountaintop removal coal mining in sensitive areas on AB's Eastern slopes. Rescinding the policy opens Category 2 areas to mountaintop removal coal mines. "Stronger rules" = less protection, more mines, fewer mountaintops, and more pollution. Nice snow job, Jason. Expect an avalanche of opposition.

Energy analysis of open-pit coal mining Semantic

Conclusions1. The use of energy criteria to establish the mine boundaries corresponds to the role of coal-mining enterprises as subsystems within the energy-production system. The criteria here proposed reflect the level of technology not only within coal mining but also within the power industry and in transportation. It is important that the parameters included in the criteria have a ...
