open pit mining of coal
Panian Mine, Semirara Island, Philippines
Most of the coal is used for energy generation in the Philippines, with some exported to India and China. The Panian coalfield is being mined using openpit methods. The rock and soil above the coal layers (or seams) is known as overburden. Overburden is removed from the pit and heaped into piles, several of which ring the northern half of the pit.

Coal | National Geographic Society
A pit, sometimes called a borrow, is dug in an area. This pit becomes the openpit mine, sometimes called a quarry. Openpit mines can expand to huge dimensions, until the coal deposit has been mined or the cost of transporting the overburden is greater than the investment in the mine. Openpit mining is usually restricted to flat landscapes.

Coal Mine Degradation
Openpit coal mining is proposed in the valley that is the source of the OldMan River. This has the potential to DEGRADE the water quality for over 200,000 Alberta residents who get their water from the Oldman and South Saskatchewan Rivers. This includes Selenium and other pollutants.
Environmental Consequences of Open Pit Mining

Environmental Risks of Mining
Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
