    Mountaintop Removal Mining: Before And After –

    2016. At over 3,000 acres, this mine complex includes at least 15 valley fills. Valley fills are created when mountain ridges are blown up to access coal, and the excess rock and debris, known as overburden, is dumped into the valleys below the mountain. This activity buries headwater streams, damaging water quality for miles downstream.

    Weighing the cup before and after allows the mass of the coal that has left the cup to be determined and, thus, the net charge to mass ratio can be calculated. For copper beads the charge to mass ratio was -3 pC g for freshly ground coal and -0.5 pC g one month after grinding. For copper coated iron, two month old coal gave a q m of +0.08 pC g.
