Production Start...
July 1, 2020 - The termination of the coal supply contract between Comisión Federal de Electricidad and Dos Republicas Coal Partnership (“DRCP”) eliminated DRCP’s need for coal from Eagle Pass Mine, and resulted in mine closure.

Dos Republicas’ 6,348-acre Eagle Pass Mine is now working toward full reclamation.

Summary:

Predominantly all machinery and equipment belongs by the owner of the mine.

The Eagle Pass Mine began selectively mining the thin coal seams with a Wirtgen type 4200 SM surface miner in October 2015.

The Wirtgen surface miner is used to selectively extract coal from the rock. This enables to achieve a high material quality. The four seams lie beneath an 18.3 m layer of top soil and overburden, in a series of layers around 6,0 m thick. Barely 1.65 to 2.0 m of this is coal.

The 4200 SM transfers a 250 t payload onto dumpers. They transport the coal to a transshipment center equipped with five grizzlies and conveyors. Each grizzly supplies one loading conveyor which transports the coal to the train-loading station.

The surface miner crushes the coal to a maximum size of 10 cm while minimizing fines. As coal fines tend to block the loading conveyors at the transfer points when there is a high moisture content, a low proportion of fines is a great advantage. Almost 95% of the coal is crushed and loaded by the 4200 SM. The remaining 5% – i. e., material located in inaccessible corners or right at the end of a drift – is broken up by bulldozers and loaded by front loaders.
