  • Basics of an open pit mine

    Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal. In a hard rock mine, the bottom of the pit would be the

    The groundwater from the mines is more acidic than surface waters and disrupts ecosystems by changing the pH conditions of soil and water sources. Subsurface mining operations don't create the visible changes in the landscape that surface mining operations do, but the conditions of subsurface mines are extremely hazardous for the working miners.

    How does auto mining work? Hi, I'm a bit confused about this feature. I placed a long time ago a miner on a copper node on Akkrum, and much later I placed some more on the moon on various nodes. Once I went back to the moon and collected the mined ores, but didn't check if the miners keep working. Now I checked the moon miners again, and they mined nothing, the mining nodes also disappeared
