Overburden Stripping. The operation of a quarry begins with stripping the overburden (the soil and subsoil above the bedrock). The overburden is stripped with an excavator, dragline, ripper, bulldozer, grader or other earthmoving equipment, and placed in large dump trucks. This process is repeated as the faces advance.

2. I usually quarry over the ocean. No blights on the landscape, instant obsidian, and being (mostly) static water, very little lag. As for the oil, the pockets are fairly well contained in the water and can stay there. 3. Using a bucket of monster essence will displace both oil and water if you get a decent cover.

2. Underground mining. Underground mining is used to extract ore from below the surface of the earth safely, economically and with as little waste as possible. The entry from the surface to an underground mine may be through a horizontal or vertical tunnel, known as an adit, shaft or decline. Underground mining is practical when:

Solution mining is used to recover deep deposits that would be uneconomical using underground methods, but only if the ore can be easily dissolved by a solvent. In this method, holes are drilled from the surface into the deposit. A solvent is pumped down one hole, and the resulting solution with the dissolved mineral is pumped out another hole.
