An open pit mine is - literally - a PIT: it is mined VERTICALLY instead of horizontally, and the removed non-ore material is stockpiled until ALL (or almost all) of the mining is done, and THEN it is returned. Reclamation occurs mainly at the end of the mining process.

In underground mining, mine shafts are bored or dug from the surface to the underground layers where the ore is located, and ore extraction takesMINE DEVELOPMENT – ACCESS TO DEPOSIT,underground mine. Some of these factors include the depth of the deposit, geotechnical aspects, production rate, dimensions, availability of capital, and operating costs. A key consideration is that it is extremely expensive to convert from a ramp to a shaft system, so the mine engineer/planner must consider the entire mineral resource or potential to increase the resource at depth.
