There are 2 places. If you go to Oreburgh city (first time going), you will go to an underground mine. And in Eterna City ( the next city after Oreburgh), in 1 of the buildings there is someone called underground man. he will give you an explorers kit. which has a shovel to dig underground
You can get a blue, green, red, pale, and prism orb underground.
