Mining

Mining is one main thing of minecraft. It allows you to get cobblestone, iron ore, gold ore, obsidian, diamond ore and moss stone. (Only near mob spawner) Use these items for tools and gears like iron chestplate or furnaces. Depending on the strength of the pickaxe, you will be able to mine a certain ammount of level. For example, the grid at the bottom will help you. When mining, a certain ammount of time is needed. The higher pickaxe type above the minimum level, the faster it is. The only exception to mining is bedrock which is unbreakable. Even using single player commands, instantmine isn't going to stop bedrock on his tracks. The only working strategy would be creative mode. More info on bedrock is obviously, the bedrock page.
