Finding Monster Spawners is a game of luck, if you play with sound when mining you'll occasionally can hear a Monster Spawner (that is one mob and just that mob). If you do hear them, you have a tiresome task ahead of trying to locate where the sounds comes from to locate the Monster Spawner.

However, it's better to explore Caves or Abandoned Mineshafts, and then find a sudden streak of a given mob leading the way to a Monster Spawner.
