How should a novice in My World mine?

How should a novice in My World mine? In this game of my world, mining is an eternal topic. Today, I will tell a new friend about mining.

Mineral distribution:

0-5: bedrock

0-30: Magma

0- 14: diamonds

0-30 years old: metal and lapis lazuli

0-60: Iron

0-70: Coal

Three basic mining methods:

1. Choose a cave among many open-air caves and start exploring, so that your exploration road can go as far as possible. Even shallow caves can provide abundant coal and iron ore, and there will be other mineral deposits such as gold mines in deeper layers.

2. If you don't find an accessible cave entrance, but find a shaft or canyon, mining there is also a good choice.

Of course, you can also make your own entrance to the underground world: dig a shaft at a convenient location (such as the basement of a room), and then start horizontal excavation at a suitable height.

Mine defense mode:

Tunnel collapse system is one of the ways to protect your mine. This is actually the miner pressing a button, retracting the sticky piston on the wall and unplugging the flashlight on the wall. These torches support the sand or gravel above them to prevent them from falling. When the viscous piston retracts, the torch no longer adheres to the wall and then disappears. This caused sand or gravel to fall and blocked the tunnel. This can be used to prevent tunnels in the mine network from being attacked, while still allowing access to the blockade area. It can also be used to catch attacking creatures in the "isolation zone" and prevent them from wandering around the mine.
