In the nether, this will not work, as you cannot place water, so it is a good idea to make a fire resistance potion, as that will negate all fire damage, and as there are many lava pockets hidden in the wall, as well as giant lava seas, it will help. Even a partial blob usually provides enough diamonds to replace the pickaxe when it does break, or repair it when it's about to.

Weapons: A sword (stone or better), a bow, and plenty of arrows (except if their bow has the Infinity enchantment, in that case bring only one arrow. If players are mining in an area with sand or gravel, like a desert biome, they can break the sand or gravel blocks and see if any others fall.A bucket of water serves as both a fire extinguisher, if the player fall in; and as a way to form obsidian surfaces over lava pools (pour water onto a solid block adjacent to a lava pool; do not stand between that spot and the lava).

If a cave spider is encountered, make sure to quickly place a torch before it becomes hostile, and if it already is hostile, place a water bucket so that they will be pushed back by the flowing water, making it easier to kill. Just place the water next to the lava source, and the water will convert the lava blocks on top of the pool to obsidian. Mineshafts can contain cave spider monster spawners which are rather difficult to reach and destroy.Also, if players come across a lava lake or pool they want to cross, they can flood it to turn the lava into obsidian. Regardless of how the player arranges things, they need to light the shafts properly to avoid monsters being spawned. Moving through a cave too quickly makes it easy to miss unlit passages around the player where monsters can come out, and increases the chance of falling into a hole.

This takes more tools (since the player is digging everything out themselves), but with proper lighting, they will hardly ever see monsters. If the monsters are too much trouble, the player can also go to options and change the difficulty to "peaceful" to prevent mobs from spawning. Find one of the many caves that opens to the surface, and start exploring that, generally working the way downwards. The easiest way to make an infinite water source is to make a 2×2 pit one level deep, then empty two water buckets into opposite corners. Also known as cave hunting, caving, or spelunking, cave mining is simply the practice of exploring caves and extracting the ores found on its walls, floors and ceilings.

If it is the first mining trip, use a wooden pickaxe to mine some cobblestone and make a stone pickaxe. Build a 2 block tall pillar so you can attack the cave spiders while they are climbing up the pole, keeping them at bay and keeping yourself from taking damage. The player can also look for lava pools, all air between Y=-63 and -55 are turned to lava during world generation. On the flip side, they often contain a large amount of hostile mobs, and both water and lava can be troublesome. Mineshaft structures are often found intersecting caves, but the player may well stumble into one of these while mining their own tunnels.
