Mining Bedrock in Minecraft with Fabric-Bedrock-Miner

Ever wanted to excavate below bedrock or carve massive caverns where normal picks bounce off harmlessly? Fabric-Bedrock-Miner solves exactly that problem by letting you mine bedrock blocks in survival mode using a Fabric mod, complete with configurable controls and support for Minecraft versions from 1.16.5 through 1.20.1.

What This Project Does

Fabric-Bedrock-Miner is a client-side Fabric mod that removes bedrock's indestructibility. That means you can actually excavate it with a pickaxe instead of watching it shrug off damage. But here's the catch (and it's intentional design): the mod doesn't just hand you free bedrock removal. Instead, it works within Minecraft's existing game systems. You still need a high-quality pickaxe with Efficiency V, a Haste II beacon for speed, and a setup involving pistons, redstone torches, and slime blocks to actually pull it off.

Think of it as removing a technical barrier, not removing the challenge.

Why You'd Mine Bedrock

This seems niche until you start thinking about what bedrock removal enables. On hardcore servers, some players use bedrock-mining techniques to create secret bases below the world floor. Building terraformers or custom terrain generators? You might need to go below the standard limit. Got a massive excavation project you're tired of doing around bedrock? Now you've options.

It's also just satisfying to do something Vanilla Minecraft says you shouldn't. The challenge of assembling the materials and the setup, then actually executing the mining operation - there's a reason the project has 673 stars on GitHub.

How to Install It

Fabric-Bedrock-Miner requires a Fabric environment, which means you'll need the Fabric loader installed first. Here's the dependency chain:

• Fabric Loader (base mod loader)
• Fabric API
• Fabric Language Kotlin
• malilib
• Fabric-Bedrock-Miner itself
• Optional: Mod Menu (for easier config access)

Most players install these through a launcher like MultiMC, Prism Launcher, or the official Minecraft Launcher with Fabric support. Download the correct JAR for your Minecraft version (the latest release, v2.0.3, covers 1.16.5 through 1.20.1), then drop it into your mods folder alongside the dependencies.

The README emphasizes building from source rather than providing pre-built installers, so you're downloading directly from GitHub releases. Make sure you grab the version that matches your Minecraft install - downloading the 1.20.1 build won't work on 1.19.4, for example.

One heads-up: this mod hasn't received updates for Minecraft 1.21 or the current 1.26.2 release. If you're running the latest snapshot or recent versions, you may need to stick with an older game version to use this mod.

Using Fabric-Bedrock-Miner in Practice

Once installed, the mod adds two keyboard shortcuts (both customizable):

• LEFT_ALT+B+C opens the config menu
• LEFT_ALT+B+M toggles the mod on and off

With the mod enabled, left-clicking bedrock blocks will start mining them just like any other block. But - and this matters - you need your pickaxe and Haste II beacon ready first. The mod doesn't bypass the material requirements; it just makes bedrock mineable instead of impossible.

Your setup should include an Efficiency V diamond or netherite pickaxe (lower tiers will take forever), a beacon beacon with Haste II active, and building blocks like pistons, redstone torches, and slime blocks. The reason for all these? Bedrock mining often involves moving the blocks afterward or creating specific structures, so you need redstone machinery nearby.

The videos linked in the project showcase actual mining operations, which is honestly worth watching if you're serious about trying this. Seeing it in action beats reading about it.

Critical Warnings for Servers and Anti-Cheat

Here's what you absolutely need to know: most multiplayer servers, especially competitive ones, run anti-cheat systems that'll detect and ban modified clients. Fabric mods are third-party client modifications. Using this mod on a survival multiplayer server without explicit permission from the server owner is a quick way to get kicked or banned.

Before installing any client-side mod, check the server's rules. Some servers explicitly allow Fabric, some allow specific mods, and many ban any client modification outright. Single-player worlds and private whitelisted servers where the owner approves it? Go wild. Public servers? Honestly, assume it's not allowed unless stated otherwise.

Also note that this is a client-side mod. It doesn't require server-side installation, but that doesn't make it server-safe. The server sees you mining bedrock and flags it as suspicious behavior.

Common Gotchas

The most common mistake? Trying to use this without sufficient preparation. Bedrock mining is slow even with Haste II and Efficiency V. You'll need patience and a lot of pickaxe durability. Bring multiple pickaxes or repair them at an anvil. On a similar note, actually moving mined bedrock blocks requires the redstone machinery setup - bedrock can't be picked up by regular hoppers, so you need pistons and slime blocks to relocate it.

Another gotcha is forgetting which keyboard shortcut does what. The default binds are easy to mix up, especially the config menu shortcut. I'd recommend changing them to something more intuitive if you plan to mine bedrock frequently. Hit the config menu with ALT+B+C and rebind as needed.

Version mismatch is another common problem. The mod versions are extremely specific to their Minecraft version. Using the 1.19.2 build on a 1.19.4 installation will just silently not load, or the game may crash. Always match the version number exactly.

Other Approaches to Consider

If Fabric-Bedrock-Miner doesn't appeal to you, there are alternatives. World editing tools like WorldEdit (on Creative Mode servers or single-player with mods) let you excavate anything instantly, though that's more "cheating" than "mining bedrock." Some players use vanilla Redstone machines and piston logic to push bedrock around without actually mining it - technically not bedrock removal, but it achieves the result of relocating blocks.

There's also just accepting bedrock as a boundary and building creative structures around it. I know a player who built an upside-down castle floating below the bedrock layer by using command blocks and structure blocks in Creative. Not the same as mining it, but equally impressive if you're into engineering.
