Vein Mining Mod (1.21) – Mine 1 Ore Block and Get All Adjacent Ores

Vein Mining is a utility mod that adds a configurable Vein Mining enchantment, allowing enchanted tools to break entire clusters of matching connected blocks at once, available for Fabric, Forge, NeoForge, and Quilt mod loaders.

Mining in vanilla Minecraft is repetitive. You find a vein of iron, coal, or diamonds, and then you click each block individually until the entire deposit is gone. It is one of the most common complaints among survival players, and it only gets worse in modpacks where ores spawn in massive clusters. Vein Mining solves this by letting you break an entire connected group of identical blocks with a single swing — but unlike some overpowered alternatives, it does so through an enchantment system with highly tunable limits. With over 6 million downloads on Modrinth alone, it has become one of the most trusted quality-of-life mods in the Minecraft modding community. Developed by TheIllusiveC4, the mod strikes a careful balance between convenience and gameplay integrity.

Key Features of Vein Mining

• Enchantment-Based System — Unlike mods that simply toggle vein mining on or off, this mod ties the ability to a proper enchantment. You can find it on enchanting tables, in villager trades, and on loot books. This means players must earn the ability through normal gameplay progression rather than receiving it for free, which keeps survival worlds feeling balanced.
• Configurable Max Blocks and Distance — Server owners and modpack developers can set exactly how many blocks can be mined per activation and how far the chain reaction travels. Both values scale with enchantment level, so a Vein Mining I enchantment might break 10 blocks while Vein Mining III could handle 50. This granular control prevents the mod from trivializing resource gathering in competitive or progression-focused environments.
• Diagonal Mining Support — When enabled, the mod detects connected blocks diagonally, not just on the six cardinal faces. This is particularly useful for ores like diamond and ancient debris that often generate in scattered diagonal patterns. Players can toggle this setting off if they prefer a more conservative chain-breaking behavior.
• Relocate Drops — All items mined through a vein break can be automatically collected at the player's position instead of scattering across the mined area. This eliminates the frustrating experience of watching half your diamonds fall into lava or disappear into unreachable crevices deep underground.
• Tool Durability Protection — The mod includes a "Prevent Tool Breaking" option that stops vein mining before your tool reaches zero durability. Combined with the configurable tool damage multiplier, this ensures players never accidentally destroy a valuable enchanted pickaxe by triggering a large vein break. You can also limit mining strictly by remaining tool durability for the most cautious balance approach.
• Flexible Activation Methods — Players can configure vein mining to activate while sneaking, while standing normally, or through a dedicated keybinding. This flexibility means the mod adapts to your play style rather than forcing a specific input pattern, and it avoids conflicts with other mods that may already use the sneak key for different functions.
• Block Whitelist and Blacklist System — Administrators can define exactly which blocks are eligible for vein mining using whitelists, blacklists, and custom block groups built from tags and block IDs. This is critical for modpacks where certain modded blocks should not be mass-mined for balance reasons.

How to Install Vein Mining

1. Choose and install your preferred mod loader: Fabric, Minecraft Forge, NeoForge, or Quilt. The mod supports all four, so pick whichever your existing modpack uses.
2. Download the correct version of Vein Mining for your Minecraft version and mod loader from the official Modrinth or CurseForge page. Double-check that both the game version and loader type match your installation.
3. Place the downloaded .jar file into your .minecraft/mods folder. If the folder does not exist, launch the game once with your mod loader to generate it automatically.
4. Launch Minecraft and load into a world. The Vein Mining enchantment will now appear on enchanting tables and can be applied to pickaxes, axes, shovels, and hoes.
5. To customize behavior, navigate to your .minecraft/config folder and edit veinmining-common.toml for gameplay settings or veinmining-server.toml for server-specific limits. The client config handles visual and activation preferences.

Pros and Cons

Alternatives to Vein Mining

• Ore Excavation — A long-standing vein mining mod that uses a keybind-based approach instead of an enchantment, offering a more immediate but less balanced alternative for players who prefer instant access to chain-breaking.
• FTB Ultimine — Part of the FTB suite, this mod provides shape-based mining patterns including tunnels and areas in addition to vein mining, making it a solid choice for players already running FTB modpacks.
• TreeChop — Focused specifically on tree felling rather than ore mining, TreeChop makes chopping trees break the entire trunk at once and is an excellent companion mod to pair alongside Vein Mining for complete quality-of-life coverage.

Frequently Asked Questions

Does Vein Mining work on multiplayer servers?

Yes — Vein Mining works fully on multiplayer servers. The mod primarily operates server-side, meaning the server administrator needs to install it, and all configuration options like max blocks, distance limits, and block whitelists are controlled through the server config files. Players connecting to the server do not necessarily need the mod installed on their client.

Can I use Vein Mining with Fabric and Forge at the same time?

No — you must choose one mod loader per Minecraft installation. Vein Mining provides separate downloads for Fabric, Forge, NeoForge, and Quilt, so download the version that matches the loader you already have installed. If you are unsure which loader to pick, Fabric and NeoForge are the most actively supported options for Minecraft 1.21.

Is the Vein Mining enchantment compatible with other enchantments like Efficiency or Fortune?

Yes — the Vein Mining enchantment stacks alongside standard tool enchantments. Fortune will apply its multiplier to each block broken in the chain, and Efficiency affects the initial break speed. This makes a fully enchanted pickaxe with both Fortune III and Vein Mining an extremely powerful mining setup.

How do I change the activation key for Vein Mining?

Open the veinmining-client.toml file in your Minecraft config folder to change the activation method. You can switch between sneaking, standing, or a custom keybinding. If you choose the keybinding option, the specific key can be reassigned through Minecraft's standard Controls menu under the Vein Mining category.

Does Vein Mining cause lag or performance issues?

Generally no — the mod appears to be lightweight for normal use. However, breaking very large veins (50+ blocks) on servers with limited hardware may produce brief lag spikes since all blocks are processed in a single tick. You can mitigate this by lowering the max blocks and max distance values in veinmining-server.toml to match your server's capabilities.
