Tunnel TNT
by GoZeRuk
Tunnel TNT is a Forge and NeoForge utility TNT block that carves straight tunnels of configurable size and length into terrain.
What it does
A player places the TNT block and the mod generates a tunnel along a chosen direction. Tunnel size, segment length and lining can be set, with optional lights, support pillars, an outer lining cap and structural beams. Mined blocks can be left in place or dropped as items. Up to four tunnel profiles can be saved and reloaded, and an undo function reverses a recent tunnel.
The block offers a three-way vertical mode (off, slope up, slope down), step-count control from 1 to 4, and rail placement with powered rail support, including a longer powered-rail run of 9 and adjustments for slopes and diagonals. Bedrock destruction is off by default, and a creator mode exposes advanced generation settings. Tunnel TNT runs on Forge and NeoForge, is published for 1.20 – 26.1.2, and needs both the server and every player to run it. The code is released under All rights reserved, so the mod is not open source.
Key features
Tunnel shape controls
Tunnel size, length, start offset and segment length are set in configurable steps, from 1 to 100 segments.
Lining and supports
Optional lining, lights with configurable spacing, and structural beams or pillars can be added to finished tunnels.
Profiles and undo
Four profiles save and load tunnel settings, with an on-screen confirmation, and a recent tunnel can be undone.
Rail placement
Rail mode places powered rail along the tunnel, with dynamic spacing on slopes and diagonals and better downhill momentum handling.

Who it’s for: Survival players who dig long corridors for rail or base access, and server owners who want a shared digging tool with configurable limits.
