Drop Mining Physics

Tags: gameplay, physics, building

The stability system tracks support from the ground up. Remove too much support and the ceiling collapses, taking you with it. Build mines like real structures.

Rules of stability

• Every block checks support strength; long spans without pillars weaken quickly.
• Gravel and sand collapse easily; ore veins hidden in them can trigger cave-ins.
• Frames count as support but offer less strength than concrete or steel.

Safe mining pattern

• Dig a 3x3 shaft, then branch tunnels no longer than 10–12 blocks before adding a pillar.
• Use wood or concrete pillars every 6–8 blocks, tied into the ceiling with plates or beams.
• Place support before removing load-bearing blocks; never hollow out the floor below your own pillar.

Recovery plan

• Carry frames to brace collapsing ceilings quickly.
• Keep a second exit in case debris blocks the main shaft.
• If running mods that alter stability, test them in a creative world so you know their limits.
