Other people's footage, not advice: how someone else dives here says nothing about what suits your team. Dive within your training.

The dive

Visibility is 10–15 m in summer and up to 40 m in winter. In summer the water is 24 °C at the surface, 20 °C at 30 m and 16 °C at the bottom; in winter 16–17 °C.

In the mine silt can bring visibility to zero and bubbles collect under the ceiling; narrow fire doors and vertical shafts. At 915 m altitude: adjust your dive planning.
Profile and sections

Visibility is 10–15 m in summer and up to 40 m in winter. In summer the water is 24 °C at the surface, 20 °C at 30 m and 16 °C at the bottom; in winter 16–17 °C.

This was an asbestos mine until 1972. It flooded when pumping stopped and was rehabilitated in 2002.

Depth and profile
Open pit of ~110 × 50 m, to ~55 m. Eight connected mine levels (including ~38, 48 and 70 m), explored to 186 m; the mine entrance at ~18 m.
Intro level
The open pit (to ~55 m) with training platforms at 5, 9 and 30 m is open water; the mine drifts start at ~18 m and need cave certification (or a cave course).
Configuration
Human-sized drifts (~2 m high, 1.5 m wide) with vertical shafts and narrow fire doors: every configuration, with good trim (estimate). Deep levels on trimix.
Gas
Trimix from 40 m
