E 21 D

 SHAFTS; TUNNELS; GALLERIES; LARGE UNDERGROUND CHAMBERS (soil conditioning or soil stabilising materials C 09 K 17/00; drilling or cutting machines for mining or quarrying E 21 C; safety devices, transport, rescue, ventilation or drainage E 21 F) [2,6]
 

Notes

(1)

 This subclass covers methods or apparatus for making or lining tunnels, galleries or large underground chambers, using underground mining methods only, i.e. not involving disturbance of the ground surface. [6]

(2)

 This subclass does not cover underground spaces made by foundation engineering, i.e. involving disturbance of the ground surface, which are covered by subclass E 02 D. [6]
