From: Study on correlation between TBM tailings gradation and granitic gneiss surrounding rock stability
Lithological characteristics of three types of surrounding rock tailing: (a) characteristics of sparsely fissured rock tailings on 20 mm sieve mesh, (b) characteristics of relatively developed fissures rock tailings on 60 mm sieve mesh, (c) characteristics of broken rock tailings on 5 mm sieve mesh.
