Study on the Vibration Effect of Short Footage Blasting Load on Surrounding Rock-Support Structure of Tunnel

open access: yesShock and Vibration, 2020
In the excavation process of a drilling and blasting tunnel, it takes multiple blasting excavations to form, so it is inevitable to produce multiple blasting impact loads, which will cause certain vibration damage to the surrounding rock-support ...

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Mine hard rock excavation with no blasting

open access: yesRevista del Instituto de Investigación de la Facultad de Ingeniería Geológica, Minera, Metalúrgica y Geográfica, 2009
Drilling and blasting is generally used for fragmenting hard in situ rock in mine excavation. This method however, in addition of being expensive, it causes environmental pollution by noice, dust, vibrations and gases. It may also generate social conflicts with native communities around the mining operation as it disturbs and alters the inhabitants ...

Study on the evolution of rock damage and blasting characteristics of deep tunnel splitting and drilling with explosives

open access: yes工程科学学报
As mineral resource extraction progresses into deeper regions, the in-situ geological stresses within rock layers increase significantly. Consequently, high geological stress becomes a critical factor to consider during blasting operations in deep rock ...
