The UG2 contract for the Bangalore Metro in India incorporates some 2 500m of twinbored tunnels excavated through hard granite and granitic gneiss of more than 200MPa in compressive strength as well as layers of weathered rock of differing geophysical characteristics and soft residual soil at tunnel horizon. A full face of rock or of soft
Mobile cone crusher plant is usually as secondary crushing machine to process rocks or ores from priamry jaw crusher plant. After cone crusher machine crushing hard crushed stone is fed to vibrating screen to get different size material 05mm 510mm 1020mm 2040mm or some other required size. Vibrating screen is designed to be same level
is perhaps the most instantly recognisable name to tunnellers due to its leading ranges of tunnelling and drilling equipment. The company also possesses expertise in manufacturing crushing and screening equipment ideal for underground operations. All equipment is available as static mobile or semi mobile wheeled or skid mounted.
Formation resulted from the underlying layers of hard rock with the presence of large boulders above the tunnel axis surrounded by weathered soils. operation by 2024 the 43 km TEL will run fully underground The presence of large boulders in the excavation face can adversely affect the performance of the Tunnel Boring Machine

Calcareous Bündner Schists show an EModulus of approx. 38 GPa 26 while standard aggregate rock material like granite exhibits a range of 5070 GPa Gabbro and Basalt even a magnitude of
2. Literature review. Imagebased analysis of rock fragmentation is mainly involved when using mechanical excavation or blasting methods in tunnel engineering and the mining industry .In this method images are captured from the surface of the rock fragments and then manually or by computer fragmented rock distribution is determined .One technique is to use digital image processing
ZongXian Zhang in Rock Fracture and Blasting 2016. Thermal Mechanical Drilling and Tunneling. Thermal mechanical drilling and boring can increase the advance rates of tunneling machines and drill bits. According to Maurer 32 the reduction of the compressive strength of rock from 354 to 138 MPa due to thermal loading would increase the advance rate of a m diameter tunneling
In Tunnel boring machine (TBM) tunneling mechanical screening (scalping screener) is normally the first stage of the processing of tunnel rock. The screener removes rock particles below 16 or 20 mm diameter. This is to remove the high amounts of fines which is created when TBM tunneling in hard rock.
Typically the minimum setting on most primary crushers will be about 4 to 6 inches as noted above. Compressionstyle jaw cone impact crushers and gyratory crushers are most often appropriate as primary crushing equipment types though there can be overlap between primary and secondary crushers as far as suitable types. 2. Secondary Crushing.
The Mixshield technology developed by Herrenknecht is an advance on conventional slurry technology. The support pressure in the excavation chamber is precisely managed using an automatically controlled air cushion. This means that heterogeneous geologies and high water pressures of more than 15 bar can be controlled safely even with very large

Rather than removing rock this machine turns hard unusable farm land rock into soft nutrient rich arable land by crushing it. The rock is smashed by it s hug
A tunnel boring machine (TBM) also known as mole is employed for the construction of tunnels in hard or soft rock strata. The cutting process utilizes the rotation of the cutterhead (geared with disc cutters) and the blade pressure for excavation on the face of rock. Mostly gripper and shield TBMs are ideal for tunneling in difficult rock
and to recommend and identify new strategies to develop new rock breaking technology for Tunnel Boring Machines (TBMs). Tunnel Boring Machine tunnelling mainly depends upon the rock breakage caused by cutters moving on a rock surface in a rolling and sliding motion while under the action of thrust force. The rock breaking behaviour is
