Nine Sandvik underground drilling rigs and rock drills are being used to cut tunnels for India’s Parbati Hydroelectric Project (Stage III), under construction in the Himalayan foothills at Himachal Pradesh in India.
The civil teams of Jager-Gammon India and Larsen & Toubro-Patel are carrying out the work using Sandvik rigs and rock drills for drilling and bolting.
Jager-Gammon is using four Sandvik Axera T08-290 rigs and an Axera T08S- 290C, while L&T Patel has four Axera T08-290 rigs. The machines are equipped with Sandvik drill tools.
Tunnelling in the Himalayas is a notoriously difficult process, due to the varied nature of the rock encountered, the instability of some areas, and seasonal snowfall and rain.
The project is being undertaken by the National Hydroelectric Power Corporation (NHPC) in conjunction with the Himachal Pradesh government.
