Over 7 million yards of rock excavated for two power projects
80% of Sweden's hydroelectric power plants are underground with capacity of 1,000,000 kw; they required moving of 10,000,000 cu yd of rock; largest are 285,000 kw Kilforsen plant and Stornorrfors project with four 130,000 kw electric units each; both projects will have 60 ft wide rock chambers; 170,000 hp Francis turbines installed; data on headrace tunnel, excavation of rock chamber and tailrace tunnel.
