抄録

One reserves at outcrop of this deposit were estimated previously at 3 million tons, but chance of its development was not given for its low grade. To work on this development, we adopted a high efficiency method of open pit mining, as its production cost is lower than in underground mining. We began the development work in April 1957, and finished it in August 1959. By our plan, production is 1, 000t per day of 23% Fe ore, covering 10 years, and stripping ratio is 0.7. Main, equipment to maintain this production is comprised of 2 power shovels, 6 dump trucks, 3 bulldozers, 1-motor-grader and 9 heavy drifters. Number of miners is only 39.
