The 4th mining block took the lead in carrying out the plan by concentrating large equipment such as rotary drills on mining benches and keeping them in full-capacity operation while giving priority to earth-scraping.

Other mining blocks consecutively carried out blasting of 30,000 and 50,000 cubic metre earth by making use of effective blasting methods and increased the iron ore production through scrupulous manpower allocation and equipment management and improvement of the existing mining methods.
