The Musan Mining Complex has increased the concentrated iron ore production by over 1.2 times and the overburden removal by over 1.3 times this year as compared to last year, while producing over 30 000 tons of more iron ore.

The complex carried out its concentrated iron ore production and overburden removal plans, which have been set higher than last year, and made substantial preparations for entering the next stage.

In particular, it focused efforts on enhancing the role of talents so that mass-based technical innovations could lead to successful results in production.

The open branch mine in charge of the preceding process introduced rational methods to speed up tunnelling and made preparations for a 2.5 million-cubic-metre blasting, while further increasing the iron ore production. In the meantime, mining area No. 4 fulfilled its first half-yearly plan by June 18.

The overburden conveyor station ensured the normal operation of the facilities, including a large cone crusher, by introducing a technical innovation plan for removing overburden in large quantities, and the ore transport station and the vehicle repair branch factory set up a proper repair base and secured spare parts to maximize the operation rate of large trucks. Ore transport workshop No. 7 fulfilled its first half-yearly national economic plan by June 15.

After carrying out a 650 000-cubic-metre blasting early last January, the complex succeeded in blasting 700 000 cubic metres of earth on June 23.

Having set the site for the blasting in mining areas No. 1 and 2 and the August mining area of the open branch mine, they completed an optimized design for raising the blasting efficiency through dozens of rounds of field surveys and technical consultative meetings.

The technical team of the complex invented and introduced a new technical innovation plan which can increase the lifespan of bit heads by 2.5 times and provided a sure guarantee for increasing iron ore production by overfulfilling the plan for drilling blast holes every day.
