This edited volume includes all papers presented at the 22nd International Conference on Mine Planning and Equipment Selection (MPES), Dresden, Germany, 2013. Mineral Resources are needed for almost all processes of modern life, whilst the mining industry is facing strict requirements regarding efficiency and sustainability.
in surface and underground mines. However, the total number of injuries per one million employee-hours for underground US coal mines in the last decade is three to four times higher than for surface mines. The difference between the injury rates per one million tons of coal production further demonstrates this point underground mining is less
The largest underground mine is Kiirunavaara Mine in Kiruna, Sweden. With 450 kilometres (280 mi) of roads, 40 million tonnes of annually produced ore, and a depth of 1,270 metres (4,170 ft), it is also one of the most modern underground mines.
The Kiruna mine is the world’s largest underground iron ore mine and its 11 ABB mine hoists make it the largest hoisting plant in the world. ABB is currently upgrading the four underground hoists and has supplied a seventh surface hoist to enable LKAB to boost production capacity by 25 percent to 33 million tons of crushed ore a year.
Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of
Underground production is estimated to be 44.1 million tons of ore averaging 0.55 percent nickel and 0.16 percent copper. Enhancing its opencast operations with an underground mining could potentially increase the Kun-Manie mine site by at least 19 percent.
We began operation of our first longwall mine, M Class #1 Mine, in the first quarter of 2012 and our second longwall mine, Viking Energy, at the end of the second quarter of 2014. Surface Infrastructure and Overall Characteristics. Productive Capacity with two longwall systems: 15 million tons per year; Coal Production: 14.5 million tons in 2018

Teghut Mine is a closed copper and molybdenum open-pit mine in Armenia's northern province of Lori in the village of Teghut with deposits valued at US$15.5 billion (in 2010). In December 2014, Vallex Group launched production operations at the mine, which is a US$380 million project.
Completed underground mine construction $2.3 million under and 2 months ahead of schedule against a $22 million budget Excavated the first aggregate mine declines in the U.S.A using a Voest-Alpine ATM105 Roadheader Attained 1.1 million tons first year production in drill and blast, roomand pillar mining operation
City Water, Light and Power (CWLP) the largest municipally owned utility in Illinois is a major customer, with Viper Mine supplying 1.4 million tons of coal to the utility in 2010. CWLP's contract with ICG runs through 2020 at a cost of about $38 per ton.
CHAPTER 11 Mining Technology The Federal Coal Leasing Amendments Act over all underground mines in the United States, the recovery ratio is63 percent. Sur- face mines, troduced at Carbon No. 1 Mine. This system will be the highest longwall unit (14 ft) in the West.
The mine's planned annual throughput was 1.5 million tons of ore which would produce 265,000 tons of lead concentrate, 110,000 tons of zinc concentrate and 750 tons of silver. A Fluor subsidiary worked on design and procurement of equipment for primary crushing, autogenous grinding, differential flotation and tailings disposal, together with the regrind, leaching, dewatering, handling and
Outside the Soviet Union and the socialist countries, there were in 1970 more than 180 mines with annual production of greater than 1 million tons; of these, 34 mines produced more than 3 million tons annually. The largest mine is the Kiruna Iron Mine in Sweden, which in 1973 produced 27 million tons.

use of operations research in mine planning, covering work on both underground and open-pit mines, and multiple horizons (from day-to-day decision-making, to mine design and long-term planning).We restrict our attention to the short-term planning of open-pit mines, with horizons of at least one week to at most one to two years.
There are 22 open cut mines ranging from those with small capacity of hundred thousand tons up to three million tons and about 23 underground mines ranging from small capacity up to 2.5 million tons, plus a number of underground mine projects. Vinacomin is the owner and major shareholders of minerals mining businesses including:
The Iron Mountain Iron Mine (originally the East Vulcan Mine) was a working mine producing about 22 million tons of iron ore from about 1870 to 1945 when it closed. The ore was taken by railroad to ports on Lake Michigan where it was loaded on freighters and taken to the steel mills in the Midwest.
