Nanfen iron mine. Nanfen open pit iron mine, located in Nanfen district of the Liaoning province, China, is approximately 500m deep. It is one of the largest openpit metal mines in China. Nanfen open pit mine is owned and operated by Benxi Iron and Steel Corporation Benxi Steel. The mine produced more than 100 million tonnes of iron ore in 2011.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 39pit39, and
The Raspadskaya mining operation consists of two underground mines, namely Raspadskaya and MUK96, and one openpit mine called Razrez Raspadsky. Coal Company Raspadskaya is the owner and operator of the mine. Coal mining at Raspadskaya was started in the late1970s. The mine produces 100 coking coal.

Still, coal production from surface mines in China is relatively very small compared to production from underground mines considering that China39s total coal production in 2010 is 3.2 billion metric tons BP, 2011. In comparison, in India about 85 of the total coal production of 506 million metric tons in 2009 is from surface coal mines.
Large stripping machines with excavating wheels used in surface coal mining are employed in other types of openpit mines. Water inflow was a very important problem in underground mining until James Watt invented the steam engine in the 18th century. After that, steamdriven pumps could be used to remove water from the deep mines of the day.
Owned and operated by Shenhua Group, the Haerwusu mine began production in October 2008, with development costs at approximately 1.1 billion. The giant openpit mine is estimated to have a reserve life of more than 75 years, making it the number one coal mine in China.
Alberta is cancelling blanket environmental protections that have been in place since the 1970s and making it easier to develop openpit coal mines in some of the province39s most ecologically
Given the conditions of residual coal from the boundary of a flat dipping openpit mine, which uses strip areas mining and inner dumping with slopecovering, we propose an openpit and underground integrated mining technology for residual coal of end slopes.
The streets of Dalianhe, in China39s frigid northeast province of Heilongjiang, are lined with black snow. The town is home to one of China39s largest openpit coal mines.
Coal seam that is thinner than a certain value is defined as thin coal seams TCS. It commonly occurs in China as it covers 84.2 of the mining area. This situation is even severe in Chinas large surface coal mines, in which TCS accounts for 1050 of the total reserve. Most TCS cannot be feasibly mined due to the working conditions of commonly used mining equipment.
The Hei Dai Gou or Heidaigou, an openpit coal mine also located in the middle of Zhungeer coal field in the Inner Mongolia Autonomous Region of China, is estimated to contain 1.5 billion tonnes of recoverable coal reserves. The mine is located 150km southwest of the Ordos city and has a planned mining area covering 42km.

Chinese power company State Power Investment Corp operates three 10 Mty class open pit mines in Huolinhe, Inner Mongolia, namely the South Coal Mine, the North Coal Mine and the Zhahanur Coal Mine. After nearly a year of planning and consultation, recently, the South Coal Mine and Chinese mining truck automation major Beijing Tage Zhixing Technology Co Ltd Tage Idriver jointly conducted a
Cypher was recently provided with an abstract of a study conducted on an EarthZyme haul road application at an openpit coal mine in Xilinhot, China, by Shenhua Beidian Shengli Energy Co. Ltd.. Following the success of a demo road in 2013, the mining operation built an additional 10km of EarthZyme haul road in 2014.
