—Mine Engineering—
(Deep mine and surface mine)
    Over the past 60 years, the institute has undertaken over 100 projects of master plans of mine area, completed over 500 mine shafts and accomplished over 50 coal preparation plants in more than 20 provinces, cities and autonomous regions all over the country. Among them, there are 29 mines and coal preparation plants boasting a production capacity of 5 Mt/a or above, 14 of which standing out with a production capacity of 10 Mt/a or above.
      The institute has undertaken the design of many large or super-giant open pit coal mines and nonferrous metal mines, registering 6 mines with a production capacity of 5 Mt/a and 3 mines with a production capacity of 10Mt/a. Demonstration projects of strip mine design are available in Xinjiang province, Yunnan province, Hubei province, etc
.
 


  Model for the Construction of Coal Mine throughout the World

 

Bu’ertai Coal Mine of Shenhua Group - the largest deep mine shaft (20 mt/a) and the largest group coal preparation plant (31 mt/a) throughout the world
      The mine is subject to inclined shaft development and is provided with multiple approximately horizontal coal seams. Productive capacity of the is up to 20.0Mt/a through “Three Integrations and Five Continuities” (i.e.three working faces for integrated mechanical mining and five for continuous miners)Continuous belt conveying system is employed in the shaft and the continuous conveyance provided by railless rubber wheeler is used as auxiliary carriage. The coal seam has auto-ignition property and explosive risk. Automatic industrial control system and comprehensive safety monitoring system are set for the mine shaft. Floor space of the industrial plaza is 57.5h㎡.

 

Zaoquan Coal Mine of Shenhua Ningxia Coal Industry Group Co., Ltd.
(10 mt/a)
    The designed production capacity of this mine is 10.0 Mt/a. The mine is developed by inclined shaft, and the construction is divided into two phases in one shared mine compound. For the east-wing area of phase I, belt conveyor is employed for major conveying system, while rails are used for auxiliary conveying system. The production capacity of 5.0 Mt/a is assured by the concept of two full mechanized mining faces in one mine compound. The construction period is 30 months, and it will be able to immediately reach the designed production capacity as soon as it is put into operation. For the west-wing area of phase II, belt conveyor serves for major conveying system, while trackless free-wheeled vehicles are applied to auxiliary conveying system, where non-transshipment conveying is conducted continuously from on the ground to under the shaft. The designed production capacity of 5.0 Mt/a is guaranteed by the arrangement of one large-volume and high-efficiency full mechanized mining face. The construction period is 28 months, and it will be able to immediately reach the designed production capacity as soon as it is put into operation.

 

 

Mine Shaft for the No. 1 Wanli Mine of Shenhua Group (Changhangou Mine)
(10 mt/a)
    It is subject to inclined shaft development, and belt conveyor and railless rubber wheeler are used for the major conveyance and auxiliary conveyance respectively. One and two comprehensive mining work surfaces are respectively set at the initial and later stage. The nitrogen-filling extinguishing system is set.
    With domestic plant and characterized in one work surface for one shaft, the mine is provided with the productive capacity of 10 million t/a.

 

Qipanjing Mine of Mengxi Coal Liquefaction Co., Shenhua Group
(mine shaft: 3 million t/a; coal preparation plant: 4 million t/a)
    
It is subject to inclined shaft development. Two coal seams are exploited with the depth of 1390m , and the sublevel mining and handling is adopted. The mine is provided with full-seam extraction comprehensive mining work surface. For the coal seam has the property of auto-ignition, gas drainage and nitrogen extinguishing system is set.
