SnapshotZhungeer mining complex includes two of China’s largest open-pit coal mines, namely Heidaigou and Haerwusu, and supportive preparation plants.

The Heidaigou and Haerwusu open-pit coal mines took the lead in employing the BeiDou positioning system and the intelligent hole siting system in blasting operations and achieving active safe driving functions such as automatic precautions and intelligent braking by relying on safety guarantee systems. Such digitalization efforts have enabled the coal mines to significantly save human labor and enhance production safety.

Summary:

The Zhunge'er Coalfield is located in the Inner Mongolia Autonomous Region, along the northeast portion of the Erdos Table Syncline. Basement rocks to the stratigraphic sequence are dolomites of Ordovician Age approximately 350 m deep.

Mineable coal lies in the Carboniferous Period's Taiyuan Fm. The Taiyuan is the lowermost coal- bearing formation in the coalfield containing coal seams Nos. 6 through 10. The formation averages 60 m in thickness and is divided into three distinct sections. The No. 6 Seam is the target seam of the Heidaigou Opencut Mine. Within Heidaigou's mining rights area, the No. 6 Seam is relatively consistent, ranging in thickness from 20 m to 30 m. Portions of the coal seam are extensively weathered (oxidized) along the southwestern boundary of the mining right area. The No. 6 Seam is relatively complex in composition and is further subdivided into six subseams. Structure is dominated by a northeast trending anticline; seam gradients generally range from 4° to 10° according to localized structural features. Depth of cover ranges from 40 m to 350 m in the coalfield and typically ranges from 100 to 150 m in the mine plan area. China Shenhua's Chengpo Mine of the Wanli Mines unit is proximate to the Heidaigou Mine in the No. 6 Seam.
