Brief introduction of Mahuangliang Coal Mine

Mahuangliang Minefield is located at the junction of Maowusu Desert and Loess Plateau in northern Shaanxi. Its landforms are loess beams and river terraces. The terrain is relatively flat, the geological structure is simple, and there are no faults and folds in the area, which belongs to a low gas mine. The average buried depth of coal seam is between170-200m. The minable seam is 2 layers. From top to bottom are No.3 coal seam and No.3-1coal seam. The main coal seam is No.3 coal seam. The thickness of coal seam ranges from 7.55m to 1 0.36m, with an average thickness of 9.06m and an inclination angle less than1degree. The coal seam structure is simple and the coal quality in the area is excellent. This coal belongs to high-quality power coal with low ash, low sulfur, ultra-low phosphorus, good coking performance and high calorific value, and is also an ideal choice for gasification, liquefaction and coal water slurry.

The way of mine development is two vertical shafts, a fully mechanized working face is arranged, longwall mining method is adopted, the roof is managed by full caving method, and comprehensive mechanized coal mining technology is adopted. The equipment configuration is all localized, the main transportation adopts belt conveyor, and the auxiliary transportation adopts a comprehensive transportation mode combining rail and trackless. The mine adopts extraction ventilation mode. Modern network monitoring, ventilation and setting information system ensure the efficient, safe and healthy development of the mine.

The mine entrusts China Coal Xi 'an Design Engineering Co., Ltd. with Grade A qualification of general contracting design.

Coal mine construction and production management adopt international professional management mode. Entrust a professional company to carry out construction supervision, and the professional company will carry out the project budget and final accounts. Set up an expert advisory group to conduct professional and technical checks. Hire senior managers to plan, construct and manage mines. In the process of mine production, the management mode of separation of production and management is implemented. Strive to achieve lean organization and management. Production management is clear and simple. The ground layout is simple and distinctive. Strive to build the Mahuangliang Coal Mine into a model mine for local coal mines in Yulin City.

Mahuangliang Coal Mine adheres to the concept of building mines to enrich the people, vigorously promotes the construction of high-standard and high-quality coal mines, and all employees work together to build Mahuangliang Coal Mine well. On the basis of people-oriented and harmonious development, we will gradually form a unique corporate culture and create a safe and harmonious working environment for employees. Keep pace with the times, blaze new trails, build a first-class modern mine, build a local mine brand in Yuyang, and make contributions to the sustained and healthy development of Yulin coal industry.
