ABB Electric Supplies the Largest Mine Hoist System in China

ABB, one of the world's top 500 companies, recently provided the largest hoisting system in China for the Majialiang coal mine under the Shanxi Datong Coal Mining Group Co., Ltd., and for the first time in the industry realized the advanced application of "full load half speed" of the mine hoist, ensuring that Coal production is safe and efficient.

"The safe and efficient production of coal has always been an important issue in the global coal mining industry and has become more important in China. China's coal mining companies have also raised the safety and efficiency of production," said Born, head of ABB's Process Automation Business Unit North Asia and China. With higher requirements, ABB is the technology and market leader in the mining and mining industry, and the only supplier in the world that can provide a full range of mine hoist equipment.In China, we hope to provide advanced equipment for more industrial customers. Safe and efficient coal production contributes.”

The mine hoist is an important mechanical system for coal production. The motor drives the steel wire rope to lift the hoist in the mine and complete the coal transportation task. The modern mine hoist has a large amount of lift, high speed, and high safety. It is a highly automated heavy mining machine.

ABB has provided two sets of elevator systems with the largest lifting capacity in China for the Majialiang coal mine, including a host, ACS6000 medium voltage drive system, electric motors, electronic control equipment, gate control equipment, lift containers and a full set of equipment and related technical services. ABB hoisting equipment has a drum diameter of 5.7 meters and a payload of 45 tons. It has a lifting capacity of 1,520 tons/hour and ranks first in the country in terms of lifting capacity, effectively improving the working efficiency of coal mines.

In the Majialiang coal mine project, ABB has also achieved the advanced function of “full load half speed” of the hoist for the first time in the world. When the hoist is running, the ACS 6000 medium voltage drive system in the system uses two independent rectifier units and inverter unit equipment to power the entire system motor. Under normal circumstances, the two sets of rectifier units and inverter units work independently, and the full load coal mine hoist can operate at full speed. However, once a circuit failure occurs in the mine and causes one of the equipments to stop operating, the entire system can quickly switch to emergency mode and use another set of equipment to work independently. This ensures that the fully loaded hoist continues to operate at half speed. Under normal circumstances, in the face of such problems, mine hoists that have not adopted ABB's “full load half speed” technology can only completely stop working and wait for maintenance. The increase in downtime also seriously affects the safety and continuity of coal production.

Datong Coal Mining Group Co., Ltd. has a total assets of 75 billion yuan, 200,000 workers and 54 pairs of mines. The coal output exceeds 100 million tons for many years. Majialiang Coal Mine is a key construction project in Shanxi Province. It is located in the southern part of the Weinan Mining Area, one of the country’s planned large-scale coal production bases. It has a designed annual production capacity of 12 million tons of raw coal and a maximum output of 15 million tons. It is currently the largest vertical shaft coal mine in Asia. .
