The birth of the first digital coal mine in China

The first phase of the project of Liuzhuang Coal Mine of SDIC New Energy Co., Ltd. was completed and trial production, which marked the birth of China's first digital coal mine.

The reporter saw in the monitoring room of Liuzhuang Coal Mine System that Lu Dexin, the vice president of China Coal Industry Association, dialed the mobile number of the “9229” miner Xia Chengqun at 800 meters through the PHS. The screen of the digital monitoring room was clearly Shows his operation positioning and the time of each positioning. Every miner in the mine carries a PHS phone and keeps in touch with the ground.

Liuzhuang Coal Mine is the first large-scale well-type mine built under the new situation of national energy strategy and approved by the state to be built in the Lianghuai coal base. Construction started in March 2003, according to “new, innovative, fine, The high-level construction idea has realized the modernization of technical equipment, the digitalization of mine management, the culture of enterprise managers, the ecologicalization of resources and environment, and the essentialization of safe production, which has become a successful example of coal mine modernization in the new era.

Liuzhuang Coal Mine Construction pursues refined management, relies on informatization to improve the level of refined management, and realizes the automation of production process, the informationization of management processes, and the digitization of system monitoring. The mine display and monitoring center projection display system is composed of 42 single-screen 67-inch DLP large screens. The whole display system is divided into two parts: display projection unit and video control. It has high brightness, high definition and high intelligence. The system enables real-time demonstration, monitoring and intelligent management of on-site control information and video surveillance images, enabling accurate and rapid analysis, helping production managers to master production conditions in a timely manner, and achieving the main production workshops and underground The electromechanical diverticulum is unattended, the information exchange of underground and ground, production site and management platform realizes centralized control of the whole mine. It is the first in the national coal industry to realize the integration of production scheduling, monitoring and execution, and become a high automation and high information. Digital mines that operate at high efficiency.

The construction of Liuzhuang Coal Mine reflects high efficiency on the basis of high technology and high standards. The comprehensive integration of financial UF software, ERP system, operation office system, OA office system and operation automation control system has greatly improved the operational efficiency of production, operation and safety management. The underground central belt conveyor is a DX series steel cord conveyor belt conveyor with a distance of 691m and a belt speed of 3.64m/s. It adopts the American Rockwell CST controllable soft start mode, which can realize double S-type starting curve starting and improve coal transportation. effectiveness. The mine railway loading station is a fast loading station with 5,000 tons of coal per hour. Using radio frequency technology, the full implementation of the "one card" project, a small RF card to achieve intelligent management of attendance, access control, consumption, power control, water control and other functions.

The completion and commissioning of Liuzhuang Coal Mine will fully promote the strategic goal of the new mining area to achieve the annual output of 35.9 million tons approved by the National Development and Reform Commission. A modern coal mine with scientific and technological innovation, ecological environment protection and humanistic harmony has become a new bright spot in the economic development of the northern region.
