Shandong Dongping Hongda Mining Co., Ltd. was established in May 2005 with a registered capital of 300 million yuan. The mine is located in Pengji Town, Dongping County, Tai’an City, covering an area of 4.9781 square kilometers, with a total iron ore reserves of 96.349 million tons. The company has more than 800 employees, including 32 technical management personnel, 80 technicians. Since its establishment, the company has actively promoted the construction of ecological civilization, advocated the concept of scientific and green development, and committed itself to building a mining enterprise with safety, civilization, green and sustainable development.

　　Shandong dongping hongda mining co., LTD. Design mining method for underground mining, shaft development, mining method for subsequent filling stage chamber method, designed annual production capacity of 2 million tons. Supporting construction has an annual processing capacity of 2 million tons of mineral processing plant, 600 thousand square meters/year of cementing filling station, living areas and office areas. The main shaft and auxiliary shaft hoist are operated remotely. The two wings of the mine have east and west air return shafts, and the main ventilator is installed with remote operation and on-line detection system of air pressure and air volume. Downhole has advanced and complete safety of "six systems" : monitoring system, personnel positioning system, emergency actions system, communication system, pressure wind self-help system, rescue system of water supply, 4 g coverage, underground roadway, all in a cavern production operation department is equipped with the display terminal, can be real-time control mineral sheers safety production situation.

　　Company committed to the development of the science and technology innovation, building automation, informationization, the wisdom to lead in mines, and shandong is yuan geological prospecting institute, yantai him engineering design co., LTD., shandong university of science and technology to prevention and control of underground water, high concentration of cementation filling, large diameter deep hole lateral caved ore mining method such as signed a strategic cooperation agreement, promote production, study and research of strategic cooperation, actively promote the transformation of scientific research achievements into productivity. The company actively promotes mechanization replacement, mining, excavating all use mechanization, reduce the labor intensity of personnel, reduce the underground operation personnel. With the introduction of CY-UMD6 drilling trolley and the adoption of large diameter and high sublevel lateral caving mining method, the safety production conditions are greatly improved, the production capacity of the chamber and the ore recovery rate are greatly increased, and the production cost is obviously reduced. The introduction of Atlas Boomer1254 medium hole drilling trolley increases the drilling efficiency of medium hole from 100 m/day to 500-600 m/day. The introduction and use of JCTN magnetic separator, a patented product of Shandong Huate Magneto Technology Co., Ltd., has significantly improved the concentrate grade and recovery rate. Some of the main equipment has been automatically transformed, and the real-time monitoring of the main fan, remote operation, unattended air compressor, and remote operation of the main and auxiliary shaft hoist have been realized.

　　The company unswervingly puts into practice the scientific judgment of General Secretary Xi Jinping that "clear waters and green mountains are golden hills and silver mountains", and has always adhered to the concept of not only golden hills and silver mountains, but also clear waters and green mountains.
