Recently, Shenhua Shendong Coal Group Equipment Maintenance Center was approved by China Coal Industry Association to establish “Research and Development Center for Coal Mining Equipment Remanufacturing Technologyâ€.
It is understood that Shendong Equipment Maintenance Center is a specialized maintenance unit responsible for the repair work of all imported mining equipment of the company. It covers an area of ​​1708.7 mu and has a construction area of ​​540,300 square meters. It has maintenance coal mining machine, hydraulic support and scraper. The maintenance capacity of all mining equipment such as continuous mining machines is the largest maintenance base for mining equipment in China. The center undertakes remanufacturing and technology research and development of mine coal mining equipment and components, including: industrial planning, business objectives and strategy formulation, residual life assessment and value assessment of remanufactured products, non-destructive disassembly technology, parts cleaning Research and product remanufacturing of remanufacturing key technologies such as technology, surface repair technology, non-destructive testing technology, failure mechanism of waste products, and remanufacturing evaluation technology.
In the face of the continued sluggish coal market, the maintenance of Shendong comprehensive mining equipment has been greatly reduced, and it is particularly important to carry out equipment remanufacturing business. Through years of research and technical research, the center has been equipped with shearer operating valves and copper-aluminum coupling. Remanufacturing conditions for 14 types of parts such as the device. At the same time, the center also carried out the construction work of the drilling machine drilling box, damper, downhole water treatment system, hydraulic support seal, anchor cable tray, three-machine structural parts, etc., which can fully meet the needs of various mines in Shendong. .
The R&D center was established in the equipment repair center, which is conducive to the important role of equipment remanufacturing in the development of circular economy, the realization of equipment renewal and the promotion and application of new technologies, to achieve the purpose of de-capacity and cost reduction, in line with Shendong’s management philosophy. And the need for talent development.
