An Algerian Coal Mine Inspection Delegation Investigates the Intelligent Demonstration Working Face of Thin Coal Seams Constructed by China Coal Technology and Engineering Group

Recently, an Algerian coal mine owner accompanied by his team paid a visit to the intelligent coal mining demonstration working face of thin coal seams in Yangcun Coal Mine, which was constructed by China Coal Technology and Engineering Group(hereinafter referred to as “CCTEG”), for a tour and exchanges. Thorough investigations were carried out regarding the latest scientific and technological equipment of the intelligent working face of thin coal seams developed by CCTEG, intelligent applications, and the underground working-face production site of CCTEG's intelligent working face of thin coal seams. 

The 4703 thin-coal-seam working face in Yangcun Coal Mine is equipped with a coal shearer, scraper conveyor, and intelligent electro-hydraulic control system developed by CCTEG. This working face has realized highly intelligent and precise control during the mining process through the multi-parameter coupling cutting and mining mode, effectively coping with complex geological conditions and significantly enhancing the mining efficiency and safety. At present, this working face has achieved a continuous monthly output exceeding 90,000 tons and reached the annual production goal of one million tons under the thin coal seams, and has become a benchmark for intelligent mining in the coal industry.

During the visit, the inspection delegation learned about the background and achievements of CCTEG's intelligent construction of thin coal seams through a short video. Subsequently, they visited the ground operation island and viewed the efficient coordinated operation of various intelligent coal mining equipment of the intelligent coal mining working face.  In-depth investigations were also conducted on the operating mechanisms of the automatic control system, remote monitoring platform, and production scheduling system. In consideration of the geological conditions of Algerian coal mines, the delegation placed particular emphasis on the technical feasibility of the complete set of fully mechanized mining equipment for thin coal seams in Algerian coal mines and engaged in exchanges and analyses with the accompanying technical personnel concerning its future application. A coal mine owner stated: "The intelligent coal mining technology of CCTEG indicates the direction of future coal mine production. The intelligent and automated working face not only improves production efficiency but also effectively ensures production safety. We are looking forward to introducing these technologies and equipment into Algerian coal mines to further elevate the mining level of Algerian coal mines."

The visit of the Algerian delegation has not only demonstrated the remarkable achievements of CCTEG in the intelligent development of coal mines and the field of complete sets of equipment but also provided a new development opportunity for future cooperation.

Relevant personnel from the International Engineering Company and Tianma Intelligent Control Company participated in the investigation and exchanges.
