    • Abstract
  • A phosphate mine is a new underground mining mine, which belongs to a gently inclined medium thick ore body. The original design used the upward horizontal stratification filling method and the upward approach filling method for mining. In view of the large amount of cutting work, complex process, poor safety, low production capacity and high labor intensity, it is difficult to meet the requirement of 5 million t/a production capacity in the mine. Through a comprehensive study of mining technical conditions and actual mining production, it is determined that the layout of the mining area is adopted, and the pre-control of the middle and deep hole empty field is followed by the method of filling and filling mining and the mining method of the excavation machine. The mining operation is carried out using large-scale trackless equipment. After optimization, the cutting project was reduced, the mining process was simplified, the operating conditions were improved, and the labor intensity of workers was reduced.
