Abstract:

Abstract: Taking thin coal seam mining for example in the large open-pit coal mine, the article presents three kinds of feasible mining technology. On the basis of comparing the technology economy of the schemes, the mines establishes the gray math model, carries out optimization choice on the schemes, and finally determines thin coal seam mining adopting open-pit mining machine- front loader-truck mining technology. The mine uses the calculating formula of mining and transportation equipment production capacity to calculate equipment number.
