Justification of optimal highway slopes at working of mountain-deep opencast mines
The method of technical and economic justification of highway slopes at working of mountain-deep opencast mines was worked out. Physical criteria and choice of optimal highway slopes at carrying up and down of rock mass were justified; technical restrictions of slopes were set. Technological schemes and the method of calculation of transition to higher slopes at working of mountain-deep opencast mines were grounded. Justification of slopes in Chineisky mining enterprise was carried out.
