The PRGR R35 wedge that conforms to new face groove rules is a wedge that has the feel of a putter. The 35degree loft is designed so that the ball will carry 1/4 of the way, and run 3/4''s of the way to the pin. For approach shots that are normally filled with tension, this wedge allows you to comfortably swing as you would with a putter. SPEC

bench angle, the interramp angle cannot exceed the geometrical constraints imposed by the bench geometry. In this case, the bench determined interramp angle is: (1) Now, it is obvious that the bench controlled interramp angle (48°) is less than the angle at which the interramp slope has been determined to be stable (55°), thus the slope

A few weeks ago I made my slopes chart available which gives various angles of slopes depending on how you use them. Very closely related to the slopes are the wedges. Sideways slopes, if you will. Though I''m sure many of you have figured out how to use these two together I thought it would be beneficial to have a chart of wedge angles as well.
WhatsAppعرض المزيدIt can be adopted for all strata conditions. A wedge cut consists of pairs of holes, usually drilled horizontally, that meet or finish close together at the back of the cut so that a wedgeshaped section of the rock face will be removed on blasting. The holes should be drilled at an angle .

Wedge cut Blasthole are drilled at an angle to the face in a uniform wedge formation so that the axis of symmetry is at the centre line of the face. The cut displaces a wedge of rock out of the face in the initial blast and this wedge is widened to the full width of the drift in subsequent blasts, each blast being fired with detonators of

Three different bench stack angles (46°, 52° and 58°) were used for analysis of wedge failure and for rock fall, with combinations of 4 different bench face angles (65°, 75°, 85° and 90°) and 3 different bench heights of, 20m, and 25m evaluated for each. These bench heights correspond to 4, 5 and 6 benches in a stack respectively.
