efficient use of the explosive energy in the blast. Benches may be designed and carried forth with more than one face so that simple blasting patterns can be used to remove the rock. In the illustration that follows (Figure 8-4) shows a typical bench cut with two free faces and fired with one delay per row.
Jun 29, 2016· Blasting operation, the initial step in open-pit mining, may break the ores into fragments so that they can be mined and loaded by excavating equipment. However, this operation might create environmental impacts such as air overpressure, ground vibration, fly-rocks, and back-break around the blasting zone [1–3]. Blast casting in open cast ...

The open-pit mining cycle includes drilling ore and waste rock, loading drill holes with explosives, blasting, ore loading and hauling to stockpiles for processing, waste rock loading and hauling to the waste rock storage pile. Occasionally, drilling and blasting ore is not required and can simply be removed by what is known as free digging.

Nov 01, 2018· Drilling and blasting are the two most significant operations in open pit mines that play a crucial role in downstream stages. While previous research has focused on optimizing these operations as two separate parts or merely in a specific parameter, this paper proposes a system dynamic model (SDM) for drilling and blasting operations as an interactive system.

Apr 17, 2013· For slope monitoring, you shouldn't have problems with the blasts affecting your equipment. With blasting in the pit bottom and extensometers near the pit crest and prisms scattered around the slope, the equipment should be well out of harms way. It would be a stretch for flyrock to damage your equipment. The blast would have to go terribly wrong.
