blasting to maximise crusher throughput and minimise crusher blockages. To enable the annual material movement target of 150 million tonne (165 million ton), large rotary drills drill large diameter holes. Historically the production blast designs used subdrill and stemming lengths with standard design factors relative to the hole diameter.

· 4.It requires a relative small capital expenditure particularly if drill and blast services are contracted out. 5.It has design flexibility with respect to varying production volumes, changing rock conditions and producing different rock size gradations. The Chemical Crusher is our breakout opportunity for process improvement.
The tunnels are built with reinforced concrete liner wall by drill and blast of rocks with Q value (Palmstrom et al., 2002) varying from 0.1 to 1.1. The purpose of the analysis is to determine both temporary and permanent stresses in the lining. A plane strain approach with an application of the rock pressures on the sides of the tunnel and the ...

Impact crushers produce high-quality end products efficiently. Impact crushers are named after the method they use in reducing larger blocks of rocks to smaller grain sizes. As the name suggests, an impact crusher accelerates the feed material to high speed and then flings the fast-moving rocks against the walls of the crushing chamber and each ...
Rock hammering is slow, inefficient, costly, and has the same inherent properties of blasting on a smaller scale. Blasting can actually be quieter than rock hammering, and takes much less time. A typical blast duration is usually 1 to 3 seconds, while rock hammering can take over two weeks to displace the same amount of volume incurred by a ...
· If a primary crusher is bottlenecking a site, increasing crusher throughput will lead to a direct reduction in cost per ton. Either more material can be produced for the same fixed cost base, or the same amount of material can be produced using fewer plant operating hours. ... Other AI models can then correlate this with drill and blast ...
