The prevention of blasting related accidents depends on careful planning and the faithful observance of proper blasting procedures and practices. Even the slightest abuse or misdirection of explosives can result in serious injury …
However, the blasting practices with the most sophisticated modern drilling equipment have surpassed the rule of thumb. The dimensional parameters in such cases must be decided on the basis of assessment of rock mass and geo-mining conditions.
This paper presents the final wall blasting practices at Eldorado Kisladag Gold Mine in Turkey. Benchmark and improved wall control designs were explained in detail.
Drilling and blasting is one of the most dangerous mining processes undertaken. Degrees of automation enable drill rigs to do much of their work independently, effectively removing people completely, or lessening workers' exposure to hazards such as dust, noise, vibration and, crucially, explosives. In countries where labour is expensive ...
The drill and blast technique is the most common method of mining in open-pit mines. It is often used when a deposit can be accessed from the surface. The process uses a drilling rig to create a series of drill holes before explosives are detonated in these holes to break the rock into small pieces that are removed during the blasting …
