dc.description.abstract |
At present, Sri Lanka is inveslheavily on the development of the country's infrastructure.,
facilitating the vast demand for construction materials particularly, aggregate metals. Blast
fragmentation is one of the most important aspects in open pit blasting. Blasted rock should be easily
loaded and transported and the rock fragments should be adequately pre-conditioned (i.e. weakened)
in order to reduce the energy requirements in down-stream processes such as, crushing and grinding.
In Sri Lanka, the geological parameters of rocks vary throughout the island. Currently, there is a large
number of metal quarries and mining activities operating all over the country, but the lack of
optimum blasting practice and specific charge selection is a drawback to achieve the optimum
benefits.
In this research, an investigation on specific charge values have been carried out for the required level
of fragmentation in quarrying industry and tunneling practice throughout Sri Lanka depending on
geological parameters varying from region to region. Rock sample collection from various geological
locations, determination of rock strength and hence, building-up a relationship between rock strength
and specific charge values, experimentation of a fragmentation model have been carried out. |
