  • H BLASTING IN SURFACE EXCAVATION - Mining and Blasting

    Figure 9: Hook-up system with Nonel in surface mining Delay Intervals Too short a delay causes the back rows to be initiated before the burden on the front holes has time to break away and to move. This may cause flyrock from rows at the back. 13 Too long a delay may also cause flyrock, airblast and boulders, as the protection from previously fired rows disappears due to too great a rock ...

    In small-scale surface mining including small quarries, jackhammers are in common use but in larger quarries and open pits, various types of mechanised rigs are employed. They drill holes of up to 350mm diameter and lengths up to 60m. Blasting in a mine generally occurs in two phases, primary blasting and secondary blasting. Blasting. Primary Blasting is the activity in which in-situ rock is ...

    avoiding both fines and oversized fragments to optimize the overall cost of mining. In most of the surface mines, blast patterns are established through trial blasts. The blast pattern proposed from trial blast often fails to achieve the required blast results. Thus, it is felt necessary to develop a software for surface blast design based on the methodology proposed by Langefors and Kihlstrom ...

  • Blast Hole Drilling: The Basic Process RPM Drilling

    Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity. The initial hole into which the explosives are packed is known as the “blast ...
