aug 20, 2018 course outcomes: drilling and blasting is primary operation in any mining organization, student understands various methods of drilling, design and selection of drilling methods. knowledge about explosives and blasting techniques makes student confident in design of blasting
stope mining blocks of 25-m maximum length are planned to be mined before backfilling. drilling: the drilling is performed from the top level. blasting: for blocks located at the extremities of the orebody, a raise is used as the initial opening. the subsequent blocks are blasted against the unconsolidated fill in order to create a free
oct 15, 2020 different mechanised drilling machines are proposed for each of these activities. support drilling would be performed by up to two support drilling rigs capable of drilling long holes for installation of cable bolts and other ground support bolts. short hole drilling would be performed by double boom drill-rigs
the p&h rotary blasthole drills are productive solutions for all mine types. when you need to meet your drilling and blasting needs at the lowest cost per meter drilled, these powerful and reliable systems make p&h drills your best choice.
jun 10, 2020 mechanised raise drilling should however be considered a viable drilling application for raise boring in massive mine applications. slot raises refer to relief holes within a stope, intended to provide void space for blasting, thereby allow expansion of the blasted rock and to improve fragmentation.
mechanised rigs are employed. they drill holes of up to diameter and lengths up to 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 broken in both development and stoping and in surface mining by drilling holes in the rock,
mining companies on a global basis have been looking for a mechanised, continuous alternative to the labour intensive drill and blast batch process for decades. several companies have tried to cater to this need, but no one technology has provided the silver bullet as of yet.
