04 Jul Framework type of blasthole charge design considering lithology delivery
New density out of geological exploration boreholes is amongst the main angles for blasthole costs construction construction. As a result of the low density of geological exploration boreholes, it's impossible to get the great time hole stone formations' delivery correctly. Into innovation and you can application of wise drilling rigs, the fresh lithology shipments studies of blasthole can be correctly acquired, and you can a great blasthole costs construction design method according to research by the lithology shipment is recommended. New blasthole lithology research gathered from the intelligent fucking rig was split into seven classes with regards to the rock firmness, and adjacent strata with the same lithology is actually joint and you will split to the a couple of sets of silky stones and difficult rocks. With respect to the rock stratum collection research of blasthole and you may the product explosive usage of every type away from lithology, the volatile matter and charges size required for this new soft-rock group and the hard-rock category is calculated, correspondingly. Eventually, the new blasthole charge design is created depending on the occurrence and you may charges position of the difficult stones.
