Scott Scovira, BME\u2019s global manager of blasting science, in a media statement. \u201cThe blast design calculator utilises user inputs including burden, spacing, stemming height, sub-drill, hole diameter, bench height and explosive type to determine explosive loads, powder factors and other outputs. It could be used, for example, to investigate potential blast patterns for a greenfield site \u2013 where numerous scenarios may be quickly generated and calculations checked.\u201d<\/p>\n<p>Scovira added that the rules of thumb table \u2013 which summarises surface blast design guidelines \u2013 can be referenced by the user as they access the blast design calculators.<\/p>\n<p>\u201cThe quick calculator includes a BME in-house formula for the target powder factor, as well as calculations related to the volume of rock to be blasted \u2013 either volume per hole or volume per blast,\u201d the executive said. \u201cThere are energy equations to compare different types of explosives based on their relative bulk strength, while hole-charging equations determine the mass of explosives going into a hole and address loading with gassed emulsion products. This helps determine column lengths and stemming lengths \u2013 with gassed and ungassed explosives.\u201d<\/p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>BME launched a Blasting Guide application that enables users to quickly calculate and check blast designs.<\/p>\n","protected":false},"author":92,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-gradient":""}},"footnotes":""},"categories":[369,2857],"tags":[],"_links":{"self":[{"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=\/wp\/v2\/posts\/1178200"}],"collection":[{"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=\/wp\/v2\/users\/92"}],"replies":[{"embeddable":true,"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1178200"}],"version-history":[{"count":1,"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=\/wp\/v2\/posts\/1178200\/revisions"}],"predecessor-version":[{"id":1178201,"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=\/wp\/v2\/posts\/1178200\/revisions\/1178201"}],"wp:attachment":[{"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1178200"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1178200"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/juniorminingnews.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1178200"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
