Geometry, loading and timing characteristics are  given for 35 production blasts and three single  blastholes. Face movement was measured in eight of  those blasts from targets hanged in front of a  blasthole on the highwall. Vibration data recorded  with seismographs around the block at both near and  far field range are provided for 23 of such blasts  and the single blastholes. Fragmentation in the  hopper of the bin from images is also monitored. The  most outstanding models in the literature for  assessing fragmentation, vibration and face movement  are applied. Some of these models show poor  performance, for instance Kuz-Ram model, while  others like the Blair-Armstrong''s Fourier model for  predicting the mean particle velocity spectra  provide fairly good predictions. Engineering  formulas are derived for predicting the face  movement, fragmentation and vibrations. Finally the  energy balance is calculated for eight blasts in an  attempt to guide blast design.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838328782\"\u003e\u003ch3\u003eRock movement, vibrations, fragmentation and energy\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838328782","offer_id":39498893492317,"sku":"9783838328782","price":68.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/8db3b0e9-e302-4a36-8bce-9c60bdc5be81.jpg?v=1769841558","url":"https:\/\/shop.autorenwelt.de\/products\/monitoring-and-control-of-quarry-blasting-von-pablo-segarra","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
