Although there have been  significant developments in blasting, application of  this technology for rock excavation induces damage  to the remaining rock mass. The rock mass damage  problem will increase manifold if the blast loading  is applied repeatedly as compared to single episode  blast rounds. The damage can easily extend a few  meters into the rock mass and the deteriorated rock  mass can give rise to serious support design  problems in tunnels and caverns. This book deals  with the quantification of blast damage as a  function of rock mass quality (Q), which can be used  for assessment of damage levels, in case of repeated  exposures of vibrations. A correlation between  damage and shear wave velocity was also established.  The book also illustrates the effect of joint  orientations on blast damage to enhance the safety  and stability of underground excavations.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843393188\"\u003e\u003ch3\u003eAPPLICATIONS TO CIVIL ENGINEERING PROJECTS\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843393188","offer_id":39497140994141,"sku":"9783843393188","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/45a3b2f4-02b8-4726-a817-f58026a9498f.jpg?v=1776487770","url":"https:\/\/shop.autorenwelt.de\/products\/blast-induced-rock-mass-damage-in-underground-excavations-von-more-ramulu-und-t-g-sitharam","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
