During blasting, the  uncontrolled shock wave movement caused damage to  the surrounding rock strata. This results into  additional support cost and time over run to  complete the project. The available controlled  blasting techniques are costly and time consuming  and hence not popular. Thus, vibration based damage  control technique has more applicability and  popular world-wide. This book present the a strong  review of the causes of rock damage and the role of  its influencing parameters on the extent of rock  damage. The mechanism of blast wave propagation and  wave properties are also discussed. The controlled  blasting techniques proposed by different  researchers time to time is also reviewed in  details. The newly developed mathametical model for  controlling the rock damage based on propagation of  blast wave is described which is validated using  number of case studies. To predict the extent of  rock damage, artificial neural network model is  also developed, which may act as an expert system  with large number of training data set.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838387123\"\u003e\u003ch3\u003etheory and practice for engineers and students\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838387123","offer_id":39469285965917,"sku":"9783838387123","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/b3a922c1-9508-4f38-97e2-f342573ca6fa.jpg?v=1768976938","url":"https:\/\/shop.autorenwelt.de\/en\/products\/blast-induced-rock-damage-in-tunnels-drifts-von-kaushik-dey","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
