application of softwares for Drilling and Blasting
Podzemni radovi, 2019Co-Authors: Stefa Milanovic, Laza Kricak, Milanka Negovanovic, Nikola Simic, Jova MarkovicAbstract:Nowadays, software is increasingly used in mining through the exploitation of mineral raw materials, mine design, in performing various field operations, etc. Among mining software, there is software for specific mining operations such as Drilling and Blasting operations. These processes are very important in the exploitation of solid mineral raw materials because they represent the cheapest and most effective form of rock mass fragmentation. Through the Paper, some of software is presented in the combination with modern technologies that are in use all over the world which have brought great advantages in Drilling and Blasting operations.

quantifying the difficulty of tunnelling by Drilling and Blasting
Tunnelling and Underground Space Technology, 2016Co-Authors: Marilena Cardu, Jacopo SeccatoreAbstract:This study deals with industrial trends in tunnelling by drill and blast (D&B). We perform a statistical analysis of accumulated experience from the 1950s to the modern day to provide advice for proper project management in tunnel driving. The basis of the study is a wide database of tunnel blast schemes. This database is made of excavation parameters, and considers two main families of blasts: with parallel hole cuts and with inclined hole cuts. Such parameters are analysed by means of statistical regression. Correlations are shown. We present a general curve of correlation between tunnel sections and specific Drilling and specific explosive consumption. We show how pull efficiency cannot be correlated to a single parameter, and how tunnelling by D&B needs to be treated as a complex system. Finally, we propose a method for quantifying and classifying the difficulty of tunnelling. The deviation of specific Drilling (SD) from industrial average trend is used as an indicator of difficulty: easier when SD is lower than average, and more difficult when SD is higher than average. We show how such deviation can be preliminarily associated with lithotypes. This provides to designers and cost estimators a tool of a first approximation for D&B cost prediction at the pre-feasability and feasibility stages of a tunnelling project.

dynamic research on the minimum rock covers of subsea tunnel construction using Drilling and Blasting method
Rock and Soil Mechanics, 2006Co-Authors: Li ShucaiAbstract:Ascertaining the minimum rock covers of subsea tunnel is important to reduce project cost on the conditions of subsea tunnel safety.Researching the dynamic influence of tunnel Blasting construction on the cover rock mass is necessary to the minimum rock covers.The effect of subsea tunnel construction using Drilling and Blasting method to overlaying strata is analyzed through FLAC3D numerical simulation.The influence of different subsea tunnel level and charge weight on the interface of overlaying strata is analyzed.The Blasting vibration velocity history and stress vibration history at key points and the plastic zone are gained and contrasted with the result of experimental formula;synthesizing the above analysis and considering economical and safety of subsea tunnel,we suggest that charge weight should be reduced and subsea tunnel level should be descended 2 meters.
