Blasting at the Glasshouse Quarry by C. Roberts et al 1 describes an investigation carried out to determine whether quarry blasting from Excel Quarry Pty Ltd is having a current impact on the stability of the Mount Coonowrin rock faces. This paper describes further studies undertaken using modelling techniques from blast
Few studies of blasting exist because of difficulties in obtaining reliable fragmentation data or even obtaining consistent blasting results. Many researchers have attempted to predict blast fragmentation using the Kuz-Ram model, an empirical fragmentation model suggested by
Jul 28, 2016 The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity. The availability of sand at low cost as a fine aggregate in

Feb 07, 2017 A new site-specific vibration prediction equation was developed based on site measurement performed in a sandstone quarry. Also, several vibration prediction equations were compiled from the blasting literature and used to predict ground vibration for the studied quarry. By this way, site-specific equation created by regression analysis and the equations obtained

Jun 01, 2013 Ground vibrations induced by blasting in the cement quarries are one of the fundamental problems in the quarrying industry and may cause severe damage to the nearby utilities and pipelines. Therefore, a vibration control study plays an important role in the minimization of environmental effects of blasting in quarries.
resulting from regular dewatering of the quarry pit. Blasting may cause problems with groundwater quality. (Vincent et al. reported that shock waves from blasting operations loosened clay particles from solution cavities causing muddying of the ground water. However, Ukpong 17 investigated the impact

layer will be compromised, and flyrock may occur if blast holes are overloaded. The size of the mast and drill steels carried by the rig are important considerations in drilling efficiency. If a quarry plans to use 30-foot bench heights with 7 feet of sub-drill, a drill rig
Aug 01, 2009 There are two rules of thumb in literature 1. An eight millisecond (8ms) firing window for consecutively initiating charges to minimise blast vibration. 2. Construction blasts produce high blast frequency and large mine blasts produce low frequency. The widely accepted introduction of electronic blasting systems in the Australian quarry and ...

Mar 19, 2020 The selection of appropriate blasting vibration limits for civil construction projects and quarry operations has a major influence on a project?s overall cost, duration, and environmental impact. In some cases, the application of an overly conservative limit may affect a project?s financial viability to a point where it may not even commence, despite passing all the
