Blasting and blasting-linked software solutions are popular when it comes to winning material in quarries, but drills and large breakers are proving just as attractive alternatives, as Guy Woodford reports.

solve AOp problem in Hulu Langat granite quarry site, Malaysia, three non-linear methods namely empirical, artificial neural network (ANN) and a hybrid model of genetic algorithm (GA)–ANN were developed in this study. To do this, 76 blasting operations were investigated and relevant blasting parameters were measured in the site.

Established in 1947, Colorado Rose Red granite quarry has been owned & operated by the Liesveld for over 68 years. Having origins in Holland as master stone cutters, the Liesveld family migrated to the United States to continue the three-century tradition.

The method of drilling and blasting with explosives is widely used in rock fragmentation applications in underground construction projects, such as tunnels and caverns.

Dave Crosby, an excavation contractor in Santa Fe, N.M., responds: Expansive demolition agents are a good alternative to explosives for quietly and safely breaking boulders into smaller pieces. They're shipped as a …

The obtained results show that the blasting process generates 1.59 kg of CO 2 eq. per metric ton of material, whereas the blast-free quarrying alternative emits 2.05 kg of CO 2 eq./t, in accordance with previous studies (Jullien et al., 2013; Schneider et al., 2018). Hence, it can be stated that, in quarries that have adequate rock mass family ...

The strictness of the result of an excavation, whether mechanical or by means of explosives, is naturally conditioned by its objective and, therefore, by the type of technique applied to achieve it. To attain the best results in terms of rock breakage, and with respect to the final profile, it is important to evaluate the specific excavation energy and its optimization. This study, being a ...

Results from findings revealed a new algorithm for calculating parameters for drawing up the passport of drilling-and-blasting operations during underground mining. Jahed et al. (2015) predicted the blasting environmental impacts in granite quarry in Malaysia. They investigated 166 blasting operations at four granite quarry sites.

Five blasting events in the FYS granite aggregate quarry have been studied, and design parameters have been ob-tained. As an indicator of blast-induced environmental discomfort, vibrations and air blasts are measured using a seismograph. The WipFrag desktop and Kuz-Ram model are used to assess the resulting fragmentations.

2.1 Role of Blast Design in Sustainable Mining and Mineral Processing. Utilizing blasting for rock fragmentation offers distinct cost advantages over employing crushing and grinding methods, which is the reason most mine-to-mill strategies focus on optimizing blast design to produce a desired particle size distribution (Shields and Silva 2022).The primary …

The drill and blast method is used in many quarries to win stone for crushing, but there are alternatives. Patrick Smith reports. European restrictions on blasting operations are now so rigorous that some quarry operators have abandoned the practice in favour of other methods. One of the major reasons for the regulations is that people living or working near, or even in …

This research work assessed the Drilling and Blasting Techniques at the Granite Quarry of AFDIN Construction Company Limited, Katsina State, Nigeria. The objectives were to identify drilling and ...

Significant challenges associated with blasting, such as ground vibration, air blast, and fly rock occurrences, have been incurred at the quarry owing to the adoption of this conventional method. It is thus important to develop an alternative method to the conventional method to prevent further occurrences of the adverse blasting effects.

First published in the March 2015 issue of Quarry Management as Planned Improvement. Cost and productivity optimization through effective blast planning and scheduling. An optimized blast plan developed between one of …

Measuring the blast-induced ground vibration at blasting sites is very important, to plan and avoid adverse effects of blasting in terms of the peak particle velocity (PPV). However, the measurement of PPV often requires time, cost, and logistic commitment, which may not be economical for small-scale mining operations. This has prompted the development of …

limits and all blasts at the quarry must be controlled so that these limits are not exceeded at an offsite residence or other sensitive land use. Precise and detailed record keeping for each individual blast is required. The noise and vibration levels produced when a blast is let off are based on two factors: The technical specifics of the blast,
