“…64 The quarrying cost, a summation of drilling and blasting cost, was calculated from the operational data reported from a quarry company in Turkey. 65 Since their unit cost was expressed in US$/m 3 , 65 the general density of basalt rock, 3 g/cm 3 , was adopted for the present calculation. Thus, the quarrying cost was estimated to be approximately 1998 US$/ton.…”

This study investigates an advanced synthetic process that produces wear-resistant glass ceramics from mining wastes and smelting byproducts. By mixing gold tailings, red mud, waste limestone, and ferronickel slag at a weight ratio of 25:30:15:30, glass ceramics with chemical compositions and crystalline phases similar to those of fused cast basalt were obtained. The proposed system provided a much higher compressive strength (796 MPa) than fused cast basalt (300–600 MPa); this is attributed to a high ferric-to-ferrous ratio that provides more nucleation sites. Through X-ray diffraction, differential thermal analysis, and scanning electron microscopy analyses, the optimal thermal treatment temperature was determined to be above 1110 K, and the nucleation and formation of distinct crystalline grains were revealed above 1173 K. The crystallization kinetics and activation energy of the glass ceramics fabricated were studied and compared with those of fused cast basalt. The Avrami parameter of the former was determined to be 2.46 ± 0.12, indicating the formation of two- and three-dimensional crystal growths with heterogeneous nucleation. The high crystallization activation energy (381.35 kJ/mol) found implied a high structural bonding. Finally, the cost of the process was compared with that of conventional fused cast basalt, and the environmental impact of the former was evaluated.

“…Blasting has significant environmental, operational, and cost implications, and the outcomes of a blast can impact the entire mining operation, from waste/ore transportation through beneficiation. For instance, an optimized blast fragmentation process improves excavator and dump truck production, minimizes equipment maintenance and repair costs, maximizes crusher throughput, and ultimately, minimizes operating costs [3,8,9]. There are two types of impacts for every blasting event: desirable and undesirable (see Figure 1).…”

Advances in Blast-Induced Impact Prediction—A Review of Machine Learning Applications

Rock fragmentation in mining and construction industries is widely achieved using drilling and blasting technique. The technique remains the most effective and efficient means of breaking down rock mass into smaller pieces. However, apart from its intended purpose of rock breakage, throw, and heave, blasting operations generate adverse impacts, such as ground vibration, airblast, flyrock, fumes, and noise, that have significant operational and environmental implications on mining activities. Consequently, blast impact studies are conducted to determine an optimum blast design that can maximize the desirable impacts and minimize the undesirable ones. To achieve this objective, several blast impact estimation empirical models have been developed. However, despite being the industry benchmark, empirical model results are based on a limited number of factors affecting the outcomes of a blast. As a result, modern-day researchers are employing machine learning (ML) techniques for blast impact prediction. The ML approach can incorporate several factors affecting the outcomes of a blast, and therefore, it is preferred over empirical and other statistical methods. This paper reviews the various blast impacts and their prediction models with a focus on empirical and machine learning methods. The details of the prediction methods for various blast impacts—including their applications, advantages, and limitations—are discussed. The literature reveals that the machine learning methods are better predictors compared to the empirical models. However, we observed that presently these ML models are mainly applied in academic research.

“…Aggregates are constituents that contribute about 80% of the weight and 20% of the cost of structural concrete without additives. They present a great variation in its characteristics, necessitating the study of the technology of the concrete and its quality control both before and during its use in construction (BILIM et al, 2017).…”

The construction industry is responsible for a high consumption of natural resources, demanding high quantities of aggregate materials for use in construction. In addition, large quantities of rubber waste generated worldwide have emphasized the need to find practical reuse applications. The present study partially replaces fine aggregates by ash from a co-processing of milled and burned conveyor belt rubber waste. Test specimens with ash concentrations of 0%, 5%, 10%, 15% and 20%, were made comparing its workability, mechanical axial resistance and absorption of water by capillarity. It was concluded that the partial replacement of sand by 5% of rubber ash has improved the traditional concrete mixture, with better workability, less amount of water, leading to a greater resistance to axial compressive and acceptable absorption of water. Thus, the results confirm that the concrete with incorporation of rubber ash is a potential alternative technology to achieve sustainable development in the construction industry.
