Blast-induced ground vibration is one of the most significant challenges in explosive rock fragmentation, affecting mine stability and worker and machine safety. However, limited research has suggested a correlation between slope stability and blast-induced ground vibration. Thus, improving mining sustainability requires assessing mine …

Abstract. Mining and quarrying for minor minerals impart significant economic, environmental and social impacts in and around the affected areas. The problem is severe in the small river catchments as …
The study adopted purposive sampling; a survey of 134 respondents representing 80 quarry workers, 40 quarry owners, 10 EIA Experts, 3 NEMA staff and 1 County geologist were sampled purposively. Weighted and the Consolidated Scores were entered on Microsoft Excel for cleaning and later transferred to Statistical Package for Social Sciences (SPSS ...
Quarry blasts and seismicity. Blast operation creates both elastic and inelastic deformation within the nearby rock mass. A seismic event is a rapid inelastic deformation that occurred within a specified volume of rock (Ma et al. 2015).Regulatory authorities usually monitor blasts in quarries on the scheduled date of the operations by …
Also, the fracturing modelling by specific software programs is crucial to improve the block size assessment and the increase the quarry yield. In this research …
Quarry, place where dimension stone or aggregate (sand, gravel, crushed rock) is mined. The products of dimension stone quarries are prismatic blocks of rock such as marble, granite, limestone, sandstone, and slate. …
To install an R package on Quarry from your account, first download the file from an R project repository using the wget command, and then install it using R CMD INSTALL -l.. Suppose you want to get a package for multivariate normal and t distributions mvtnorm.The following example creates a new directory bin and stores the package file …
Our exploratory analysis of new quarry sites uses community-center site locations coupled with a site suitability analysis (a Linear Scale Transformation of …
Abstract. Any productive or technological activity takes place in a social context and is embedded in a history of native practices, perceptions, and use of multiple landscapes. This paper explores topics that supplement and build upon technological and cultural historical approaches to quarry research. Briefly considered are: quarries as ...
Available research studies showed the dominant potential of dolomite quarry waste as cement and aggregate replacement. In the current article, a large number of research papers have been reviewed. The finding of the different studies showed that using the dolomite waste as cement and aggregate up to certain extent increases the …
Archaeologists have struggled to find meaningful and cost effective ways to analyze and interpret prehistoric quarry sites. Quarry site deposits typically contain …
During the research, quarry landscape attractiveness level was defined, showing that its main motif is that of quarries' uniqueness, differentiation, as well as interest and curiosity evoked. Quarry areas have elements provoking many stimuli, thus affecting all of the senses (sight, smell, hearing, and touch). Moreover, the study results ...
An Old Kingdom basalt quarry at Widan el-Faras and the quarry road to Lake Moeris in the Faiyum. Presentation at the 45 th annual meeting of the American Research Center in Egypt, Toronto, ON; abstract in 'Program and Abstracts', p. 39-40.
Though Ludvigson and his colleagues sought grant support to pursue their Stikes Quarry research, their "frontier science" ideas were initially met with resistance during peer review. "Scientists are trained to be skeptical. They want proof of concept," Ludvigson said. "This is a common problem for scientists who venture beyond the ...
My quarry research involved the study of Ordnance Survey maps, geological maps and local street maps of the area. Other clues have been obtained from nineteenth century field trip accounts, articles in geological journals, contemporary newspapers and more recent descriptions of the fossils found in these quarries. Archives at the East …

IU students, faculty, and staff can request accounts on Karst, IU's newest high-throughput computing cluster; for instructions, see ARCHIVED: Requesting an account.User data on Quarry has not be …
Usually, quarry lithics exhibit evidence for early-stage reduction: large flakes with a lot of weathering rind on them—this cortex must be removed in order to evaluate the suitability of the stone for knapping, and to reduce the initial size of cobbles for transport elsewhere for further reduction. ...
