This paper aims to review and assess quarrying impacts comprehensively, besides, trying to crystallize a futuristic vision of urban landscape post-quarries.
The increasing number of abortive and abandoned quarry pits, and the several associated geo-environmental hazards have given cause for greater concern. Environmentalists, governments, and the general public now seek innovative ideas, and research collaborations that will reduce incidents of abortive and abandoned quarry pits.
closest residential area is about 400 m away from the quarry. The quarry produces about 4.1 million tonnes of limestone annually for the construction industry in Malaysia. The quarry is geologically within Kinta Valley which has been dated Devonian to Permian timeline [14]. The limestone includes numerous relatively thin argillaceous beds,
1. Introduction. Human cognition is important and indispensable in the exploration of and interaction with urban spatial environments. People have built many 3D urban models over time, from physical models of the 1933 "Plastico di Roma Imperiale" model and the 1964 "New York Panorama" model (Marshall Citation 2018) to recent …
Quarrying activities and rock extraction generally cause several environmental effects on the surrounding areas. The alteration of landscape due to activities like excavation, …
The specific objectives were to (1) assess the visual impact of quarries and CDW dumpsites at the landscape level and (2) investigate the effect of land conversion …
The investigation yielded that among the five quarry sites, the social and environmental effects of the gravel and sand quarrying operations which the respondents strongly agree with their mean ...

The article deals with the evaluation of the visual impact arising from quarrying, mining and civil engineering works that involve extensive surface excavation. An indirect method has been formerly proposed to quantify the level of visual impact (Lvi) based on the two physical variables that define the magnitude of change in a natural …
Eight case studies of surface excavation discussed in previous studies were selected to validate the revised Lvi method (Dentoni et al. 2006, 2015; Dentoni and Massacci 2007, …
The direction of the quarry in this model was considered 270 degrees, and the spacing of vertical cuts in the quarry face was assumed to be constant and is considered 2 m according to traditional ...
Footnote 2 The extraction took place through the use of simple tools which divided the bench into steps perpendicular to the fracture line and parallel to the cava front, Footnote 3 and generally determined spaces characterized by a pit morphology with walls of about 30–40 m high, leaving in place vertical walls that make the quarry acquire a ...
part of stone quarry/quarry roads/waste dump yard in 2016, is termed as "destroyed/degraded agricultural land" in this study. Sample satellite images of a cutting unit, water recovery ponds at the cutting units, waste dumps and agriculture land are shown in Fig. 3 which were used for the visual identification.

An indirect method has been formerly proposed to quantify the level of visual impact (Lvi) based on the two physical variables that define the magnitude of change in a ...
The new index to measure cumulative visual impact, SCVLI, indicated that Thasos island would have to be 3.4 times larger in 1984 than its actual size to accommodate a visibility of exactly 1 pixel of quarry perimeter visible in each pixel of the whole island, and 8.5 times larger than its actual size in 2000 to attain a uniform visibility load ...
Granite quarrying for many years has served as an important source of construction materials supply, employment and revenue especially in developing countries like Nigeria which are endowed with ...

The principal airborne hazards in the mining industry include several types of particulates, naturally occurring gases, engine exhaust and some chemical vapours; the principal physical hazards are noise, segmental vibration, heat, changes in barometric pressure and ionizing radiation. These occur in varying combinations depending on the …
Visual distortions can affect your ability to see normally. Often called visual disturbances, they can cause changes in eyesight such as blurry or wavy vision. These distortions can have varying causes. For example, wavy lines may be due to a problem with the retina, while an autoimmune condition or simple astigmatism may cause blurry vision.
The visual and aesthetic aspects of any object are defined by its colour, form, line and texture. To these, might be added compositional reference elements such as scale and, in the case of three ...
Sofia Boutella leads a band of insurgents taking a stand to protect a farming community from the evil empire in the grunge action auteur's Netflix sci-fi movie.
Among these effects, the shape, extent, or chromatic contrast of the mining surface with the original land form may represent a huge loss of appeal for the growth of new urban settlements. To eliminate, or if not possible, at least to reduce these effects, two different approaches may be developed. ... visual impact assessment, quarry ...
A visual impact assessment is prepared when an expansion of existing quarries is proposed. The use of geographic information systems based, visualization techniques historically has been used to ...
visual impact assessment of a limestone quarry in "Moitas Negras", Portugal. Materials and methods Visual impact assessment is often regarded as a subjective process.
Hence, it portends danger for those living around the place. Nartey et al. (2012) compared the health status of the respondents before and after the inception of the quarrying activities, and ...
The visual impact of the quarries extends over larger areas as noticeable scars of high colour contrast, reducing the aesthetic appeal of the landscape and deteriorating the scenic quality of...

effects of blasting quarry operations on the environment and its inhabitants shed light on the gas lighting strategy employed by the aggregate industry and their explosives engineers to alter the public's perception of reality by consistently and repeatedly claiming that blasting within regulatory limits cannot cause structural ...
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 …
