Similar concentration levels for limestone quarries, as measured in this research, have been observed in other studies as well (e.g. Almeida et al., 2002; Bluvshtein et al., 2011). The background concentration of all particle sizes was achieved within a distance of 209–364 m from the dust source in quarries applying secondary crushing.Rock fragmentation due to blasting depends upon many parameters. The properties of the explosive are one of them. In limestone quarries, ammonium nitrate–fuel oil (ANFO) or site mixed emulsion (SME) are generally used for rock fragmentation. Both these explosives cause substantial changes in the breakage mechanism of rockmass thereby Effect of Type of Explosive and Blast Hole Diameter on

In limestone quarries, groundwater chemistry is mainly dominated by the dissolution of calcite, the major mineral component of limestones, because it is moderately soluble in water [1].The density, permeability and porosity of limestones primarily depend on the degree of consolidation and development of permeable zones Groundwater monitoring of an open-pit limestone quarry:

Temporal Changes of Solid Waste at Limestone Quarries in
This paper is centered on application of Google Images in assessing the temporal changes of solid waste at limestone quarries in and around Yerraguntla.

In 1973, a slope at the Kagemori limestone quarry near the study site collapsed with 300,000–400,000 m 3 of failed rock debris. This accident sparked the start of serious considerations of slope stability problems in theGroundwater monitoring of an open-pit limestone quarry

In addition, small quarry sites were opened and closed as part of larger operations. On Green Head Island several abandoned small quarries were likely worked by the Armstrongs and others. Gesner (1839) reported frequent that mixing (or blending) of limestone is performed from the different part of the quarry or sometime from the outside sources [4–5].

Pierre sighs out deeply, his back hurts, but he has to continue. In the small corridors of the underground quarries at Montrouge south of Paris, he is digging for gypsum and cutting limestone for building material. The quarries are narrow and low, so he has to bend over all the time. Mining gypsum is easier, it’s a softer material.Paris: From quarry to catacombs Tectonics and Structural
