Quarries are large wells or depressions in the land resulting from deep extractive activities. When these activities end, most of them are abandoned, representing a potential and/ or permanent threat to the health and physical integrity of the population. Starting from recognizing the complexity of the territory and the multidimensionality of the problem, this article proposes to develop a methodology to assess their danger, taking La Plata County as the case study. The methodology consists of two moments: a first moment of survey and identification of all the quarries present in the case study and a second moment of diagnosis, where a matrix is built to determine the hazard degree. In this way, the study intends to construct an tool for analysis that can be replicated in other regions where extractive activities are carried out, in order to prevent and mitigate their impact.

The absence of specifications for the granulometry a quarry must produce causes a serious problem, making it difficult for quarries to adjust their processes to produce within the range required by clients, and for costumers, making it a difficult process to design asphalt mixes and concretes that conform to the granulometric curves established in regulations. It is essential to develop limit granulometric curves for quarries, adapted to customer requirements. In this paper, a methodology for granulometric control in the quarry is proposed, which includes the collection of process information, the preparation of control charts and the process capability analysis according to the established specifications. Moreover, an example of the development of limit granulometric curves is proposed for the quarry under study located in Argentina, in the province of Buenos Aires, which would allow to produce aggregates whose granulometry can be used in asphalt mixes CAC D19 and concrete pavements.

The city of Arequipa, was honored by UNESCO as Cultural World Heritage in November 2000, in consideration of the buildings that make up the Cercado in its old neighborhoods, defined as Monumental Zone and categorized as: Religious monuments, military monuments, public monuments and domestic monuments. All of them share an element that was already used in buildings constructed by andinas societies before the arrival of the conquerors, the sillar. In this article we will see the main input of the buildings that for over 500 years is continuing to be used, acting as a key element of regional identity, and the proposal to put a value to the quarries of sillar, with a touristic thematic route that has been implemented.

This investigation presents a procedure the most rational method of rock excavations for quarries of construction materials in Cuba. The methods for breaking the ground were studied as well as the parameters that are taken into consideration for the selection. The investigation results provided a tree of excavability of rocky massif. The inputs were point load index and the block size. This procedure facilitates the selection of the most appropriate method, which in turn guarantees mining the quarries satisfactory in compliance with economic and sustainable criteria.
