The extraction of aggregates is one of the activities that generates the greatest impact on the environment. Currently, the province of Santiago de Cuba has 8 reservoirs where resources are exploited for the production of materials for construction. The areas degraded by the exploitation of aggregates in the province occupy around 200 ha, which causes a great impact on the environment. For this reason, it was proposed as Objective: to carry out an environmental impact assessment of the exploitation of the Yarayabo quarry, in order to propose the preventive and corrective measures that must be adopted to minimize the impact on the environment, in order to make the exploitation and preservation of the natural environment. In the methodology: scientific methods were applied that allowed the analysis of the factors that influence the alteration of the environment resulting from mining exploitation. Reaching as result: the environmental impact matrix of the quarry object of study. And in conclusion: measures were proposed for each of the components impacted to mitigate their effects and thus achieve responsible mining. [ABSTRACT FROM AUTHOR]

One way to guarantee the food security of the eastern part of the country and to fight against climate change, is undoubtedly the construction of the underground tunnel in the municipality of Mayarí, due to the urgency of transferring the water from where it exists to the areas that they are scarce of this resource, which makes it a prioritized task, however, it is necessary to evaluate the impacts caused by such construction, taking into account the importance of the effects that already produce the country's environmental policy. The objective of this research is to identify, characterize and evaluate the environmental impacts resulting from the construction of the underground tunnel in the municipality of Mayarí and propose measures to minimize and correct the negative effects. As part of the work, a plan of measures for the prevention, mitigation and correction of negative effects was develo [ABSTRACT FROM AUTHOR]

The execution and operation of the underground protective works, like any constructive mining work, is not exempt from generating impacts on the environment where it is located. However, the need to build it does not necessarily imply the indiscriminate degradation of the environment, because through the established procedures of Environmental Impact Assessment and environmental management the negative impacts identified can be minimized. For this reason, it was proposed as Objective in this work: to identify, characterize and evaluate the environmental impact resulting from the construction of protective works in the municipality of Moa, with the purpose of proposing preventive and corrective measures to make compatible the construction and the preservation of the environment natural. In the methodology: scientific methods were applied that allowed the analysis of the factors that influence the alteration of the environment resulting from the construction of the work. Reached as a result: the environmental impact matrix of the work under study and in conclusion: measures were proposed for each of the components impacted to mitigate and correct their effects.
