Análisis técnico del libre aprovechamiento para obra pública denominado "Proaño", ubicado en el cantón Morona, provincia de Morona Santiago

Abstract

This thesis aimed to carry out a technical analysis of free use for public works in the civil parish of Proaño, Morona canton, Morona Santiago province, resolving the need to regularly provide material for road works in the northern sector of the canton, for second order roads. Therefore, it has been worked based on the following approaches: qualitative research, which will be based on a consolidated bibliography, including web pages, essays, theses, scientific journals, books, physical and digital pre-existing information of the area; in addition to a quantitative approach through which data were collected during field work: topographic survey, sampling and finally the interpretation of mentioned data with specialized software (Civil 3D and AutoCAD). It was possible to determine the mining exploitation plan which consists of the uncovering of the vegetation cover layer, extraction of relevant material by mechanical removal through an excavator. It involves two stages with three benches of 11 meters high, a 16-meters exploitation platform, a slope inclination angle of 45 degrees, for subsequent loading and transportation, with a daily production of 216 m3. Once the exploitation stage is completed, the mine will be closed permanently in correspondence with the accesses and roads within the mining concession, slopes stabilization, water management by surface runoff will be done by means of coronation ditches which will guide water to the nearest tributary avoiding the accumulation of it on the slopes, thus affecting its stability.
