In underground mining, mineral transport is a fundamental activity to guarantee the supply of material from the pits to the concentrator plant. Mineral transport is carried out horizontally (conveyor, scoop), vertically (hoisting system and conveyor belts) or by ramps and inclines (truck, dumper). Mineral transport system of a mine comprises the combination of these types of transport, each one of them having certain characteristics that are taken into account for their choice. Among the influencing factors for choosing the type of transport are the cost, transfer time, performance and versatility to cover the different haulage routes. Vertical transport system is one of the best alternatives for mines whose ore bodies are deeper due to its lower cost and transfer time, and increased productivity. The present research was carried out considering El Porvenir mine property of Nexa Resources as the unit of analysis. This is located in the district of San Francisco de Yarusyacán, province of Cerro de Pasco, in the department of Pasco. El Porvenir mine has a shaft whose depth is 1,280 m and is divided into 4 compartments: two for mineral hosting, one for transportation of people and one for installing services with a ladder for emergencies and inspections. The purpose of this professional sufficiency work is to analyze the vertical transport mineral to increase the productivity of the electric hoist in underground mines, for which information was collected on the operation of the electric hoist, recording the events raised shift by shift. With the information collected, the Pareto analysis was performed to determine the problems with greater frequency (80-20 methodology). Once the problems were identified, the root causes were determined by applying the 5 whys methodology. Subsequently, the root causes were placed in an effort-impact matrix to group them and determine the degree of priority for subsequent execution of the proposed solutions. Finally, using the Power BI software, a statistical analysis of the influence of work shifts, weekdays and hours per day was made to determine if there was any type of relationship with daily production.
