Project | Aranzazu

Location | Zacatecas

Project description: In this project we carry out several activities, such as the development of ramps, levels, against fronts, to have access to the mineralized area, with face drilling equipment; We prepare the chambers to the appropriate dimensions for the exploitation stage (overflows, exit shaft) which are drilled with long drilling equipment from level to level, after extraction we proceed to fill the chambers, as well as the ore hauling and tepetate of all activities as mentioned above.

Services: Development and production.

Operations began in area II (Dolores ramp) with the preparation of three of its main ramps with a section of 4.3 meters. X 4 meters In the same way, preparation and infrastructure works were carried out in areas I and III (San Nicolás and Villalpando, respectively), referring mainly to service ramps, crossings, accesses, fronts with a section of 3.0 meters. X 3.0 mts., as well as conventional 1.5 mts. X 1.5 meters. The equipment we used for these developments were: an electrohydraulic jumbo, leg machines, a 6 yd3 scoop tram, two 3 yd3 and 2 2 yd3.

Project | Las Chispas

Location | Hermosillo

Project description: In this project we are dedicated to the development and preparation of tasks, in which sections of Ramps are developed to give access to ore areas, in the same way secondary tasks are given as counterfronts to reach levels of preparation and extraction of the tomb.

Our development program for the year 2021 was 550 linear meters per month, but due to the need to prepare new areas and reach the ore tasks, it was increased to 757 meters per month on average; Currently, ore structures have been cut and the levels of preparation of the tomb have begun, by 2022 it is intended to start production.

On the other hand, the ventilation circuits have been started by means of counterwells made with a leg machine and long drilling equipment, which will help us to have better ventilation for the extension of tasks and their deepening.

Services: Development and preparation.

Project | Mercedes

Location | Sonora

The start of operations in August 2010, a contract for 21,000 meters of worked land for the period 2010 - 2012 began. With electro-hydraulic drilling equipment with one and two arms, with the support of 6 yd front loaders and trucks of 14 m we have produced around 80,000 tons of ore from the start-up period of its new processing plant. We have carried out the reinforcement of the task with a jumbo anchor and the placement of concrete with a robot.

Tunneling drill jumbo machines

Jumbo is the name given to an electro-hydraulic equipment equipped with one or several hydraulic hammers (drills) on hydraulic arms that allow access to any part of the face. It is a machine designed to carry out underground work quickly and automatically: advancement of tunnels and galleries, cross drilling, benching with horizontal holes and mining by cut and fill, among others.
