Kinross a model reference in the use of modern dismantling methods

With the vision of an engaged and aware company, on May 12th, in Belo Horizonte, Kinross received the prize from Minérios e Minerales magazine for their project. There was an 81% reduction in the loss of holes from blasting in the Morro do Ouro Mine in Paracatu-MG. The work consisted of mapping, identifying and correcting the main causes for the loss of holes in the process of dismantling. From the mapping, which was based on the best global practices in mining, it was possible to create an operating standard that resulted in the reduction of operating losses, increased operational efficiency, and created greater quality and safety for employees, the environment and community.

According to the mining manager Claudio Freire, the implementation of improvements in the standards of the execution of activities in all areas involved in the mining processes, were essential to ensuring good results. “This award is the result of a joint work aimed at improving the process of dismantling and thus reducing unwanted vibration and any impact to the community,” he stated.

Kinross uses high precision software and advanced technology in its dismantling process to enable the extraction of gold in the city of Paracatu (MG). The use of this technology allows the anticipation of any unusual situations and thereby permits preparation for the best plan for the dismantling with minimal risk to the environment and the community. The company encourages the dismantling processes to be closely monitored by representatives of neighboring districts to the mine, in order for the population to be aware of the actions performed on site, while maintaining direct channels of interaction with the community. Since 2009 until the present, about 227 environmental monitors have been trained to track seismographic controls, noise and dust. During the last three years, between 2011 and 2014, there was a significant reduction of 80% in the number of registered complaints in relation to disassembling. Currently, the vibration level generated by the air pressure is two millimeters per second, well below the maximum of 15 mm which is permitted by law in Brazil. This is according to federal regulations of the Brazilian Association of Technical Standards (ABNT).

In 2013 and 2014, Kinross invested about four million dollars in projects to reduce and control dust. The company operates five monitoring stations placed at strategic locations, which continuously measure the air quality in Paracatu. This monitoring is online and available for public access on the site of the State Environmental Foundation (FEAM): Furthermore, in 2014, biodegradable polymers were applied on 250 acres of internal areas of the mine (equivalent to 250 football fields), which created a surface film that prevents the spread of dust. In 2014, no complaints regarding dust were recorded.

About the Award

On May 12th, in Belo Horizonte (MG) the Minérios & Minerales magazine endorsed the ceremony of the 17th Award for Excellence in Mining-Metallurgical of the Brazilian industry. In 2015, twenty-six projects were honored. The event has the institutional support of Sindiextra, Fiemg, Ibram, the Secretary of Geology, Mining and Mineral Processing of the Ministry of Mines and Energy, DNPM, CPRM, Anepac, Abimaq and the Economic Development Secretary of the state of Minas Gerais.
