Mines operating close to communities face growing challenges, especially with their drilling and
blasting activities. Proper management of environmental and community impacts is critical to provide
sustainability to the mining business in the long-term, by enabling the licensee to operate. This paper
will present new technology solutions to minimise the impacts to communities and the environment
from blasting operations. A case study of the wireless initiation projects conducted at Kinross Morro
do Ouro Mine (located in Paracatu, Minas Gerais – Brazil), will be presented.
Focused on overcoming the complex challenges in the mine, Orica and Kinross searched for
initiatives to optimise the drilling and blasting operations. The team evaluated the WebGen™
wireless initiation system for controlling environmental impacts as well as operational flexibility and
productivity. Since January 2023, three planned wireless blasts to demonstrate the technology and
applications were executed. In the tests, the vibration level was able to be maintained lower than the
limit of 3.0 mm/s while dust and flyrock impacts were well controlled.
The main benefits of using this technology for the Morro do Ouro Mine are: reducing the number of
blasts while increasing the blasted mass per month; control of projection of fragments using
additional cover; dust control by watering the bench easily; lightning initiation risk reduction due to
the absence of wires or tubes on the surface; flexibility in changing the blast day to better control the
noise and dust; flexibility in mine planning mining (potential application in the future).
The use of the WebGen™ wireless initiation system, enables improved productivity while enhancing
safety and reducing impacts to communities. Implementation of this technology has enabled Kinross
Morro do Ouro Mine to build trust with its neighbours, maintain the license to operate, and helping
to mobilise resources in a sustainable way. This has allowed Kinross to position Morro do Ouro Mine
as a world reference operation, especially in relation to innovation, safety, and social responsibility.
