Currently, in the open pit mine of the Gabriela Mistral and Ministro Hales Divisions the mitigation of particulate matter pollution on roads consists of irrigation by water trucks on a discretionary basis, i.e., the operator decides when to activate the irrigation of roads while he’s driving. For this operation, different procedures are considered depending on whether flat areas or slopes are watered, in order to avoid generating traction problems that could lead to safety incidents, mainly in mining trucks. One of the aspects that could be improved in the current process is that irrigation does not always achieve optimum wetting, as it is often more watered than necessary, generating water losses, operational problems and unsafe conditions.
The proposed technological solution must consider the following requirements:
Identify technological solutions to implement an intelligent irrigation system for the mine pit roads, mitigating environmental pollution and optimizing the use of water and the fleet of water trucks.
The following will not be considered in the background evaluation process:
Irrigation of the roads in the mine pit is done by water trucks on a discretionary basis and often does not achieve optimal wetting to adequately mitigate environmental pollution in the area.
On a permanent basis.
Irrigation of roads using water trucks based on a previously prioritized schedule or on demand according to the estimated level of pollution, visualization and experience of mining truck operators, who requests irrigation in certain areas (radio communication).
New technologies have not been tested.
