A system for detecting a potential collision between an object and a mining machine, the system comprising: a sensor, a first strobe light and a second strobe light, and an electronic processor configured to identify a virtual perimeter around at least a portion of the mining machine, identify a plurality of collision zones, the plurality of collision zones including at least one immediate collision zone and at least one potential collision zone, receive a signal from a sensor indicating detection of the object in one of the plurality of collision zones, determine, based on the signal, whether the object is in the immediate collision zone or the potential collision zone, generate, in response to determining that the object is in the potential collision zone, a first indication, and generate, in response to determining that the object is in the immediate collision zone, a second indication different than the first indication.
