  • Continuous Control of an Underground Loader Using Deep

    The reinforcement learning control of an underground loader was investigated in a simulated environment by using a multi-agent deep neural network approach. At the start of each loading cycle, one agent selects the dig position from a depth camera image of a pile of fragmented rock. A second agent is responsible for continuous control of the vehicle, with the goal of filling the bucket at the

    Underground fire incidents differ from fires that take place at the surface. Indeed, when a fire occurs in an underground space, imperfect combustion occurs due to the lack of oxygen, which produces larger amounts of smoke and poisonous gas. Since this occurs in a confined space, there is a limited capacity to remove heat and smoke, and
