A system for employing gravity to provide electrical power for mining operations in a mine includes a battery configured to power an electric vehicle. The vehicle includes a kinetic energy capture system that can charge the battery as the vehicle conveys a loaded vehicle down a ramp from an ore face to a chamber. Traveling down the ramp produces a surplus charge in the battery due to a weight differential between a loaded vehicle traveling down a ramp producing more energy via the kinetic energy capture system than energy used by the vehicle to convey the empty vehicle up the ramp to the ore face. A discharging device disposed in the chamber is configured to discharge the surplus energy out of the battery and into the mine's power grid. One or multiple trips between the ore face and the chamber may fully charge the battery.

1. A system for employing gravity to provide electrical power for mining operations in a mine, wherein the mine has a shaft extending downward from the earth's surface to a chamber containing a power grid for powering the mining operations, and a deposit having an ore face positioned between the chamber and the earth's surface, such that the chamber is disposed downwardly from the ore face, the system comprising: a ramp extending between the ore face and the chamber;a zero-emissions vehicle including a kinetic energy capture system;a first battery on the zero-emissions vehicle, wherein the first battery is configured to power the zero-emissions vehicle and to be charged by the kinetic energy capture system when the zero-emissions vehicle travels down the ramp from the ore face to the chamber while the zero-emissions vehicle carries a load;a discharging device disposed in the chamber, wherein the discharging device is configured to discharge energy out of the first battery and into the power grid only when the first battery is attached to the discharging device in the chamber. 2. The system of claim 1, wherein the first battery is configured to receive a net surplus energy charge from the kinetic energy capture system when the zero-emissions vehicle makes a trip cycle, wherein a trip cycle is a loaded trip down the ramp to the chamber and an unloaded trip up the ramp back to the deposit. 3. The system of claim 2, wherein the first battery is attached to the discharging device after at least one trip cycle. 4. The system of claim 2, wherein the first battery is attached to the discharging device after more than two trip cycles. 5.
