  Vent and pumping (if you're a wet mine).    That guys presentation is good.  For pumping - catch water where you can and pump it out - don't be lazy and let it all drain to pump stations at the bottom. Very roughly I work on 0.02kw required to pump 1 l/s one vertical meter.  Size your pipes/dewatering lines correctly to reduce energy wasted to frictional loss.  Also, monitor the power and see what you are using to start with.

  Energy is a very broad term! Please specify a bit which area are you targetting first.

    Ventilation on Demand R2 Las Vegas.pptx

    \major part of enrgy is consumed in the ventilation system of the underground mine. A large surface fan runs at fixed speed and also underground booster fans runs at fixed speed 24/7,

    If we control teh ventilation air undewrground and adjust to ther equiremnts, we can save millions of dollars each and every year, this is Vnetilation on Demand,
