RE: Continuous Miner productioni take it you never worked underground, most mining machines run at 60 % efficiency due to downtime on the outbye end. Also, the machine needs mtc daily at least 6 hours in order to maintain its flame proof charcastertics and permissibility, if not then the chances or risk for explosions will be high. If equipment not maintained daily the safety agency will shut it down. Then you have roof control problems which will slow the mining machine down. The company may be hard fetch to get 350000 tonnes within the next 6 months. MANAGEMENT may give you good news again at the next quarterly meeting, still not making money.
