[QUOTE="Metamorphic, post: 147460, member: 3682"] Makes sense that drives on other levels are not directly above or below each other, as its the reef 'dip' that regulates the drives bearing over distance berween levels. Yes? More questions my friend. (1) we have completed removing the ore from the stope between levels and we fill the stope with waste from the level above as you state. Are we doing this because its more economical than raising the waste to the surface? Or is it mainly to enhance structual integrity for further stoping from lower drive levels? Does the waste used for filling this void come from cutting the drive to the reef? (2) We know the reef runs (lets say) in a North/South direction and the dip is 55 degrees from strike. Where is the best spot to sink the shaft? Do we sink 'inline' with reef direction cutting through the reef and then driving in at different levels after we pass it to pick it up again or is there a better way knowing we want to avoid as much overburden as possible? Is it best to sink where the loam test results show the most color in pan directly above the deposit Even though the reef does not outcrop? Hope these questions make sense mate. Thanks in advance.
