It is expected that blasting will use the same practices and controls as employed by OGNZL for the Martha Pit. It is expected that blasting will be undertaken using electronic detonators, emulsion bulk explosive and small charge weights. Maximum explosive quantities per blast hole are expected to vary depending on operational requirements. Standard practices will be followed with respect to controlling potential effects, including fly rock and will be included in a Vibration Management Plan. 2.2.3 Mobile mining equipment OGNZL estimates of mobile mining equipment required over the life of the GOP as summarised in Table 2-1 Table 2-1.
