ROCK MASS: - rock as it occurs in-situ, including its structural discontinuities. 377 STABILITY: - the condition of a structure or a mass of material when it is able to support the applied stress for a long time without suffering any significant deformation or movement that is not reversed by the release of stress.

bottom outlets. When capacity – MAR ratios are however, larger than 0.2, not enough excess water is available for flushing and the typical operational model is storage operation. The operating rules for a reservoir need not be inflexible, but can change with

These molds are filled with a workable mortar composed of varying ratios of lime, cement, and standard sand, respectively, such as 116, 219, or 3112. After being allowed to set for 48 hr, they are steamed for 3 hr and the extent of linear expansion is measured.

Prediction of near field overpressure from quarry blasting

2010/12/1In the rest of the blasts, one of the blasting ratios, mainly H/B or T/B in quarry A and B/d in quarry B, is outside the suggested range. The existence of a loose overburden of sandy nature and little cohesion in quarry A is the reason for blasting in higher benches with

In the absence of overburden (or where overburden is relatively thin), the weathered rock may be dug and tipped as waste (effectively overburden). It may be necessary to remove large quantities before acceptable payrock is exposed, and indeed in some tropical zones, there can be as much as a 1:1 ratio between the amount of weathered material and acceptable payrock on any particular site.

Rock mass properties for a mining area are generally determined based on information obtained from the ore - body model (based on exploration data), visual observations in combination with other indices obtained from physical sample testing or geophysical logging. One of these indices is the blastability index. Blastability is generally dependent upon the geological and geomechanical
