The following ratios can be used as first approximations in designing blasts Bear in mind that the ratios will usually have to be adjusted as one learns more about how the particular rock reacts when blasted Burden = roughly 24 to 36 times the explosive diameter Using AN/FO at a specific gravity of g/cc i light rock g/cc density = 28 x diameter ii medium rock …
The efficient extraction of patterns that have good relative risk and/or odds ratio has not been previously studied in the data mining context In this paper we investigate such patterns We show that this pattern space can be systematically stratified into plateaus of convex spaces based on their support levels Exploiting convexity we formulate a number of sound and complete …
