in this study, analysis of actual data collected from sugar beet hybrid monogerm seed producers in the 2001 growing season and laboratory seed samples showed that delay in steckling sowing resulted in the reduction of raw and pure sugar beet seed yield and the increase of undersize seed portion. non-significant effect of sowing dates on unkernel seed percent showed that the high temperatures wi...

explosion has always been regarded as one of the most complicated engineering problems. as a result, many engineers have preferred rather simplified empirical approaches in comparison to extremely complex deterministic analyses. in this paper, however, a numerical simulation based on the combined finite/discrete element methodology is presented for analyzing the dynamic behavior of fracturing r...

Drilling and blasting play a very important role in driving the economy of opencast mines, as various mining activities related to strata handling are dependent on size rock mass created due blasting. Thus analysis fragments from explosion is essential order monitor its compatibility with deployed machineries/HEMMs (such shovel, dumper, dragline, etc.). As over fragmentation well under both ten...

Pliant abrasive media is transforming the way coating maintenance personnel approach offshore surface preparation. Pliant media users are often able to lower total job costs and provide higher quality surface preparation. 29(59,(:#2)#2))6+25(#0$,17(1$1&( Millions of dollars are being allocated toward the maintenance of offshore platforms with the goal to maximize oil production operations. A mo...

Abstract Increasing the mining depth at Praid Saline and implicitly state of stresses strains determines an increase in dimensions resistance structures (pillars ceilings). Furthermore, seismic effect generated by detonation explosives contributes to degradation structures. In order reduce destructive drilling-blasting technology a proposal is made for implementation mechanized salt cutting whi...

This article aiming at the lack of research on influence rock clamp production cutting blasting under high in-situ stress conditions and damage criteria for RHT constitution in numerical simulation. Combined with critical criterion embedded function constitution, determining constitutive was studied, mechanical parameters Metamorphic sodium lava were substituted to obtain threshold The smooth p...
