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...

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...
