Open Pit Mine Semi-continuous Mining Process Reasonable Length Of Haul Truck And Process Cost Study

Semi-continuous process for open pit mining with improved production efficiency and economic benefits,etc.,this thesis for open pit truck semi-continuous process system,reasonable transportation distance and cost of the process,the use of function fitting,gray relational analysis,theoretical analysis Methods Opencast semi-continuous process system truck economical transportation distance,trucking economies of scale were studied and related links.Thesis final curve according to fuel consumption,tire and determine a reasonable transport distance of haul trucks,trucking costs in the calculation of the coefficient of variation in oil prices introduced by studying the composition of the first open pit costs,economies of scale for trucking specific analysis,K,to study the changes in oil prices,the impact on the economy and reasonable transportation distance truck produced to obtain reasonable transportation distance of its economic trends.By analyzing the factors affecting the material haul semi-continuous process,the establishment of model materials transportation distance.In open pit cost analysis is based on a semi-continuous process system construction and application of the boundary conditions were systematically analyzed.Finally,the paper introduced Heidaigou surface as an example of theoretical verification,determine the economy of the open pit mine 830E and 930E haul trucks reasonable,and semi-continuous processes for its mining and stripping semi-continuous process carried out a detailed analysis.The results showed that:a semi-continuous process system construction conditions at the design production capacity of semi-continuous process for Dai single bucket-haul truck intermittent process boundary conditions;the application conditions in the case of already existing system,the system earnings,boot border scale production run or repealed.Our research semi-continuous process for enriching the theory and construction of large and efficient low carbon Opencast important.
