| 1 | Determination and stability analysis of ultimate open-pit slope under geomechanical uncertainty显示文摘In open-pit mines,pit slope as one of the important parameters affects the mine economy and total minable reserve,and it is also affected by different uncertainties which arising from many sources.One of the most critical sources of uncertainty effects on the pit slope design is rock mass geomechanical properties.By comparing the probability of failure resulted from deterministic procedure and probabilistic one,this paper investigated the effects of aforesaid uncertainties on open-pit slope stability in metal mines.In this way,to reduce the effect of variance,it implemented Latin Hypercube Sampling(LHS)technique.Furthermore,a hypothesis test was exerted to compare the effects on two cases in Middle East.Subsequently,the investigation approved high influence of geomechanical uncertainties on overall pit steepness and stability in both iron and copper mines,though on the first case the effects were just over. | Ali Moradi Afrapoli Morteza Osanloo | 2014 | International Journal of Mining Science and Technology2014，24，1： | 10 |
| 2 | Reserve estimation of an open pit mine under price uncertainty by real option approach显示文摘Reserve estimation is a key to find the correct NPV in a mining project. The most important factor in reserve estimation is the metal price. Metal price fluctuations in recent years were exaggerated, and imposed a high degree of uncertainty to the reserve estimation, and in consequence to the whole mine planning procedure. Real option approach is an efficient method of decision making in the uncertain conditions. This approach has been used for evaluation of defined natural resources projects until now. This study considering the metal price uncertainty used real option approach to prepare a methodology for reserve estimation in open pit mines. This study was done on a copper cylindrical deposit, but the achieved methodology can be adjusted for all kinds of deposits. This methodology was comprehensively described through the examples in such a manner that can be used by the mine planners. | AKBARI Afshin Dehkharghani OSANLOO Morteza SHIRAZI Mohsen Akbarpour | 2009 | Mining Science and Technology2009，19，6： | 8 |

| 7 | Reliability analysis of production schedule in multi-element deposits under grade-tonnage uncertainty with multi-destinations for the run of mine material显示文摘Blending contributes to create an opportunity to achieve the target feed material and helps optimize the run of mine(ROM)material.In addition,it allows mixing different materials and achieving a wide range of quality.Then,multiple destinations can be considered for ROM.The present study seeks to develop a Mixed Integer Programming(MIP)model for the production scheduling of an iron ore mine.Based on this model,different destinations are considered for mine products with different specifications.To this aim,ten scenarios were considered with a number of different destinations.The results indicated that the maximum NPV in the multiple product scenarios is about 15%more than that of the single product scenarios.Further,30 realizations were used to evaluate the effect of grade and tonnage uncertainty.The reliability of the production plan was approximately 61.07%and 62.81%in the first and second period of exploitation,respectively. | Mohsen Jamshidi Morteza Osanloo | 2019 | International Journal of Mining Science and Technology2019，29，3： | 0 |
