| 1 | Fuzzy TOPSIS method to primary crusher selection for Golegohar Iron Mine(Iran)显示文摘Selection of the crusher required a great deal of design regarding to the mine planning. Selection of suitable primary crusher from all of available primary crushers is a multi-criterion decision making(MCDM) problem. The present work explores the use of technique for order performance by similarity to ideal solution(TOPSIS) with fuzzy set theory to select best primary crusher for Golegohar Iron Mine in Iran. Gyratory, double toggle jaw, single toggle jaw, high speed roll crusher, low speed sizer, impact crusher, hammer mill and feeder breaker crushers have been considered as alternatives. Also, the capacity, feed size, product size, rock compressive strength, abrasion index and application of primary crusher for mobile plants were considered as criteria for solution of this MCDM problem. To determine the order of the alternatives, closeness coefficient is defined by calculating the distances to the fuzzy positive ideal solution(FPIS) and fuzzy negative ideal solution(FNIS). Results of our work based on fuzzy TOPSIS method show that the gyratory is the best primary crusher for the studied mine. | Mohammad Javad Rahimdel Mohammad Karamoozian | 2014 | Journal of Central South University2014，21，11： | 5 |

| 3 | Prediction of rotary drilling penetration rate in iron ore oxides using rock engineering system显示文摘Prediction of the drilling penetration rate is one of the important parameters in mining operations. This parameter has a direct impact on the mine planning and cost of mining operations. Generally, effective parameters on the penetration rate is divided into two classes: rock mass properties and specifications of the machine. The chemical components of intact rock have a direct effect in determining rock mechanical properties. Theses parameters usually have not been investigated in any research on the rock drillability. In this study, physical and mechanical properties of iron ore were studied based on the amount of magnetite percent. According to the results of the tests, the effective parameters on the penetration rate of the rotary drilling machines were divided into three classes: specifications of the machines, rock mass properties and chemical component of intact rock. Then, the rock drillability was studied using rock engineering systems. The results showed that feed, rotation, rock mass index and iron oxide percent have important effect on penetration rate. Then a quadratic equation with 0.896 determination coefficient has been obtained. Also, the results showed that chemical components can be described as new parameters in rotary drill penetration rate. | Hossein Inanloo Arabi Shad Farhang Sereshki Mohammad Ataei Mohammad Karamoozian | 2018 | International Journal of Mining Science and Technology2018，28，3： | 1 |
| 4 | Investigation of different coal types effect on the overall plant recovery显示文摘Coal washing plants are usually fed from various sources. Coals include different combinations which should be considered for increasing the plant proficiency. Thus different methods have been used to enrich various coal types. In this study, Alborz-Sharghi coal washing plant was investigated which is fed from five coalmines. The optimum recovery was achieved for all coal types individually through experimental design. The controllable operation parameters in the experiments were collector dosage,frother dosage, solid percent content and particle size. The other parameters such as impeller speed,pH, conditioning time and flotation time were kept constant for all experiments. The optimum combination of coals was also specified. The results show that the optimum recovery for coal blends is 91.2%which shows much improvement relative to the plant conditions. | Ghasemi J. Karamoozian M.

| 5 | 磁铁矿含量对邦德功指数和预处理的影响:以Chadormalu铁矿为例(英文)显示文摘研磨是机械回采和采矿中成本最高的工序。确定破碎特征和预处理对提高研磨效率非常重要。氧化铁的抗震、力学和破碎性能是研究铁矿石爆破和破碎过程中岩石碎块的重要参数。本文研究了Chadormalu铁矿中氧化物矿石(磁铁矿和赤铁矿)的抗震和岩土力学性能。结果表明:磁铁矿含量与单向压缩强度,拉伸强度,P和S波速率呈正相关关系,而与泊松比和孔隙率呈负相关关系。为研究铁矿石的破碎和预处理性能,对含有不同磁铁矿含量的样品进行导索爆破实验。结果表明,高磁铁矿含量的样品爆破碎片数较多。研究了矿区430次爆破的邦德功和磁铁矿含量。结果表明,随着磁铁矿含量增加至50%,爆破范围减小,邦德功和能量消耗也降低。此外,通过研究多次具有相同爆破参数和相似地质条件的爆破,研究石碓碎片和磁铁矿含量的关系。结果与前述磁铁矿与预处理的关系一致。 | Hossein INANLOO ARABI SHAD F SERESHKI M ATAEI M KARAMOOZIAN | 2018 | Journal of Central South University2018，25，4： | 0 |

| 7 | Effect of ultrasonic irradiation on particle size,reagents consumption,and feed ash content in coal flotation显示文摘Ultrasonic waves have a lot of use in the particle surface cleaning.As flotation is one of the methods associated with surface properties,this paper investigates the effect of these waves on performance,particle size,reagents,and feed ash content in coal flotation.To accomplish this goal,coal samples in three size fractions,including coarse(-800 to+400μm),medium(-400 to+100 μm)and fine(-100μm)with various feed ash content.The flotation experiments were evaluated by process indexes such as yield,combustible recovery,and selectivity index.The results indicated the increasing of yield.The increasing was significant in medium size.Furthermore,the results showed that in presence of ultrasonic waves,the collector and frother consumption decreased.And also,applying ultrasonic waves would result more combustible recovery and selectivity index.The ash selectivity index had the highest impact for high feed ash content. | Hossein Ebrahimi Mohammad Karamoozian | 2020 | International Journal of Coal Science & Technology2020，7，4： | 0 |
