| 2 | A critical review on the developments of rock support systems in high stress ground conditions显示文摘Extreme ground behaviour in high-stress rock masses such as rockburst prone and squeezing ground conditions are encountered in a range of underground projects both in civil and mining applications.The occurrence of such ground behaviour types are difficult to predict and special design and construction measures must be taken to control them.Determining the most appropriate support system in such grounds is one of the major challenges for ground control engineers because there are many contributing factors to be considered,such as the rock mass parameters,the stress condition,the type and performance of the support systems,the condition of major geological structures and the size and geometry of the underground excavation.The main characteristics and support requirements of rockburst-prone and squeezing ground conditions are herein critically reviewed and characteristics of support functions are discussed.Different types of energy-absorbing rockbolts and other support elements applicable for ground support in burst-prone and squeezing grounds are introduced.Important differences in the choice and economics of ground support strategies in high-stress ground conditions between civil tunnels and mining excavations are discussed.Ground support benchmarking data and mitigation measures for mines and civil tunnels in burst-prone,squeezing and heavily swelling grounds conditions are briefly presented by some examples in practice. | Masoud Ghorbani Korosh Shahriar Mostafa Sharifzadeh Reza Masoudi | 2020 | International Journal of Mining Science and Technology2020,30,5: | 8 |
| 3 | Reinforcement selection for deep and high-stress tunnels at preliminary design stages using ground demand and support capacity approach显示文摘Underground mining is going to be deeper gradually because near surface resources are going to be depleted. Therefore, risk of seismic events in underground mines is escalating. Additionally, existence of the large ratio of horizontal to vertical stress, could be a potential reason for high-stress condition and occurrence of dynamic activities. Depending on various parameters such as the level of induced stress, rock properties, etc., ground demand changes and it is difficult to estimate. On the other hand,under seismic condition, energy dissipation and deformation capacity of supports is the most important factors, however, rock support performance factors in dynamic conditions are still under investigation.Expanding the knowledge of reinforcement behaviour and capacity, specifically that of the rockbolt as a primary element in seismic conditions, would help to develop a suitable, safe and economic support design. This paper contains various methods to estimate ground demand including the intact rock properties approach, failure thickness and ejection velocity estimation, and rockburst damage potential method. It also covers measurement methods of rockbolts energy dissipation capacities such as drop test,blasting simulating, back calculation and momentum transfer measurement methods. A large-scale dynamic test rig is also explained. Based on the findings, a table and a graph to show the applicable range of each type of rockbolts were presented. Suitable rockbolt types for various ground energy demand and deformation capacity range were categorised in the table and the graph. The presented support selection method facilitates the selection of a suitable reinforcement system at the preliminary stages of design and guides the designer to adjust the support reinforcement system based on observed ground and support reaction. | Reza Masoudi Mostafa Sharifzadeh | 2018 | International Journal of Mining Science and Technology2018,28,4: | 5 |

| 6 | Mineralogical Evidence for Regional Metamorphism Overprinted by Contact Metamorphism显示文摘The Soursat metamorphic complex(SMC) in northwestern Iran is part of the Sanandaj-Sirjan metamorphic belt.The complex is composed of different metamorphic and plutonic rocks,but is dominated by metapelites composed of garnet,staurolite,kyanite,fibrolite,cordierite,and andalusite.Porphyroblasts in schists have the same fabric,and three stages of schistosity are present.The internal schistosity(Sn) inclusion trails are also offset by conjugate sets of extensional schistosity(Sn+1) and a second(Sn+2) that crenulates(Sn+1).Polyphase metamorphisms are present in the complex.Garnet,staurolite,kyanite,and fibrolite assemblage preserves conditions during the M1 metamorphic event.This assemblage yields a P-t estimate of 645±11°C and 6.5±0.5 kbar.Other samples of the central part of SMC contain cordierite and andalusite(M2) overgrowth that yields a P-t estimate of 532±33°C and 2.1±1.1 kbar. | Mahboobeh JAMSHIDI BADR Fariborz MASOUDI Alan S.COLLINS Ali SORBI | 2012 | Acta Geologica Sinica(English Edition)2012,86,1: | 3 |

| 8 | Partially decoupling and collar bonding of the encapsulated rebar rockbolts to improve their performance in seismic prone deep underground excavations显示文摘Rockbolt is widely employed all over the world as an effective ground reinforcement element in order to secure the underground workplaces.Ordinary encapsulated rebar or rebar rockbolt is most popular and commonly used as reinforcement in a ground support system because of its accessibility,cost effectiveness and easy practicability.Reinforcement elements in a seismic condition such as rock burst have to dissipate the energy release of the dynamic impact via their deformation and ultimate load capacity,knowing that the former is more important.In other words,achieving early stiff behaviour along with large deformation capacity in rockbolts are the goals for new development in rock reinforcement.Yielding rockbolts are expensive while some of them have large deformation capability with low ultimate load capacity.In this paper,modifications were made on encapsulation of rebar rockbolts to utilise it effectively as a yielding reinforcement in seismic conditions.Applying a sufficient decoupled length in the shank of rebar rockbolts which industry has regularly been using to control the bulking of the stress fractured ground,improves the deformation capacity of the bolt.Additionally,leaving a collar bonding underneath of the bearing pad and plate removes the weaknesses of the head anchorage of rockbolt.Therefore the dynamic performance of the bolt is improved by these easily applicable modifications.The behaviour and performance of encapsulated rockbolts have been discussed first,then the effects of modifications are illustrated.The proposed modification of the rebars is not only cost effective but also easy to apply in the field and improves the performance of reinforcements in seismic prone zones. | Reza Masoudi Mostafa Sharifzadeh Masoud Ghorbani | 2019 | International Journal of Mining Science and Technology2019,29,3: | 2 |

| 10 | Effect of milling atmosphere on structural and magnetic properties of Ni-Zn ferrite nanocrystalline显示文摘Powder mixtures of Zn, Ni O, and Fe2O3 are mechanically alloyed by high energy ball milling to produce Ni–Zn ferrite with a nominal composition of Ni0.36Zn0.64Fe2O4. The effects of milling atmospheres(argon, air, and oxygen),milling time(from 0 to 30 h) and heat treatment are studied. The products are characterized using x-ray diffractometry,field emission scanning electron microscopy equipped with energy-dispersive x-ray spectroscopy, and transmitted electron microscopy. The results indicate that the desired ferrite is not produced during the milling in the samples milled under either air or oxygen atmospheres. In those samples milled under argon, however, Zn/Ni O/Fe2O3 reacts with a solid-state diffusion mode to produce Ni–Zn ferrite nanocrystalline in a size of 8 nm after 30-h-milling. The average crystallite sizes decrease to 9 nm and 10 nm in 30-h-milling samples under air and oxygen atmospheres, respectively. Annealing the 30-h-milling samples at 600°C for 2 h leads to the formation of a single phase of Ni–Zn ferrite, an increase of crystallite size, and a reduction of internal lattice strain. Finally, the effects of the milling atmosphere and heating temperature on the magnetic properties of the 30-h-milling samples are investigated. | Abdollah Hajalilou Mansor Hashim Reza Ebrahimi-Kahrizsangi Mohamad Taghi Masoudi | 2015 | Chinese Physics B2015,24,4: | 2 |
