..., so as to carry out the rock burst disaster warning. Based on the strength-stress ratio method, the possibility of rockburst in the deep-buried tunnel of Pingliang-Mianyang National Expressway is predicted in this paper. At the same time, the FLAC3D numerical simulation software was used to build...

... Abstract Common features within manifestation of strong rockbursts with fault-slip mechanism and induced earthquakes that are studied in this paper are: correlations between the direction of the major fault wall displacement caused by geodynamic events and the regional stress field; typical...

... Abstract Rockburst is characterised by the wide occurrence areas and the long delayed time at a pumped storage power station in Heilongjiang province of China. For the study, a new method is proposed to identify the induced rockburst based on the combination of microseismic (MS...

... Abstract Rockburst is a sudden disaster that occurs during the underground excavation. It is still challenging to predict the rockburst quantitatively. In the underground excavation, the complex geological structures, the mechanical properties of rock mass, the shape of the excavation...

... Abstract Rockburst is a common dynamic disaster in underground engineering under high ground stress. A large number of rockburst examples show that there is a strong correlation between the instability failure of slab cracking surrounding rock and rockburst during the excavation process...

... Abstract Time series prediction of parameters is a method of learning existing observational data and predicting its future evolution, which has been applied in many fields. In this paper, the key microseismic indexes are mined to describe the rockburst development, and a hybrid prediction...

... Abstract With the increasing of mining activities in China, a series of hazards such as landslides, rockbursts, large deformations occur frequently. At present, the challenges for these hazards consist in finding appropriate countermeasures. They can be classified in three types: monitoring...

... Abstract Mine development and operation in North and South America as well as Australia and Asia manage rockbursting conditions as a routine but always complex and difficult challenge. The hazard and the associated risks can be managed based on local experience, monitoring, informed data rich...

... Abstract This paper intends to learn more about the mechanism and failure feature of rock burst disaster in coal mines from the micro-cracks propagation characteristics in the fragments of rockburst tests in laboratory, the relationship between the micro crack propagation type of rock...

... geological incidents such as high rock temperature, heavy water ingress and rockburst. In this paper we focus on the relationship between TBM operational parameters obtained from the instrumentation on the TBM and the geological conditions encountered, with particular emphasis on rockburst phenomenon...

... ABSTRACT Rockburst is a spontaneous, violent fracture of rock that can occur in deep mines. The research of rockburst has for many years and not yet for satisfactory answers. Based on the data of rockburst cases, and take to mining depth, ratio of the maximum tangential stress of surrounding...
