"Mining Rock Mechanics in China"

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 find the appropriate countermeasures. They can be classified in three types: monitoring of landslide, rockburst control, and use of innovative mining technology. The presentation will firstly introduce a study on the theory of double-blocks mechanics including the measurement of the Newton force, which is the necessary and sufficient conditions for initiating a landslide disaster due to the block motion, using the so-called constant-resistance and large-deformation cable with negative Poisson’s ratio effect. Secondly, the experiment on rockburst and its control will be introduced. As an important method for rockburst control, the use of a novel energy-absorbing bolt which features with a constant-resistance under impact loading and large-elongation for containing large deformations of the country rock mass at burst-prone conditions. Finally, a new longwall mining method the so-called the 110 mining method (1 working face, 1 excavation roadway and no pillar), including directional pre-splitting cutting will be introduced. Compare with the traditional longwall mining method the so-called as 121 mining method (1 working face, 2 excavation roadways and 1 remaining pillar), using the new 110 mining method, 50% of the roadways are no longer needed to be excavated; instead, they are formed by a controlled roof collapse. By reducing the need for roadway excavation, mining accidents and consequently costs can be significantly decreased.

Prof. Manchao He is currently an Academician in Chinese Academy of Sciences, Professor at China University of Mining and Technology, Beijing (CUMTB). He is also the Director of State Key Laboratory for Geomechanics and Deep Underground Engineering in Beijing, China. He is recognized as the leader of the Chinese Union for Mining Innovation (CUMI). And he served as the Vice President of International Society for Rock Mechanics (ISRM), Chairman of ISRM Education Fund Committee.

He received his Bachelor and Master Degree in engineering geology from Changchun College of Geology in 1981 and 1985 respectively, and obtained his Ph.D. in Engineering Mechanics from CUMTB in 1989. He got an Honorary Doctorate from University of Mons in Belgium in 2012. He mainly engaged in the research of Rock Mechanics and Engineering, including mining technologies, rockburst mechanism, landslide, active fault stability analysis, monitoring and control, etc. He has published 10 books and over 190 papers in technical journals and in conference proceedings. He also serves on the Editorial Board of several Journals, and received 5 National Prizes and awards in his career.
