The sustainable development of coal mines by new cutting roof technology

Yang Tai, Bin Yu, Rui Gao, Qiangling Yao, Zhao Li & Hongchun Xia
China consumes more than 3.6 billion tons of coal every year, accounting for over 60% of the energy consumption. Therefore, the sustainable development of coal mine is a problem needed to be solved by the Chinese government. During the coal resources recovery, the protective coal pillars between the adjacent working faces cause the serious loss for coal resources. In order to solve the problem, it was put forward that the new technology of roof cutting...

The Influence Law of Eccentric Load on the Performance of Yielding Bolt

Yang Tai, Hongchun Xia, Shaopin Huang, Jie Meng & Wei Li
In order to adapt high stress and large deformation of roadways, the prestressed yielding bolt has been developed. However, borehole deviation makes the boreholes out of perpendicular to the roadway surface, and the prestressed yielding bolt will be under eccentric load. In order to reveal the influence laws of eccentric load on the performance of the prestressed yielding bolt, the numerical simulation was carried out in this paper. Then, the influence of eccentric load on...

Data from: Measuring researchers’ potential scholarly impact with structural variations: four types of researchers in information science (1979–2018)

Xiucai Yang, Jianhua Hou & Chaomei Chen
We propose a method to measure the potential scholarly impact of researchers based on network structural variations they introduced to the underlying author co-citation network of their field. We applied the method to the information science field based on 91,978 papers published between 1979 and 2018 from the Web of Science. We divided the entire period into eight consecutive intervals and measured structural variation change rates (DM) of individual authors in corresponding author co-citation networks....
