An Accurate Digital Subsidence Model for Deformation Detection of Coal Mining Areas Using a UAV-Based LiDAR
Autor: Junliang Zheng, Wanqiang Yao, Xiaohu Lin, Bolin Ma, Lingxiao Bai
Publikováno v: Remote Sensing, Vol 14, Iss 2, p 421 (2022)
Coal mine surface subsidence detection determines the damage degree of coal mining, which is of great importance for the mitigation of hazards and property loss. Therefore, it is very important to detect deformation during coal mining. Currently, the

Monitoring surface subsidence in the Binchang mining area using small baseline subset differential interferometric synthetic aperture radar with Sentinel-1A data
Autor: Cui Bai, Chuqiang Zhang, Wanqiang Yao, Junliang Zheng, Yun Shi, Yang Xiang, Yuancheng Huang, Beibei Zhao
Publikováno v: Journal of Applied Remote Sensing. 14
Surface subsidence caused by mining is difficult to monitor. Traditional field measurements are time-consuming and labor intensive. Small baseline subset (SBAS) technique is a long-term sequence method based on the principles of radar interferometry

Cu-catalyzed oxidation of indoles to isatins
Autor: Junfei Luo, Yanchao Zhao, Xing Xu, Junliang Zheng, Hongze Liang
Publikováno v: Tetrahedron Letters. 58:4591-4594
The first example of Cu-catalyzed oxidation of indoles to isatin derivatives by the use of cheap aqueous tert-butyl peroxide as an oxidant was developed. This methodology is practically convenient and highly functional group tolerant, allowing a vari
