Study on deformation law of roadway surrounding rock under dynamic disturbance

Meikuang Anquan
The surrounding rock is in a state of high stress during deep mining of coal mine, and the dynamic disturbance may lead to the instability of the surrounding rock and even rock burst.

Remote Sensing Assessment of Forest Disturbance across Complex Mountainous Terrain: The Pattern and Severity of Impacts of Tropical Cyclone Yasi on Australian Rainforests

Remote Sensing, 2014
Topography affects the patterns of forest disturbance produced by tropical cyclones. It determines the degree of exposure of a surface and can alter wind characteristics.

Characterization of the gas explosion under continuous disturbance by coal gangue in a coal mine gob

Case Studies in Thermal Engineering
Gas explosions in coal mine gobs caused by the spontaneous combustion of coal usually result in serious threat to energy security. The main feature is that the explosion flame is initially disturbed by the coal gangue. To recognize the characteristics of

Practical gigahertz quantum key distribution robust against channel disturbance

, 2018
Quantum key distribution (QKD) provides an attractive solution for secure communication. However, channel disturbance severely limits its application when a QKD system is transfered from the laboratory to the field.
