Physical Characteristics of Section Coal and Rock Pillars Under Roof Shock Disturbances From Goaf
Frontiers in Physics, 2020 The stability of a rock strata structure is closely related to its response physical characteristics under external shock disturbance. The roof shock disturbance from goaf is usually one of the important factors that cause coal and rock pillar ...

A framework for quantifying the relationship between intensity and severity of impact of disturbance across types of events and species [PDF]
, 2018 Understanding the impacts of natural disturbances on wildlife populations is a central task for ecologists; in general, the severity of impact of a disturbance (e.g., the resulting degree of population decline) is likely to depend primarily on the ...
