Monitoring observations of gravity field allow to reveal the dynamics of deformation processes of rock masses and to carry out the forecast of dangerous and catastrophic situations. Based on the results of repeated observations, a dynamic gravity anomaly is calculated, defined as the difference between the subsequent and previous values of gravity. Since all the invariant components of the gravitational field are equally present in any pair of observations, the dynamic anomaly reflects only a specific mining or fast flowing geological process. The main noise-producing factors during gravimetric monitoring are considered, methods for interpreting dynamic anomalies are suggested, examples of gravimetric studies at emergency sections of mines are given.
