The relationship between lowering the Earth's surface and bearing pressure above the advancing longwall face

This work aims to develop a method for determining the increase in stresses above an advancing longwall face of Western Donbas mines. The paper presents a solution to the problem. It is based on the analysis of geodetic instrumental observations of the earth's surface lowering and rock mass deformation above the advancing longwall face. Length and propagation in the roof and floor of the extracted seam are the main geometrical parameters of the zone of high rock pressure. Currently, the quantitative parameters of this zone are not considered.

Effective methods of approximation and prognostication of settling engineering buildings

Aim. Improvements of the methods of approximation of settling by exponential, finely-rational, polynomial, and sinusoidal functions with the definition of intervals between observation cycles. Methods and results of the work. The methods of approximation and prognostication of settling of control benchmarks of building are examined.
