Abstract:

Purpose. To determine dynamic parameters of displacement process above a moving production face in the Nikopol manganese ore deposit

Methodology. Frequency instrumental monitoring has been held at observation stations which had been placed in the main section of semi trough before mining face and after undermining had appeared in the flat bottom of semi trough. Position of points with the maximum values of displacement and deformations of the earth surface relative to the moving face in the main section of trough has been analyzed.

Findings. Field instrumental observations showed that values of maximum vertical displacement of the earth surface considerably exceed the thickness of mined out manganese ore layer. This was caused by water depression influence and physical and mechanical properties of enclosing rock.

Formulas for forecasting of maximal displacements and deformations of earth surface in distinguished points of dynamic semi trough and for calculation of maximum displacement and deformations of the earth surface above moving face has been offered.

Originality. Research of position of distinguished points of dynamic semi trough arising on the earth surface during undermining in the conditions of preliminary water depression has been carried out.

Practical value. Method of determination of position of distinguished points of dynamic semi trough and maximum values of displacements and deformations allows choosing the most effective protection measures during undermining of buildings and constructions.
