Estimate of Stress-Strain State of Rocks in the Area of Drilling Kola Ultradeep Well

The values of horizontal tectonic stresses are estimated up to depth of 11 500 m by the measurement of velocities of longitudinal and transverse waves in rock samples extracted from various depths when drilling Kola Ultradeep Well.     

Statistical Criteria and Estimation Results for Regularities of Gas-Dynamic Phenomenon Distribution in Potash Deposits

An analysis and estimate are performed for possible schemes of spatial distribution of gas-dynamic phenomena in potash deposits by the methods of mathematical statistics. The problem stated is solved by comparing the numerical characteristics of the events observed and those obtained on the basis of the theoretical model developed.

Design considerations for mine workings under accumulations of water

The study outlines the effects of surface and underground subsidence patterns on the spatial distribution of in-situ permeability and its effects on groundwater inflow. The behaviour of strata surrounding a longwall face where limited knowledge exists has been outlined. The effects of mining subsidence on the surface flow pattern have been described with the remedial solutions. The mechanism of formation of sinkholes in certain chemical rockmass has been described. Factors affecting mine water inflow have been described in detail with the aid of a simplified conceptual model and case studies. Practical examples of undersea workings and those under a large accumulation of water are given, both in the United Kingdom and worldwide.
