Justification of integrated monitoring system for geological environment of potassium salt deposit

A project system of integrated monitoring is developed for rock mass in the course of mining of a high-mountain potassium salt deposit with extremely difficult and specific geological conditions. The present-day exploitation of commercial-value seams is complicated by water ingress exposed during heading operations in an extraction panel within the test mine field. From the results of processing and comprehensive analysis of geological and geophysical data accumulated in additional appraisal of the area, the structural features of the productive and overlying strata are determined, the potentially hazardous sites are identified, and their impact on the mining safety is estimated. The positions and sizes of sites with complications revealed in the geological section by the integrated study of geophysical data are taken into account in geomechanical evaluation of risks of the impermeable strata discontinuity. The accomplished research and the comprehensive data analysis made it possible to develop recommendations on mining technologies on promising sites of the test mine field. The integrated monitoring system of geological environment control aimed at reduction of adverse environmental impact and at enhancement of mining safety includes a network of base observation lines for the impermeable strata areas of different discontinuity risks, and provides two systems of observation modes.
