The present article describes issues of up-to-date methods and approaches to ensure safety during development of the underground mine in complex engineering-geological and hydrogeological environments. As a priority to ensure safety while constructing mine workings on the karsted territory is the decrease of water content of the rock massif due to construction of spot water intakes above ground. The efficiency of dewatering depends on quantity and capacity of dewatering wells, The same parameters influence on prime cost, so that in the suggested approach the maximum productivity is reached by selecting drilling sites by means of ground geophysics together with study of geological and hydrogeological conditions. In the presented paper, there is an example of successful drainage of karsted layer by constructing water intake consisting of two dewatering wells, which enabled to start developing the ore shoot, which was on suspension due to the complex environment.
