Abstract

Determining the possible water inflow is of significant practical interest in designing pits for structures or determining inflows to open mine workings, when the construction of pits or workings is associated with the opening of water-bearing confined strata. Existing methods for determining the filtration inflow in this case, as a rule, are aimed at most accurately establishing its specified value based on hydrogeological characteristics using hydraulic or hydromechanical methods. At the same time, the desire to establish the most accurate value of the filtration inflow is far from always justified for the following reasons. The value of the inflow is primarily of interest either when drawing up a project for the production and organization of excavation work, or when establishing the inflow to mine workings during the development of mineral deposits, when the ultimate goal is to establish drainage methods, the number and performance of the required pumps, energy requirements, etc. Experience in designing construction work shows that the filtration inflow can be established with an accuracy of up to several cubic meters per hour, which provides sufficient opportunity to determine the necessary drainage facilities. Thus, the approximate value of the filtration inflow for the above purposes can be considered acceptable.
