Hydrogeological calculations methodology for drainage of Safonovskoye deposit

Abstract

When designing and implementing the dewatering of mineral deposits it is necessary to take into account and use the experience of already conducted dewatering on similar or close to them deposits. One of such objects, interesting in hydrogeological respect, for which the known experience of dewatering has already been accumulated, is Safonovskoye deposit of brown coal and refractory clays in Smolensk region. Exploration and study of its hydrogeological conditions began in the post-war years and continued until 1950. Some additional works were carried out later - up to 1962. On the basis of exploration works more than 8 mines were designed. The construction of the first mines started in 1949. The mines were successively put into operation: 1 - in 1953, 2 - in 1954, 3 and 4 - in 1956, 8 - in 1957, 6 - in 1958, 7 - in 1959. At the end of 1959 the construction of mine 5 was completed, which is currently intended only for the extraction of refractory clay.
