The deposit of Lomonosov developed at a trial level, now is at a stage of transition to its fullscale development by the open way. At the same time, first of all, a single open pit is expected to fulfill the diamond pipes of the southern group – Arkhangelskaya and Karpinsky 1 and 2. In this connection the development directed on a substantiation of systems of drainage «big career» and water removals of drainage and other waters were required also. Authors, on the basis of the analysis and generalization of available data, have tried to find the optimal engineering decisions allowing essentially to raise ecological safety of work of given systems at rather low technical and economic expenses.
The main hydrogeological problems in the development of diamond deposits in Yakutia are related to the need to utilize large volumes of drainage brines from the quarry and waste saline water from the beneficiation plant. The technology for burying these solutions in the permafrost strata is proposed. The results of field experiments are discussed and the processes accompanying the distribution of saline water in the permafrost zone are analyzed.
The analysis of dewatering system operation during transition to underground development of the Mir kimberlite pipe is given. Numerical geofiltration model of the field area is developed, which is used to compare different scenarios of dewatering system operation. Forecasts of brine inflows to the drainage system and changes in levels in the Meteoro-Ichersky aquifer complex for the period up to 2020 are given. Recommendations on drainage system optimization taking into account drainage brines burial are developed.
Проблема охраны подземных вод от загрязнения в соледобывающих районах страны с каждым годом становится все более актуальной, что обусловлено постоянным ростом объемов минерализованных промышленных стоков, поступающих в водоносные горизонты из технических водоемов (шамохранилищ, рассолосборников и т.п.) ...
Широкие исследования по проблеме охраны подземных вод в горнодобывающих районах, развернувшиеся в последние годы, к сожалению, часто слабо учитывают специфические аспекты этой проблемы, обусловленные технологией горного производства. Между тем специфика такого рода подчас существенно влияет на гидродинамический и гидрохимический режим подземных вод района ...
