Uranium mineral base of the Republic of Kazakhstan is one of those leading in the world and its development perspectives are huge. Computer-aided projecting system of uranium in-situ leaching mine is based on optimized mathematical models under several criteria. For operational and constant control of all uranium ISL technological subsystems condition it was worked out computerized system flowchart consisting of four hierarchical levels, each of which is responsible for control task applicable to those levels. Com...

One of fundamental dependence for estimation of metals ISL process effectiveness is working solution productivity function of block operation time. As a rule, that dependence is set by test at pilot site before the whole deposit exploitation. Other way to set that dependence consists of uranium ISL, kinetics known differential equations solving, which still does not give reliable results. The report offers experimental analytical method of that task - solution based just on one experimental dependence – uranium ...

Under the effective legislation of the Republic of Kazakhstan, Stratal underground waters after uranium mining from stratum-infiltration deposits subject to rehabilitation to initial state. In this connection, the 13- years test with respective monitoring of aquifer on Irkol deposit has been done. Observations have proved that ore-bearing aquifer area of about 20000 square meters is almost rehabilitated to its initial hydro-chemical state. To intensify strata waters restoration, method of forced solution drawing t...
