STRATAL WATER REMEDIATION IN CASE OF URANIUM IN-SITU LEACHING
Abstract
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 through barren rock was offered and approved. For operational control of stratal water restoration the authors worked out mathematical model, realization of which allows to determined parameters of solutions forced filtration through barren rocks with the aim to have water restoration preset time.

These stations were chosen as locations where the damage risks possibilities available. One of the objectives for selection of these points was to be able to evaluate the affecting degree of th e damage arisen from previous blasting reviewing the past term blasting records such as blast pattern, type and amount of used explosives, shot location etc. by determining the level of the frequency and velocity of the vibration.
