Assessment of influence of hydrostripping on draining efficiency of open cast blocks under complex hydrogeological conditions

There the study object is the deposit at the basin of Kursk Magnetic Anomaly. There the study purpose is to estimate the influence of hydraulic mining process on the open cast dewatering and on the hydraulic spoil bank dewatering for the rise of hydrostripping efficiency and of drainage efficiency and for the keeping of supplies in the underground waters. The theory of filtration consolidation, the method of electric hydrodynamic analysis have been used. The dependences have been ascertained, and the influence of residual heads of indurground waters in the zones of working edges near the contour on the hydrostripping efficiency and on the drainage efficiency has been determined; the assessment technique of draining effect of filtering elements in the nuclear zones of hydraulic spoil banks has been worked out. The members of drainage system and the sizes of working sites providing the accumulation of service waters have been ascertained; the process schemes for the advanced alluvion of thin-dispersed watertight rocks on the plots of filtering basis of hydraulic spoil banks have been worked out. The sizes of working sites and the schemes of one-contour drainage have been introduced at the Yuzhno-Lebedinski open cast.
