Abstract. In the article, solutions are presented for the placement of rock salt from the excavation of mine workings during the construction of a mine in a salt dump and salt waste of the processing plant of the Dekhkanabad potash fertilizer plant in the tailing dump. The technology of anti-seepage protection of the salt dump and the brine collector was recommended, which allows to reduce the negative impact on the environment and groundwater. The recommended anti-filtration protection of the base of the salt plate includes a device 1) of a Bentomat screen, a protective layer of loams, an attachment layer, and 2) above the screen drain of geocomposite material TenCatePolyfelt DC 602E.
To ensure rational use of land and safe exploitation of salt wells, landslide formation issues were considered. Mathematical descriptions of the trajectory of movement of the center of mass of a landslide, its parameters and speed of movement are described.
In order to prevent landslides, experiments were carried out on salt traps to secure their surface with sodium silicate solutions. Based on the results of laboratory experiments and experimental-industrial tests, it was established that density and calcium module of the fixing solution, as well as porosity and filtration coefficient of the fixed salt waste affect the gelling time, the penetration rate of the solution and the fastening strength of the salt waste.
Based on the results of the theoretical, laboratory and pilot-industrial studies of the process of fixing salt waste, a method, recipe, project and plan of measures for checking the quality of work and safety measures for the implementation of the chemical method for fixing salt waste from the Tyubegatan potash deposit were developed.
The fixing solution is proposed to be applied by spraying. The flow rate of the fixing solution for fixing 1 m3 of sand is justified and the speed is established, its injection scheme is: four point-pair, diagonal-sequential.
Keywords: salt dump, tailings storage, anti-filtration protection technology, reduce the negative impact on the environment and groundwater, the process of fixing salt waste, formulation, chemical method.
