TECHNOLOGY FOR THE DEVELOPMENT OF BREEDS, PREVIOUSLY WASHED TO THE HYDRO-HANDLE NO.2 OF THE CUTTING OF "CHERNIGOVETS" JSC, USING A HYDROMONITOR AND A SUCTION DREDGER
Refinement of coal reserves at a number of Kuzbass coal mines requires re-laying of rocks that have previously been washed up in the hydraulic dumps located above the coal reserves. Based on the analysis of changes in the physicomechanical properties of alluvial rock in the hydrohole, a complex technology of re-laying of the waterfalls is proposed, which made it possible to substantiate a new way of developing and moving them. The essence of this method of re-laying rocks of hydraulic dumps lies in the fact that the safety and efficiency of mining operations is ensured not only through the use of a complex of hydromechanized technologies, each of which uses technical means that most closely match the physical and mechanical properties of rocks in different developed areas of the hydraulic mine dump, but also sequence of their application and combination. The application of efficient and safe technology in the conditions of development of rocks of the hydraulic dump No. 2 of the “Chernigovets” mine and their transfer to a new place of laying - in the hydraulic mine “Internal No. 3” is substantiated. The total number of rocks in the hydro dump No. 2 and the volumes of rocks developed by different equipment complexes have been established. The schedule of works and the list of the main equipment are determined. The costs for the acquisition of the main equipment of the hydrocomplex, for the mining and construction works and the specific operating costs for the development of rocks have been determined.
