This article considers the modern status of conditions of construction of drainage systems and prospect direction of improvement of method and technical means of dehumidifying of mineral deposits. There are shown the most significant disadvantages in construction of drainage systems. As a rule, nowadays, construction is carried out from the levels, which systems stay two-or three-circuit. Barrage system includes installation of dewatering wells, constructed from the surface. Excavation and growth of mining depth leads to changing of this technology by dehumidifying, using systems of uprising drain holes, backfilled from underground excavations. In connection with discrete placing of water-decreasing and uprising drain wells, there are saved the conditions for formation of groundwater skip into protected open pit. In these conditions, for the purpose of minimization of water inflows, there are applied the horizontal drainage systems, which came from the benches of open pit edge. Most of these modern drain systems are constructed from three levels: from the surface, from underground excavations and from benches of open pit edges. The foregoing makes this task extremely complex, because each considered level requires application of special technologies and technical means. Solving of ecological problems is complex. Development of VIOGEM Institute radically changes the drain system construction conditions, offering the structure of combined drain unit and construction of single-circuit drain system from one level (from benches of open pit edge). New drain unit is constructive unification of horizontal and uprising drain system. Source

This article describes the deep mines drainage technology, based on the drilling of upward drain holes from underground mine workings. This technology, developed in «VIOGEM» JSC, is widely applied during the open-cast, combined open-cast-underground and underground mining of deep-seated ore deposits in Russia and other countries. Offered method of drainage is characterized by the range of advantages and makes it possible to simplify the drain systems cardinally, particularly by the following measures: -carrying out of drain operation on one level; -refusion of application of well sinking pumps, which will increase the reliability of drain system; -decreasing of level of electric energy consumption; -limiting of application of dewatering and shallow wells; -increasing of technical and economic efficiency of drain measures; -exclusion of passing of contaminations into water-bearing horizons and initial drain waters. Positive results of industrial testing and cumulated experience became the basis for the following measures: wide spreading of drainage systems by upward drain holes instead of drilling; equipping of dewatering deep wells with complex construction, as well as their long-term, constant and complex exploitation.

The article is devoted to a topical trend in the theory and practice of mining-research, development and manufacture of automated geoinformation systems GIS for geological and surveying support of mining. The authors described the core GIS GEOMIX designed by VIOGEM with the active participation of geotechnical services of mines in Stary Oskol iron ore region of KMA; its evolutionary and resupplied structure; basic and special functional modules, their purpose and tasks; ways of further improvement. The emphasis is laid on integrated automation of information support in mines inside a unified software environment and the unicity of computer technologies embodied in GEOMIX for modeling rock mass disintegration in open pit mines by drilling-And-blasting; estimation of fragmentation quality and distribution of quality indexes in broken ore; modeling of jointing and block structure of rock mass and potential failure wedges in benches with calculation of bench stability; automated design of open pit mine elements; virtual monitoring of ore drawing from panels in underground mines; advanced design of open pit mines with optimized transportation and ultimate limits. It is informed on the application of GEOMIX in optimization of raw material reserves and future development at mining-And-processing integrated works in Stary Oskol iron ore region: feasibility study of quality standards for produced minerals and raw materials (ferruginous quartzite, high-grade iron ore; nonmetals in overburden rocks); justification of expediency of discarding unmarketable reserves of prevailing minerals stored in special areas; validation of profitability of open pit mining at Lebedinsky and Stoilo-Lebedinsky deposit down to a depth that is lower than the current project depth limit by 250 m within the set mining lease boundary on the ground surface; development of the technology for advanced open pit mine planning with alternative designs of extraction and transportation charts and with selection of the best alternative; trial of the technology at Stoilensky Mining-And-Processing Integrated Works.

Safety and efficiency of mining are in many ways governed by quality of geological surveying that is only achievable to date with the multifunction geoinformation systems. High efficiency GIS represent integrated software packages composed of different modules interlinked through the common interface, which generates a local computer network intended to maintain a technological system of automated production units. Developed by VIOGEM, GIS GEOMIX is meant for open pit and underground hard mineral mining; it allows geological modeling and handling of various specific tasks, including mineral reserves appraisal (geological and commercial reserves), estimation of amount of stripping, automation of geological surveying, mine planning, drilling-and-blasting pattern design, prediction of blasted rock quality, etc. Complete package of GIS GEOMIX includes the following functional modules: basic-DrillProj for geology, Mark for surveying, DrillBlast for drilling and blasting operations and DrillMine for mine planning; special modules-GeoStructure for geological structure, BlastModel for predicting disintegration of broken rock in open pit mines, StoneFrame for estimation of block structure of slopes and broken rock fragmentation, FlowFrame for ore drawing control in underground mines. Automation of information support based on GIS GEOMIX creates conditions for on-line analysis of geological situation in an open pit (underground) mine and for prompt decision-making on optimal engineering designs and targets for annual production scheduling and long-term mine planning, improvement of blasting quality in open pit mines and stabilization of ore quality fed to crushing and processing in underground mines, optimization of mineral loss and efficient monitoring of ultimate pit limit slope stability.
