The method of forming and testing of underground man-made deposits

 

(57) Abstract:

The invention relates to the mining industry and can be used in the processing of deposits by underground methods. The method of forming and testing of underground man-made deposits includes the preparation of underground voids, flow through pipelines in underground cavities tailings and their subsequent development. The difference is that the tailings activate in the pipeline sequentially in gearless infrasonic activator, pneumatic cavitation activator, and the subsequent development of technogenic deposits produced by the method of leach.

The present invention relates to the mining industry and can be used in the processing of deposits by underground methods.

There is a method of formation of technogenic deposits, including the formation of array layers, the formation of anti-filtration screen, laying a perforated pipe, subsequent testing by the method of leach [1]

The disadvantage of this method is the low activity of the leached layer of rock.

The closest analogue for technical things is with the preparation of underground cavities, the feed piping in underground cavities tailings, and their subsequent development to re-use for filling operations [2]

The disadvantage of this method is nedosvechennye useful component of the tailings.

The aim of the invention is to increase the intensity and completeness of extraction of useful component of the tailings during the laying of underground cavities.

This goal is achieved by the fact that in contrast to the known method, including the preparation of underground voids, flow through pipelines in underground cavities tailings, and their subsequent development in the expected manner tailings activate in the pipeline, consistently gearless infrasonic activator, pneumatic cavitation activator pump, and the subsequent development of technogenic deposits produced by the method of leach.

The method consists in the following. Underground cavities are prepared under the bookmark in them tailings. Install insulated jumper, preparing final generation for productive solution. Laid pipelines, which are consequences of the UGA. Using mobile backfill installation tailings are fed into the pipeline together with the leaching solution, where they are activated by a three-stage scheme. Activation tails achieved a deeper revelation of particles of mineral raw materials, the increase in specific surface. After laying in underground space the pregnant solution is pumped to the surface to extract a useful component.

Thus, the present invention in comparison with the prototype allows to increase the completeness of extraction of useful component of the tailings.

The method of forming and testing of underground man-made deposits, including the preparation of underground voids, flow through pipelines in underground cavities tailings, their subsequent development, characterized in that the tailings activate in the pipeline sequentially in gearless infrasonic activator, pneumatic cavitation activator, and the subsequent development of technogenic deposits produced by the method of leach.

SUBSTANCE: method includes use of screw-drilling machine for driving of several first ventilation shafts in ore body and driving several second shafts, while second and each second shaft crosses, at least, one matching first shaft, forming first support walls, supporting ceiling. First supporting ceilings consist of ore body zones between neighboring second shafts, each first support wall has portion of at least one first shaft, passing horizontally through it. Horizontal channels are formed, each of which is placed transversely to matching second shaft between appropriate portions of first shaft, formed in adjacent support walls, for forming of group of continuous ventilation shafts. Second shafts are filled for forming second supporting walls, supporting well ceiling, and first supporting walls are extracted. First ventilation shafts can be made parallel to each other. Second shafts may be directed perpendicularly relatively to first ventilation shafts. In ore body air-outlet and air-inlet ventilation mines can be formed, placed at distance from each other along horizontal line, while first or each first ventilation shaft passes through portion of ore body between air-inlet and air-outlet ventilation mines. Driving of second or each second shaft can be performed by cutting machine, or by drilling or explosive mining.

SUBSTANCE: method includes extraction of mineral resource by underground mine method in liquid environment, under protection of water-resistant rock massif. Full flooding of auxiliary extracting and preparatory mines is performed, which provide for start of wiping operations, with working liquid, neutral relatively to mineral resource and enveloping rocks and being under pressure, matching value of pressure at depth of mine. Process of removal of separated rock beyond underground flooded space is synchronized with replenishment of working liquid volume in this space. Working liquid pressure can be formed by effecting it with force liquid, which is placed either in mine shaft, hydraulically connected to lower flooded auxiliary extracting mine, or in mine shaft and force column, placed on earth surface, above mine shaft, and hydraulically connected thereto. Required height of force liquid column is determined from mathematical expressions. After mineral resource extraction is finished within mine field, flooded extracted space is used for placement of toxic and non-toxic wastes of industries or strategic objects, while process of transfer of wastes or strategic objects into liquid environment is performed synchronously with removal of working liquid beyond flooded space in volume, equal to volume of transferred wastes or strategic objects.

SUBSTANCE: method includes separating resources of all levels on blocks, in form of upwardly elongated hexahedrons. Blocks on adjacent levels are positioned in staggered order with displacement of some of them relatively to others for half of blocks width. Resources of each block within limits of hexahedron are divided on two portions: hexagonal chamber inside the block and block itself of same hexagonal shape on all six sides of chamber. Preparation and cutting of chamber resources is realized by driving field level drifts and mines, intermediate sub-level drifts and mines, and also level and sub-level orts and drifts, driven through mineral resource, from which resources of chambers and blocks are drilled and exploded. Extraction and outlet of mineral resource is performed in three rows - first chamber resources, than inter-chamber blocks under protection of ceiling blocks, after that ceiling blocks deposits. Outlet of resources from chambers and blocks is performed trough ends of level orts and mines, an also through ends of intermediate sub-level mines.

EFFECT: better use of mineral resources, lower laboriousness, lower costs, decreased block preparation time.
