Method of mudflow geotechnological development of minefields

FIELD: mining.

SUBSTANCE: solid mass is subject to alluvial re-deposition with water flow. For that purpose, above the level of minefield section there created is water reserve, and in the minefield section there opened is some part of reserves with pioneer ditch. Drain ditch is passed from minefield section so that vortex and laminar flow zones are created in it. Water is drained from storage pond. Water flow breaks solid mass starting from pioneer ditch area, weighs the solid mass material and moves in the flow via drain ditch to the zone with laminar current conditions. In that area the productive particles are deposited, and thin clay material in the form of pulp flows to sludge pit.

EFFECT: reducing labour input and losses of useful components.

The invention relates to the field of mining, can also be used for re-development of man-made objects and for production of construction materials.

Known natural geological processes leading to the formation of placer deposits (Smirnov V.I. Geology of minerals. M.: Nedra, 4th ed., Peres. supplementary, 1982, 669 S., S. 452-483), including the destruction of the native array and alluvial redeposition of material water flows.

The lack of natural geological processes involved in the formation of deposits, is the lack of control of processes.

Closer analogue to the technical essence is a technological solution based on flushing and transfer of the material of the array of water flows. Examples of such technology are arpii (Sobolevsky V.I. Wonderful minerals. M: Education, 1983, 192 S.).

The disadvantages of these solutions are the complexity of the control processes resedimentation material array and high technology metal loss.

The aim of the invention is to reduce the complexity and loss of useful components.

This objective is achieved in that the storage tank water to the ore pass rossopomodoro the ditch on the sides which are warehoused loose and ku is a similar material. Rukovodstva ditch is used for directional water supply from its accumulation to the array field. In the same section of the field, from rukovodstvo ditches, construct a pioneer pit. He seeks to expose the initial plane of the rocks array, which will begin its destruction thread. From the end of the plot there are the river bed diversion ditch, and on the sides in the initial part of creating a barrier framing dams, forming the collection of flow in a single direction. On the surface section of the field there is no possibility of control over the traffic flow, so the river bed diversion ditches erect the barrier dam, through which collect multidirectional flows in the channel of the river bed diversion ditches. In the final part of the river bed river bed diversion ditches form controlon with barrier dam. Controlon at the end of the river bed diversion ditches and barrage dam designed to permanently stop the flow. Collectively controlon and barrage dam provide a complete stop of the flow and prevent the destruction of the surface outside the mining lease. Then, water is supplied from the storage tank by rukovodstvo ditch and add to the sides loose and lumpy material into the stream. Additional material can increase the density of the moving medium in the flow of the La increase the kinetic energy of the flow, destroying the array. Reaching the pit at the mine, the thread destroys the material of the array field, captures, weighing it in water and moves through the river bed diversion ditch. Multidirectional flows from the captured material from the array field is directed into the bed of a river bed diversion ditches barrage dam, located on the perimeter of the site deposits from river bed diversion ditches. As the material flow is divided particles in hydraulic grain size and the formation of zones of concentration. The transfer material water flow serves as a basis for the creation of alluvial placer deposits. After completion of the flow generated concentration zones develop on alluvial technology.

Before the water supply, the array is subjected to explosive loosening. Loose material water flow destroys more productive than dense, so the pre-opening material of the array can be redeposited more efficiently.

The explosive shattering of rocks takes place during the passage of the water flow on the site. The explosion of the material of the array is weighed and the water flow with less captures and moves a significantly larger amount. In addition, the explosive loosening gives the ability to control the volume of resedimentation.

On the social site river bed diversion ditches provide and maintain turbulent flow regime, and the final section provide and maintain the laminar nature of the flow. Turbulent flow regime at the initial part of the river bed diversion ditches provides confidence to move all of the material without deposition. This thread can be created by placing obstacles in the channel of the ditch. On the plot with laminar flow occurs stratification of the flow density of its components. This mode provides the deposition of bulk material and particles with a relatively high density. Plot with laminar flow serves as an area for the accumulation of productive material.

Explosive loosening and mudflow movement of the array carried out in stages, starting with the remote part of the site in relation to the place of accumulation of water. The gradual destruction and displacement of the material of the array is carried out at a large initial Deposit when the accumulated volume of water sufficient to resedimentation of the entire material of the array, or when significant source of disunity areas of the field. In this case, start the destruction and displacement of material from the remote in the direction of flow areas. Each subsequent section is prepared private lesson, starting with the pioneering of the pit.

Rossopomodoro the ditch being constructed so that when the flow direction is expanding and due to p is smava boards loose and lumpy material, Abraxas with boards, falls into the stream. The flow of water through the bed rukovodstvo ditches accompanied by the erosion of the coasts, the collapse of which provides an introduction to the stream of bulk material, accumulated in advance.

In the final part of the river bed diversion ditches form a place of deposition for particles with different hydraulic sizes, which comprises three part extend, create a flat slope of the bottom region across the width and served in the thread at the beginning of this zone, additional water. The expansion of the bed part to reduce the height of the flow, thereby reducing the flow rate and transfer in the laminar regime. In addition, the flow of water reduces the density and viscosity of the medium, resulting in a laminar mode rapid deposition of particles with high density.

The total flow in the river bed diversion ditch divided into several streams, placing obstacles in the cross-section of the channel. Split one channel into multiple streams is an alternative to the extension channel. The decrease in the rate of flow may also be provided with accommodation in the vertical section of the flow obstacles. In this case, the deposition of heavy particles provide zones with low values of pressure, flow, caused by obstacles.

Method consider the example of a specific implementation.

Figure 1 presents the scheme of the debris flow GE the engineering field. Where: 1 is the accumulated stock of water, 2 - prepared subsoil, 3 - river bed diversion ditch, 4 - zone restructuring.

Initially create the accumulated stock of water 1 above fields and prepare the subsoil plot 2. For water accumulation can be used by melt water. The prepared subsoil plot is a pioneer pit, which provides the opening of the ore reserves from rukovodstvo ditches. During the accumulation of water and site preparation field training river bed diversion ditches 3 and forms a zone of restructuring 4, which will host the gravitational accumulation of productive particles. After the accumulation of water and the completion of the accumulated stock of water 1 released in a short period with the most possible consumption. The flow of water over rukovodstvo ditch enters the prepared subsoil plot 2, the kinetic energy produces the destruction of the array, involves him in the stream and river bed diversion ditch 3 moves to the area of restructuring 4. In the area of restructuring 4 is the deposition of suspended particles. Large lump material and heavy particles are deposited first. Clay particles remain in suspension for a long time. After lumpy material and heavy particles will be precipitated, water with suspended therein particles of clay Mat is the Rial is directed into the sump. To do this, pass the ditch from zone restructuring 4 to the tank and remove it from the restructuring of the whole pulp.
