The invention relates to the mining industry and can be used in conditions of salt and potash mines.

There is a method of cleaning sump skip shaft at which cleaning is carried out with the help of tripping skip, which moves in an oblique way by means of the winch, and sumptuous part of the trunk posted by detecting the bunker with a sector gate (Tyutyunik YA Design and construction of pit yards mines / Tyutyunik YA, Koptelov S. p., Svirsky SCI - M.: Nedra, 1983, str-105).

However, this method is difficult to operate, there is also the possibility of flooding of the equipment and the risk of blockages in the period of repair works.

Closest to the proposed invention is a method of cleaning a well, which consists in the transportation of spillage into the car to horizontal move below the horizon unloading yard from the sump of the skip shaft to cage barrel, while constructing the United sumptuous pumping stand in the trunk (Tyutyunik YA Design and construction of pit yards mines / Tyutyunik YA, Koptelov S. p., Svirsky SCI - M.: Nedra, 1983, p.106, 4.8).

The disadvantages of the described method is the presence in the trunk capture the bunker in which transform your cake and have problems with it unloading, you must have elektrobosna the transport and lifting of spillage in the car on the surface, when you want to load the cart in the sump and discharge on the surface, resulting scheme is complex and time-consuming.

The technical result of the invention is to significantly simplify the cleaning of the sump and the reduction of complexity, it does not require the construction of catching bin and avoids the problems associated with the release of spillage from him.

To achieve the technical result in the cleaning method of the shaft sump after accumulation of spillage, including the sinking of production to clean the sump and its connection to the sump so that the soil production to clean the sump at the connection point is located at the level of the bottom of the barrel, the construction of a sump located outside of the barrel, and its linkage with development to clean the sump, mechanized cleaning of the sump, when subjected to the transport draft on the horizon cleaning of the sump, then pass the sump, and production for cleaning sump pass with a slope towards the sump and clean the sump is carried out by delivery of spillage on transport to the slope.

In addition, cleaning of the sump and transportation spillage produce load-haul machine and transport the slope are the main horizon and cleaning of the sump is performed with the unloading of ore spillage conveyor or about exactly bunker this horizon, during this transport the slope are the mining horizon and unloading of spillage is carried out in the mined-out area of the horizon, spillage transport conveyor mounted on the transport slope production to clean the sump connect two or more trunks and arrange the merged header.

The essence of the technical solution is illustrated by drawings, where: figure 1 is a diagram of the workings for cleaning sump; figure 2 - section a-a in figure 1; figure 3 is a cross-section B-B in figure 1; figure 4 is a diagram of the workings cleaning jumptv 2 shafts; figure 5 - a section b-b In figure 4.

The method is as follows.

From the primary (transport) horizon 1 are transport slope 2 on the horizon cleaning of the sump, which is located below the camera boot device (1, 2, 3). Then pass the sump 3, located outside of the barrel, and production to clean the sump 4, which hit with the barrel 5 in his sumptuous parts so that the soil production to clean the sump 4 in place of the breakthrough is at the level of the bottom of the barrel, and the formulation for cleaning of sump 4 has a slope towards the sump 3 to drain the water coming out of the barrel 5. The water tank 3 is equipped with a pumping unit for pumping water into the Central sump For the accumulation of spillage in the shaft sump 5 it clear mechanized way is, for example, load-haul machine. Loaded in the bucket load-haul-dumpers spillage delivered to the main horizon 1, where unload ore conveyor or directly into mine bunker this horizon.

In some cases, such as when the chamber system development, transport slope 2 on the horizon cleaning sump are the mining horizon and delivered by the transport slope 2 spillage unload in a goaf (camera) this horizon.

Under the Central scheme of opening a mine field when on one site, there are several cargo trunks, their zumpfe can be interconnected generation cleaning jumptv 4, as shown in figure 4, 5, and between the trunks 5 be merged header.

If substantial lengths of the transport slope 2 it can be installed in the pipeline. In this case, the spillage from the bucket load-haul-dumpers unload on the conveyor, transported her to the main horizon 1, where overload on the ore line.

The proposed method can greatly simplify the cleaning of the sump and thus reduce the costs of these works.

1. The cleaning method of the shaft sump after accumulation of spillage, including the sinking of production to clean the sump and its connection to the sump so that the soil in the processing to clean the sump at the connection point is located at the level of the bottom of the barrel, the construction of a sump located outside of the barrel, and its linkage with development to clean the sump, mechanized cleaning of the sump, characterized in that undergo transport draft on the horizon cleaning of the sump, then pass the sump, and production for cleaning sump pass with a slope towards the sump and clean the sump is carried out by delivery of spillage transport gradient.
