Description

The invention relates to mountain production and can be used in the extraction of minerals, saneraiouinx under watercourses with low and medium water flow, when the displacement of the earth's surface occurs without the formation of dips. The purpose of the invention is to increase the safety of work and reduce the labor intensity of protective measures in the processing of water bodies.

In figo1. a vertical section is shown across the strike of the minerals; FIG. 2 is a plan of the site for the processing of a water body.

The method is carried out as follows.

Outside the underworking zone 1, a reservoir reservoir 2 is created and connected to it: the channel of the watercourse From the reservoir reservoir 2, a tight sectional telescopic conduit 3 (search, for example, from sections of metal, concrete pipes or grooves) is put through with a reservoir reservoir 2. The waterway 3 is placed on height-adjustable supports 4, which are installed on the surface of the underworking area. To control the position of the displacement trough; set rappers 5

In the process of the development of rocks in the field and the increase in the developed space associated with it, the overbalancing of the overburden and the development of displacement processes to the surface occur. Over time, the deformations on the surface areas adjacent to the worked-out space reach critical values, above which water may break into the underground workings. When critical deformations occur, the bed of the watercourse 6 is overlapped and the passage of the watercourse 6 through the working area of the storage reservoir 2 through the conduit 3 begins (the direction of the watercourse is shown in figure 1 by arrows)

The water level in the reservoir-reservoir 2 during periods characterized by low water consumption in the watercourse (summer, winter) is kept minimal with the aim of ensuring the possibility of receiving vodka water that exceeds the capacity of the conduit 3. The capacity of the conduit 3 and the volume of water

Ema accumulator 2 is calculated taking into account the possibility of passing water before the start of the next flood season. With a further decrease in the rocks and an increase in the surface deformations in the placement zone of the conduit 3, the flexure and stretching of the conduit occur. However, damage to the joint sections 7 and water leakage does not occur, since the telescopic structure of the conduit 3 and the presence of compensators (for example, bellows type or: rubber shells) allow mutual displacement of individual sections of the conduit without loss of waterproofing to the limits due to the design of compensators. When the developing deformations in the reworking zone exceed the critical ones (i.e. the capabilities of the compensators), the height of the waterway supports are adjusted in accordance with the profile of the earth surface displacement trough, which corresponds to bringing the waterway profile to its original position. Regular instrumental observations follow the profile of the displacement trough in the work of the water conduit, which makes it possible to ensure periodic adjustment of the conduit profile until the end of the mined rocks and surface displacement processes. The combination of the operations performed ensures a reliable rock formation against water breakthrough during the processing of water bodies and surface subsidence up to several meters.
