Description

The invention relates to lowering the level of groundwater in underground workings, in particular, to devices for drainage from mines. A well-known mine drainage installation, including, and a pumping chamber with pumping units, a catchment basin, a preliminary sump, a sump, pipes and automatic control equipment for level sensors 1. The closest to the proposed one is a mine drainage installation, including an emergency and regulating catchment basin, a pumping chamber pumps, dividing walls, overflow pipes with gate valves installed in them, an overflow bridge located in an emergency water collector drain pipe The output end of which is connected to a regulating water collector, a waterway walker with a groove and an automatic control system with level sensors 2. The disadvantages of the known installations are the increase in the volume of underground workings in the near-barrel yard and the need for auxiliary pumps, which reduces reliability and increases capital costs. The purpose of the invention is to increase the reliability of work and reduce capital costs. The goal is achieved by the fact that in a mine drainage installation, including an emergency and adjusting water tanks, a pump chamber with pumps, dividing walls, overflow pipes with valves installed in them, an overflow jumper located in the emergency water collector drain pipe, the output end of which is connected to the adjustment water tank. , hydraulically operated walker with a groove and an automatic control system with level sensors, the adjusting water tank is made as axial chamber of horizontal generation and adjacent to one part of it at the right angle of inclined excavation, the other end of which is connected to the water-supply walker, the emergency water collector is connected to the other part of the horizontal development and water-supplying walkway, the dividing walls are installed across an inclined working and an emergency water collector in the place of their connection with a horizontal working; an overflow jumper is placed at the water supplying station across the inclined working, The upper edge of the jumper is located at the level of the emergency level sensor, an additional groove is made in front of the jumper in the inclined excavation with a slope towards the emergency water collector, and the drain pipe is connected to the main inlet rail groove by the input end. In this case, the dividing wall installed in the emergency water collector is provided with an additional pipe with a valve, and the drain pipe is located along the horizontal development of the outlet, which has nozzles with locking devices in the number of pumps. FIG. 1 schematically shows the proposed drainage installation plan; in fig. 2 shows section A-B-B in FIG. one; in fig. 3 shows a section of the GD-E in FIG. one; in fig. 4 shows a section of an Ж-Ж in FIG. one; in fig. 5 shows section 3-3 in FIG. 1. The mine water pumping installation has a pumping chamber 1, pumps 2 with receiving devices 3, an adjusting water collector consisting of a horizontal production 4, an inclined production 5, which is separated from the horizontal production 4 by a continuous separation wall 6 in which the pipe 7 with a normally open valve 8, installed at the point of junction of the inclined production 5 to the inlet of the walker 9, the overflow jumper 10, the upper edge of which is located on the mark of the alarm level sensor of the automatic control system (not shown), an emergency water collector 11, a transverse groove 12, made before the jumper 10 with a slope to the collector 11 and the groove 13 of the water carrier walk 9. The emergency water collector 11 adjoins the water guide walk 9 with bend 14, and the horizontal water tank 4 is separated from the horizontal water reservoir a dividing wall 15 through which the drain pipe 16 runs along the entire catchment basin 11 with a constant inclination from the groove 13 and an additional pipe 17 equipped with a normally closed gate 18. The pipeline 16 has a put, along the horizontal generation 4 outlet 19 with nozzles 20 by the number of pumps in the installation. Each nozzle 20 has a locking device 21 and is lowered into the individual when the pump 2 is in the bottom part of the horizontal output 4 of the adjusting sump. The mine drainage installation works as follows. The water inflow from the water supply walk 9 through the groove 13 enters the drain pipe 16 of the emergency water collector 11, then through the open valves 21 into the bottom part of the horizontal production 4 of the adjusting water collector, from where it is pumped out through the receiving device 3 of the pump 2 together with sludge to the surface. With non-operating pumps 2 or an inflow exceeding the supply of one of the working pumps, water fills the horizontal output 4 of the adjusting pump.

collector and through a normally open valve 8 enters the inclined production 5 of the adjusting catchment basin. During a prolonged forced shutdown of the pumps 2, the water, having filled the outlet 5, is poured over the overflow bridge 10, the upper edge of which is at the level of the alarm level sensor. At the same time, the water along the groove 12 enters the emergency collection tank 11 and fills it. After eliminating the causes of the forced stop and switching on of the pumps 2, the valve 18 is closed, and the emergency water collector 11 is pumped out, after which the valve 18 is closed. Since the emergency sump 11 fills the water clarified after overflowing through jumper 10, it does not slurry and can be performed horizontally or with a slope of up to 0.005. The adjusting sump is emptied through a permanently open valve 8. The shorter length and the absence of bend at the point of abutment to the water walker 9 allow you to perform / generate 5 of the adjusting water collector with a slope providing flushing, and the presence of jumper 10 makes it possible, despite the absence of bend, make full use of production capacity 5.

The proposed implementation of mine drainage installation does not require the construction of the workings of the preliminary sump and auxiliary tank. The horizontal development of the adjusting sump combines the functions of a sump well and auxiliary tank, and a settling tank separating a large slurry suspension,

individual impressions of this output are used for each pump, which allows to increase the reliability of the installation and reduce the capital costs of its construction.
