Abstract

The invention relates to the mining industry and is intended for transporting rock mass through ore passes. The purpose of the invention is to increase safety and improve sanitary and hygienic working conditions during the exploitation of ore passes in flooded deposits. The escape route includes the barrel and bunker parts (warheads) 1. In parallel, the warhead 1 is made to control recovery output 3. At the same time, the warhead 1 and output 3 are connected with a slope 4. having filters 1 on the side of the warhead 1. On the production side 3, there is an air intake pipeline and shut-off control and signaling equipment. In the presence of the clay mass in the output of clay fractions in warhead 1, a water column is formed. The slope angle of the coupling is 15-30 °. The skopivan from the water is discharged through conduit 6 to the drainage ditch. In case of increased water supply, the alarm is automatically activated and the discharge of the rock mass is stopped. 2 and.h. T oo 00 about N

Description

The invention relates to the mining industry and can be used in the development of flooded deposits with the transportation of rock in ore passes.

The aim of the invention is to improve safety and improve sanitary and hygienic working conditions during the exploitation of ore passes in watered deposits.

10, the water is discharged through conduit 6 into the drainage ditch 12 of the haulage output 13. In the case of high water inflow, which is recorded by flow meters, an alarm is automatically activated, the output of the rock mass is stopped. After removal of water from the bunker part of the ore-channel 1, if necessary, the filters 7 are washed or purged with the help of an air-air pipeline 8. In case of increased water inflow

FIG. 1 shows the ore pass, a longitudinal section along the axis; in fig. 2 shows section A-A in FIG. one.

The escape route consists of barrel and bunker parts 1. The bunker part is filled with watered mountain mass 2, and in parallel, the bunker part 1 is made of control rising production 3. Production 1 and 3 are connected by an inclined cover 4, in which the jumper 5 is waterproof.

The latter is equipped with two drain 20 switching on the emergency pump, pipelines 6 (working and reserve),

Claims (1)

which are from the side of the bunker part 1 filters 7, for example slotted or tubular, and from the control output 3, a restroom, including a receiver and bunker-air pipeline 8, a locking part, a control rising signal and a control signaling treatment connected to the bunker part 9 sleeves and jumpers installed in the cage, characterized in that, for to improve safety and improve sanitary and hygienic working conditions during the exploitation of ore passes in flooded deposits, the connections are inclined towards the bunker part, and the jumpers are made waterproof and equipped with The proposed device works as follows. If clay mass is present in the flooded mountain mass in the bunker part of ore-landing I, a water column is formed and water 10 is accumulated under the roof 11 of the inclined siding 4. At the same time, the slanted tilt angle is 15-30 °. The soil of the oblique coupling from the place of erection of a waterproof jumper 5 to the bunker part 1 of the ore landing is made at an angle greater than or equal to the angle of ec30 to avoid accumulation of rock mass 35 at least two drain pipes with filters installed on the side of the bunker part, a water-air pipeline, shut-off and control and signaling equipment installed on the side of control generation. natural slope of the rock mass 45-50 °. The slope of the coupling 4 has a waterproof jumper 5, for example, of concrete, in the upper part of which is sealed two drain pipes 6 (working and back-up) of large diameter with tips in the form of perforated (slotted) filters 7. The drain pipe 6 is equipped with a water-supply pipe 8, shut-off and control and signaling equipment 9. Accumulated water is drained through pipeline 6 into the drain ditch 12 haulage output 13. In the case of increased water inflow, which is fixed by flow meters, an alarm is automatically activated, the output of the rock mass is stopped. After removal of water from the bunker part of the ore-channel 1, if necessary, the filters 7 are washed or purged with the help of an air-air pipeline 8. In case of increased water inflow 35 at least two drain pipes with filters installed on the side of the bunker part, a water-air pipeline, shut-off and control and signaling equipment installed on the side of control generation.
