Description

The invention relates to the mining industry and can be used to protect and evacuate miners from dead-end openings with sudden gas emissions, gas contamination of the openings and the occurrence of a fire in them.

A device is known for evacuating miners using a ladder placed in a rigid ventilation pipe and driven by a traction rope connected to the winch [ed. testimonial. USSR No. 742606, publ. 06/25/1980].

The disadvantages of the known device are that the ladder, which is constantly located in the ventilation pipe, creates additional resistance to the ventilation flow pumped by the local ventilation fan, and the hole in the wall of the ventilation pipe through which the traction cable connects the drain to the winch creates a risk of air leakage and loss of depression in the ventilation system.

A device is known for ventilating mine workings and evacuating miners in an emergency, comprising a 1220 mm steel rigid pipe located in a dead end mine with a wall thickness of 16 mm, equipped with branches, in which locks are installed, connected in series to the pipeline through garage chambers on one side and with entrances for miners on the other hand. In an emergency, miners enter the garage chamber, attach themselves to vehicles (electric cars, cycle cars, etc.) and move along the pipeline to the surface [ed. testimonial. SU No. 1420188, publ. 08/30/1988].

A disadvantage of the known device is the high cost of manufacturing and installing a ventilation pipe of significant diameter and wall thickness, as well as the lack of protection for miners evacuated through the pipeline from high temperatures in the event of a fire in a mine.

The task of the invention is to enable a vehicle to quickly evacuate miners from dead-end workings in the event of emergency situations: sudden gas emissions, gas contamination of workings or a fire occurring in them.

This is achieved in that the device for the evacuation of miners in an emergency, including a vehicle located in a dead end mine, is characterized in that the vehicle is made in the form of a rescue capsule with a diameter of 0.8-1.0 m and a length of 3 to 4 m, with the possibility of moving along a monorail made of heat-resistant steel, mounted on the wall of a dead-end mine at a height of 0.7-1.0 m from the base, while the rescue capsule is equipped with a sealing hatch, equipped with thermal insulation located between the outer and inner walls of the rescue capsule, and the air regeneration system.

The size of the rescue capsule is justified by the feasibility of compactness, which does not interfere with mining operations in the face and ventilation of the dead-end mine.

Reducing the diameter of the rescue capsule to less than 0.8 m will make it difficult for miners who are caught in an emergency to land in it. Exceeding the diameter of the rescue capsule more than 1 m will lead to an unjustified increase in its dimensions and load on the monorail.

The length of the rescue capsule from 3 to 4 m was selected in order to ensure the possibility of placing two miners in it. As a rule, it is precisely this number of miners employed in mining in the face of a dead end mine. The length of the rescue capsule less than 3 m will create the risk of the impossibility of simultaneously placing two miners in it and the need for two rescue flights, which is not always feasible in the event of a fire. The length of the rescue capsule over 4 m will again lead to an unjustified increase in its dimensions and load on the monorail.

The advantage of moving the rescue capsule along the monorail provides greater reliability of operation of the inventive rescue equipment in comparison with 2-rail in the event of a fire and their deformation under the influence of high temperatures. The risk of deformation is reduced by the heat-resistant steel of which the monorail is made.

Placing a monorail on the wall of a dead-end mine at a height of 0.7-1.0 m from the base does not interfere with the operation of mining machines, and also ensures the safety of miners who are caught in a dead-end accident by landing in a rescue capsule. Placing a monorail at an altitude of less than 0.7 m from the base of the mine carries the risk of jamming of the moving rescue capsule with spills or rock fragments. Placing a monorail at a height of more than 1 m from the base of the mine can lead to the fact that landing in a rescue capsule in emergency conditions can be difficult, since the combustion products, in the first place, always accumulate at the base of the mine.

Placing heat insulation between the outer and inner hard walls of the rescue capsule eliminates the risk of its destruction when pieces of rock fall. The presence of thermal insulation in the rescue capsule provides protection for the evacuated from the emergency development from exposure to high temperatures.

The air regeneration system provides the opportunity for a favorable stay in it, without resorting to the use of additional means of using air supply.

The inventive device is illustrated graphically. In FIG. 1 shows a general view of the rescue capsule and its placement in a dead end mine, where 1 is the rescue capsule, 2 is the hatch, 3 is the monorail, 4 is the side of the excavation, 5 are the wheels mounted on the rescue capsule, 6 is the air regeneration system.

The device operates as follows. In the event of an emergency (fire, sudden release of gas, the gas of a dead end), miners are placed in capsule 1 and seal it with the help of hatch 2. During sealing, the air regeneration system is started 6. The rescue capsule equipped with wheels moves along the monorail 3 fixed to side of 4 dead-end mining. The movement of the rescue capsule along the monorail is carried out using an electric motor (not shown), powered from a mine electrical network or from a battery (not shown).

The advantages of the claimed device are the ability to quickly evacuate miners from gassed or smoky zones or areas with high temperature.
