A disadvantage of the known measuring device is the lack of the ability to simulate the effect on the respiratory system of real conditions that are characteristic of real mine workings

A well-known universal simulator that simulates the work of a person in isolating breathing apparatus (RF patent No. 2597574, published January 20, 2015), adopted as a prototype, a universal simulator includes an isolating breathing apparatus, a subsystem for assessing the physiological state of a person, including blood pressure sensors, heart rate temperature, as well as a sensor for recording pneumotachograms, a treadmill, a processor.

A disadvantage of the well-known universal simulator is the inability to simulate the effect on the performance of a person included in the industrial design of the insulating breathing apparatus of the real climatic and chemical parameters of mine air.

The technical result is the ability to assess the health of a person included in an isolated breathing apparatus when performing actions adequate to actions in real mine workings in the event of an emergency.

The technical result is achieved by the fact that the simulator is located in a simulator chamber, the geometrical dimensions of which correspond to the actual size of the mine working, and the casing is made of heat-insulated and lightproof materials, a ceiling beam is rigidly fixed to the ceiling of the simulator chamber, a device for heating and air cooling connected to temperature and humidity sensors that are installed on the side walls of the housing, and a gas tank connected to sensors for monitoring gas concentration installed nnym on the side walls of the camera body - the simulator, treadmill walking belt is spanned by the rotating cylinders, which are connected via a belt transmission. motor, and lifting mechanisms, and a load is attached to the ceiling beam located above the treadmill tape through a bearing with an adjustable rotation force.

The simulator for assessing human performance (Fig. 1) includes a camera simulator 9, consisting of a body made of heat-insulated and lightproof materials and a ceiling 11, on which a ceiling beam 24 is rigidly fixed, the geometric dimensions of the camera simulator correspond to the actual size of the mine workings. A device for cooling - heating 12 and a gas tank 15 are fixed on the ceiling 11 and are connected by temperature and humidity sensors 14 and gas concentration monitoring sensors 17 installed on the side walls of the camera body 17. The treadmill 7 consists of a moving belt 18 stretched on the rotating cylinders 20, which are connected via a belt drive 22 to the motor 21, and lifting mechanisms 23 located under the rotating cylinders 20. A railing 19 is installed along the edges of the treadmill. To the ceiling beam 24 a load 26 is attached above the moving belt 18 of the treadmill 7 through a bearing with an adjustable rotation force 25. The processor 8 is connected to the moving belt 18, lifting mechanisms 23 and a bearing with an adjustable rotation force 25.

Assessment of human performance based on the simulator is as follows. Before performing the performance assessment procedure, information about the values and dynamics of physical loads characterizing the activities of the miner during the occurrence, evacuation and liquidation of an emergency is entered into processor 8: the estimated speed of a person 2 in production, the route change in the production slope, the predicted physical loads that a worker must perform .

According to these data, the processor control unit determines the speed of movement of the moving belt 18 of the treadmill 7, as well as the force with which the load 26 should move. To create this force, the required mode of rotation of the bearing 22 is selected. Control the speed of the belt 15 of the treadmill 7 and its angle of inclination is performed using a motor 21 and a belt drive 22, which transmit rotation to the cylinders 20. To change the angle of the tape of the treadmill 7, lifting mechanisms 23 are used.

Due to the operation of the device for heating - cooling 12 in the chamber-simulator 9, the climatic parameters of internal air 13 are provided, which are identical to the same parameters in real mining. The control of these parameters is carried out by temperature and humidity sensors 14. In a similar way, a gas mode is created in the camera-simulator 9, similar to the mode in a real mine. For this, a gas reservoir 15 is used, from where gas 16 is supplied to the simulator chamber 9, the concentration of which is monitored by gas concentration monitoring sensors 17.

The test person 2 is mounted on the moving belt 18 of the treadmill 7. The balance of the person is ensured by the railing of the fence 19. An isolating breathing apparatus 1 is fixed on the person and blood pressure sensors 3, pulse rate 4, temperature 5 and registration of pneumotachograms 6, which transmit information about measurement data to processor 8.

During testing, in accordance with the specified conditions, the speed of the treadmill tape, its angle of inclination and physical activity are changed. Thus pnevmotahogrammy calculated based on a volumetric flow rate of inhaled and exhaled _breath Q Q _exhalation air during a respiratory cycle are used to determine the effective operating time person included in the self-contained breathing apparatus, i.e. time during which condition Q _expiration is fulfilled _. / Q _breath. > 1. Outside of this condition, the use of insulating breathing apparatus becomes impractical. Simultaneously with the volumetric flow rates of the inhaled Q _breath and the exhaled Q _breath , the blood pressure, pulse rate and temperature are also measured, which are used in the future to establish the physiological state of the subject.

On the basis of the tests, either the physiological capabilities of people to perform the required work in an isolating breathing apparatus are established, or the need for additional training is determined.

As shown by the results of mine tests of people included in an insulating breathing apparatus, which is almost 80% of the subjects, the duration of work in the breathing apparatus was less than the time required for people to leave the danger zone.
