“ELMIZ” PJSC was found in 1996 as a results of “Kyiv Radio Plant” restructuring according to the decision of the Cabinet of Ministers of Ukraine. The enterprise is located in industrial area of Kyiv – Darnitsa. Specificity of the enterprise – the production of sophisticated electronic hardware, control systems and digital automated devices. The enterprise includes design and technology bureau, service of technical control and manufacturing engineering support. Today the company is ready to offer for the mining industry  Automation and control systems for the mechanized complexes  Head lamp explosive-proof and with  Complex lighting stope in mine  Lighting systems for mining machines  Control systems of methane in the mine air

The lamp is intended for individual lighting of miner's workplace in the coal mines of all categories by the dust-gas regime. The lamp consists constructively of the following components: headlamp, in which the LED module with 2 light sources is installed for operational and emergency lighting, mode switch. The fixing of the accumulator battery on the belt of the miner is performed with metal brackets. The headlamp is connected to the battery via a flexible electrical cord with a length of 1400mm.

. The lamp combined with the methane signaling device is intended for automatic control of the content of methane in the mine air and for the generation of light signals when the maximum permissible values ​​ of the volume fraction of methane. The signaling device has the following features and capabilities: when it reaches the intermediate operating threshold (2% or 1%) and more than volume fraction of methane in the air, the light source switches into an intermittent operation mode with a frequency of 1 Hz; when it reaches the upper operating threshold (2,5% or 1,5%) and more than volume fraction of methane in the air, the light source switches into an intermittent operation mode with a frequency of 10 Hz; operation in an emergency mode when the accumulator battery voltage is below the lower threshold; disconnection of the power source when short circuit in the power circuits.

Process Control module digital warning of methane is intended for setup, calibration and verification of digital mine methane sensors of type "LUX SM.01" and "LUX SM.TS.“ MPC provides:  software configuration of the sensor current range from 5 mA to 160 mA; l  control voltage on the battery alarm;  software configuration signaling methane (calibration by applying calibration gas mixtures;  software installation value thresholds in% volume fraction of methane:  first threshold in the range from 0 to 2.5% by volume. the proportion of methane;  second threshold automatically to about 0.5%. the proportion of methane over the first threshold;  control thresholds specified in% volume fraction of methane;  indication of the measured values ​​ of signaling the concentration of methane.

Laser rangefinder mine LRM v. “MLR-1” is designed to measure distances and angles in underground mines, including those which are hazardous on gas and/ or dust. “MLR-1” provides protection against natural and mechanical effects. He doesn`t afraid of falling from a height of 2 meters, falling into the water, dust and splashes. Degree of protection – IP 65. Display`s backlight and its multiline provides the best reading. Also MLR1s-1 integrated with angle change sensor, so it can be used as angle meter. “MLR-1” can perform calculations with the measured values: subtraction, addition, the definition of area, volume, etc… “MLR-1” stores in memory the last 20 measurements

The complex lighting mining machinery (KOGM.01) The complex is intended for lighting workplace of driver mining machines and area of coal mines, including dangerous on gas (methane) and (or) coal dust. As the light source lamp uses high-brightness white LEDs. Operation conditions:: - Environment temperature from -10 ° C to 35 ° C. - Relative humidity (98 ± 2)% ( with condensing humidity) at a temperature (35 ± 2) ° C. The complex includes:, lamp and power supply AGATE VH

Complex lighting stope of mine (CLSM) Complex is intended for lighting stope of mine, equipped with mechanized complexes. The light sources used high-brightness white LEDs. Operation conditions: - Environment temperature from -10 ° C to 35 ° C. - Relative humidity (98 ± 2)% (condensing humidity) at a temperature (35 ± 2) ° C CLSM consists of a power supply and the lamps Number of power supplies and lamps determined by the length of the working face. Each power supply provides power to 16 lamps.

The control unit for the methane mining machines Intended for automatic control of the content of methane in the mine air, issuing a warning signal and disabling the mining machine, when the level of methane in the mine air above a predetermined level. As the sensor is used thermocatalytic sensor (sensor) methane, and as a power supply - lithium - ion battery. Provides automatic control of the percentage of methane in the air mines and software installation of two values of a given level (level: the first and second) in the proportion the methane contained in mine air.  Installation of the first range of the trigger level of 1% to 2% ;  The second trigger level is automatically set at 0.5% above the intermediate level triggering, ranging from 1.5% to 2.5% in the share of methane content. Provides issue a warning (sound) signal when exceeding the first level triggering, as well as the issuance of the signal equipment mining machine. It provides mechanisms mining machine off when exceeding the second level of operation. Rated supply voltage, V Maximum deviation, V 3,7 plus 0,55 / minus 0,7 Sound pressure level at a distance of 0.5 m from the unit in the audio alarm, no less, dB 80 Continuous operation without recharging the battery, an hour, no less: 14 Maximum permissible absolute error in the v. fr. of methane 4,%, no more ±0,2 Warm-up time, min, no more 10 Response time for v.fr. of methan, s, no more 8 Tripping current protection, A, no more 2,5 Efficiency, no less 0,75 Battery Li-ion The capacity of the battery, not less mAh 7000 Degree of protection against external influences IP66
