EMAG - Automation and Safety Systems

EMAG is a research and development institute (established in 1975). With many years' tradition and experience, EMAG is a leading centre in safety systems and automation in the mining industry.

The institute holds a PN-EN ISO9001:2001 certificate, as well as accreditation certificates for the attestation department and testing and calibration laboratory. EMAG owns anechoic, an Electro Magnetic Compatibility (EMC) testing chamber.

EMAG has relations with France, Germany, UK, the Federation of Russia, the Belarus Republic, Ukraine, Czech Republic, Turkey, China, India, the US and Republic of South Africa.

EMAG specialises in mining industry projects:

• Complex monitoring systems for natural hazards and fire hazards
• Coal quality on-line monitoring and control systems
• Systems for monitoring, supervisory and visualisation of technological processes (underground mining, transport and ventilation of mines)
• Systems and devices for automation and mechanisation of mining processes
• Telecommunication, informative and control systems
• Electrical power and engineering switching-control equipment
• Monitoring of seismic hazards
• Calibration of measuring instruments for electrical quantities and testing of electrical devices for the mining industry

MEASURING SYSTEMS AND SENSORS TO CONTROL GAS, FIRE AND SEISMIC HAZARDS

SMP-NTA - monitoring system of methane and fire hazards in underground workings, with automatic electric energy switching-off at areas under explosive conditions.The system collects and records data about ventilation processes.

KTC-1 - designed for video monitoring of industrial objects, especially for methane and coal dust explosion-hazardous mine plants. Picture preview controlled from several camcorders, high picture quality in low light conditions, with remote setting.

ARES-5/E - provides complex assessment of rock-burst hazards within long wall areas and is adapted for use in potentially explosive areas.

ARAMIS M /E - designed for recording and studying of micro seismic events, as well as location of tremors and their energy evaluation. The system provides intrinsically safe, digital data transmission.

ARP 2000 P/E - monitoring system of vibration and movement of ground and buildings for tremor hazardous areas.

GEOTOMO/E - monitoring of variation in seismic wave suppression in coal bed and roof, by geo-tomography systems.

MINING PROCESS AUTOMATION SYSTEMS

EMAG provides the MAKS-DBC, which enables the radio control and current diagnostics of high-duty machines (coal cutter-loaders).The company also offers the NaP- chain stretch system for Armoured Face Conveyors (FCA), as well as the SUK – control system for Heading Machine. Available control devices include signal concentrators designed for operation under rugged conditions, sensors, valves, hydraulic and pneumatic distributors.

MINING TRANSPORTATION BELTS

The EMAG ZKL1 and MSPP transportation automation systems control belt conveyers in straight and branched paths of haulage, with visualisation of the system operation condition.

MINERAL PROCESSING

• BOSS 2000 - automated control of air-pulsated jig
• C - isotopic densimeter that provides density measurement of liquid/solids and gas/solids mixtures flowing through pipelines

MINING MACHINE DRIVE MONITORING

• KT-6 – converter for smooth rotational regulation of up-to 3, 150kW drives supplied with 6kV voltage (fans, pumps, compressors)
• ZK-6/2 – set for compensation of reactive power in underground power networks 6kV

COAL QUALITY MONITORING

• RODOS – ash monitor (without isotope – measurement of coal natural gamma radiation) for continuous determination of ash content in hard and brown coal, transported by belt conveyor
• ALFA-05/3E – on-line measurement of ash and moisture content in coal and calculation of calorific value of fine coal transported by belt conveyors
• GAMMA NATURA – laboratory-technological device for fast and accurate measurement of ash content, moisture and estimation of calorific value of coal. Enables archiving of measurement results and creating reports on coal quality. Can be used and stored in any indoor space
• PYLOX – fast determination of non-combustible solids content in dusts, sampled from coal dust-explosion protective areas; measurement of ash and total sulphur content in coal, under laboratory conditions
• WALKER– (without isotope – measurement of coal natural gamma radiation) fast measurement of ash content in coal at stockyard, in tanks, wagons and trucks.
• FOTOPYLOX – immediate evaluation of coal-dust explosion hazard directly at mine workings

MINING SWITCHGEARS MANOEUVRING EQUIPMENT

EMAG offers the SP-250, SP-400 vacuum contactors RP-250, RP-400, RP 250-0 vacuum interrupters to switch-over inductive motors that operate under hard environmental conditions or at starting and reversion. Also, the company manufactures WP 630, RRgFx/M protection for low voltage networks that supply the frequency converters, RRgB set of interlocking protection units, SOZ-05/II selective system of ground-fault protection for multioutlet networks.

ACCEPTANCE TESTING, EXPERTISE, TRAINING, PUBLICATION

EMAG provides acceptance and design testing of electrical equipment to be used underground in mines (accreditation certificates, notification); as well as specialistic training and the scientific-technical publications: Mechanizacja i Automatyzacja Górnictwa (monthly), monographs.
