Mine disaster and accident
Miner's life safety is threatened
Severely affecting the production efficiency
Problems Caused by High Risks in the Coal Industry Problems Caused by High Risks in the Coal Industry
As the major coal producer in the world, China reached annual coal output ofnearly 3.5 billion tons in 2011, accounting for about 37% of the world 's totalcoal output, and maintains the high growth and high profit trend.
Due to its production characteristics, the coal industry has high risks such asthe permeable, roof fall, fire protection /extinguishing, coal and gas pop-out,gas and coal-dust explosion and so on, and the million tons death rate remainshigh
Although IT system has a good foundation, it is still in urgent need of strengtheninginformation exchange and sharing between the various systems to meet safetymonitoring, emergency rescue, production and management automation and otherneeds
Industry consolidation leads to the trend of large group development. In the process ofindustry concentration, overall information integration needs to be improved.
Industry Status
Six Systems
Mine communication system
Mine water supply rescue system
Mine compressed air self-rescue system
Monitoring and control system
Underground personnel positioning system
Underground emergency hedge system
It is becoming the focus of attention in the coal industry, and also the key point of the coalindustry IT systemsto build coal mine underground hedge system for effectively monitoring, forecasting anddealing with various disasters.
In 2011, the State Administration of Work Safety and State Administration of CoalMine Safetyjointly issued the Basic Specifications for Construction of Coal Mine UndergroundHedge facilities("Six Systems“)(Trial)
Mandatorily required
to be compliant before end of
June 2013.

Significance and role of M2M
Humane Care Targeted
Application status of existing mine M2M
Enabling capabilities of M2M devices and network technologies has reached application level
Automatic co-action of mining area systems as the prototype of M2M has a goodfoundation
Underground wireless communication system is more PHS – lack of the supportof data communication, and technically fall behind the mainstream wirelesscommunication technology of public network (3G)

Rich source of sensors – maybe the richest in all industrial environment, butinsufficient intelligence causes limited monitoring capacity of the environmentand equipments

M2M standalone can not solve all production and safety problems5
Bottleneck which affects further promotion and application of M2M in the coal industry is not technology or budget, but to convince decision-makers of mining area with further economic benefits of the M2M.

Monitor gas concentration, fan status and other parameters, and display them inthe ground workstation, reduce the underground inspection and on-dutypersonnel and help leaders and dispatchers grasp timely the production safetysituation. The entire system will play an important role in providing safety,improving production efficiency and other aspects.
With RF transmission and digital encoding identification technology, the system cansuccessfully identify the underground personnel and dynamic targets and reflect thedynamic situations of personnel and equipments in all underground areas to theground computer system, thus to enable management personnel to keep abreast ofdistribution of underground personnel and equipments and trajectory of each miner, soit is an important means to improve mine management level.

High growth and high profits to support long term M2M investment
Coal mine application basis and M2M technology development can already provide good support for intelligent mine deployment
Government regulation attaches great importance to coal production safety
M2M technology can effectively enhance the safety level of coal production
Need to accelerate the maturity level of mine M2M
applications and devices
Need to further explore the integration value of
M2M and mine safety production
Strengthen government supervision to urge coal
mines to improve safety and management by
approaches including M2M

With the development of sensors, sensor networks, mobile communications and automatic controltechnology, development trend of M2M applications in the coal industry will have the followingcharacteristics:
With increasingly improved bandwidth, coverage and disaster tolerance capacity of the mobile communication network, mobile broadband data network will be extended throughout the mine.
With the maturity of MEMS technology, it will achieve sensing of temperature, pressure, light, gas composition and other environmental parameters in small dimensions to lay a foundation for the multi-function integration of terminal.
The terminal carried by underground staff will be integrated with mobile communications, mobile office, precise positioning, equipment management, environmental monitoring, physical monitoring, disaster warning, hedge navigation and other functions and is characterized by lightweight and miniaturization.
