The limits of coal resources storage, which determines that the coal mine production is a process from growth to aging. The aging mines produce a lot of coal and simultaneously face many problems, such as unsatisfactory depositary conditions, insufficient reserves, simplex industrial structure, high energy consumption, low products extra value, and what’s more, the “waste” coal gangue, mine water, and waste heat are just ignored of their value and completely wasted. Based on comprehensive analysis of the current situation of the development of coal enterprises in china, the paper will research in the definition of aging mines and their development bottleneck, and connecting with the SWOT comprehensive analysis of the domestic and foreign aging coal mine’s low carbon development, the analysis proves that development of “it is the inevitable choice of aging mine to lose control of all kinds of adverse conditions, prolong the mine life cycle through the low carbon transition”. reference: Progress in Mine Safety Science and Engineering II (pp.1169-1174)

2. MAJOR FACTS
ØCoal is the major source of energy in China. In China
energy production and consumption of the coal is
very high, coal has always accounted for about 70%
of the proportion and power is the main flow of the
coal consumption.
ØIn 2007, coal accounted for only 27.8% of the world’s
primary energy consumption, while the number was
less than 20% as for most of the developed
countries, however in China’s energy consumption
was up to 69.5%.

4. Research Introduction
Based on comprehensive analysis of the current
situation of the development of coal enterprises in china,
the paper will research on the definition of aging mines
and their development bottleneck, and connecting with
the SWOT comprehensive analysis of the domestic and
foreign aging coal mine’s low carbon development.

5. Introduction
ØCoal mine production is a
process from growth to aging.
ØThe aging mines had produce a lot of coal and
simultaneously face many problems, such as
unsatisfactory depositary conditions, insufficient
reserves, simplex industrial structure, high energy
consumption, low product value , mine water and
heat completely wasted.

6. MINE LIFE CYCLE
— The formation of Mine
production capacity and the
end of the service cycle
experience from exploration,
infrastructure, commissioning
of production, stable to aging
(Change), this time span is
called the mine life cycle.

7. LIFE CYCLE OF COMMON MINE

8. LIFE CYCLE OF AGING MINE low
carbon development

9. DEFINITION OF AGING MINE
If mine aging period have these signs like exploitation
and consumption reserves are more than 2/3 of the
mine reserves or the service life is less than 10 years.
More than 60% of the production development of
mine is not stable or production began to decline,
daily output has dropped to the level of design
capability or stable ability.(According to Kailuan Coal
mine)

10. DEFINITION
Su evaluates weather a mine should be closed or
not its is based on the comprehensive evaluation of
the asset-liability ratio, economic losses and benefits
ofminingdepthandcoalresourcesetc.

qRESTRICITIONS OF
PRODUCTION SYSTEM
1. Production and safety
condition
2. Production layout

13. LIMITS OF RESOURCE STORAGE
Because of long time mining, the period of stable
and high production mining has passed. The
production is affected by the
— increase of mining depth,
— the weakening of mining conditions.
— shortage of available reserves and
— lack of ability

14. LIMIT OF PRODUCTION
EFFIENCY
Because of bad geological conditions, mining
working face causes more invalid footage increase
and increases the quantity of tunneling
engineering.
— Quality cannot be guaranteed.
— Marketing competition.
— Profit ability is also reduced.

15. LIMIT OF HUMAN RESOURCE
— The phenomenon of brain drain is serious in aging
coal mine.
— Reduced income for technical management
personnel.
— Personnel leaving.
— Lack of safety.

16. RESTRICITION OF PRODUCTION
SYSTEM
Coal production is a complex system. We need to go
through layout of production
— the resource exploration
— Project argumentation,
— feasibility of mine construction.
— safety and old equipment

17. SWOT ANALYSIS OF AGING
MINES LOW CARBON
DEVELOPOMENT

18. Strengths
ØPolicy support: National, provincial, coal group, own
policy supported system, which provides guidance for
the old mine developing low carbon economy.
ØFeasible technology: Many countries have done a lot
of research in sustainable development and low
carbon transformation and utilization of coalbed
methane exploration.

19. Strengths
ØSuitable Economy: The social and economic benefit from
developing low carbon economy is remarkable, which is
not only beneficial to the people and countries, but also
can make the coal enterprises turning around, self-
perfection, self-development and towards a low carbon
road of healthy development.

20. Weaknesses
— Resources condition characteristic: for the aging mines
having long mining history, the insufficient remaining
reserves, relatively backward production system and other
adverse conditions, which determines the single coal
production and operation to achieve the efficient
development of the coal mine is difficult.
— Lack of pioneering: Aging mine’s low carbon
development mode in our country is still in exploring stage
it is not much running low-carbon ecological mining
development mode of research and exploration of mine in
our country at present.

21. Opportunities
Ø Countries and world environment: industries in our country and the
world will be focused on the development of low carbon economy.
Ø The national policy and financial support: China clearly put
forward that "the state encourages and supports the development and
utilization of new energy and renewable energy”, the state will
introduce tax preferential policies, financial incentives and market
oriented.

22. THREATS
— Low Carbon economy development goals have formed the
dilemma in China’s development energy. This is not just a
technical upgrading, more important it is the development
of the industry a revolutionary change in concept. Facing
the current global inflation expectations, it must be a
problem that had been dealed with to keep the enterprise
value and profit growth, at the same time, technical
analysis and implement low carbon ecological mining,
construction, operation.
