Coal City Analysis of factors affecting the strategic reserve

[Abstract] as China's urbanization process is accelerating, China's cities, especially the lack of one type of energy has become China's major cities big consumers of energy, number and size in the year to year. Coal reserves in China accounted for about 90% of reserves of mineral resources, accounting for the proportion of fossil energy is 95%, very resource potential, therefore, the coal reserves even more necessary. the establishment of coal-based energy Development Strategy, the establishment of coal-based energy Strategy for urban reserve system , is the city break the bottleneck of energy, sustainable Development, the inevitable choice. This paper focuses on how to build coal-based reserve system of the city's overall energy Strategy goals, the strategic reserves of coal, the impact of factors were analyzed.

[Keywords] coal, strategic reserve, factors

For the city in a strategic coal reserve will help take preventive measures to reduce business costs to run the city, is conducive to Economic growth and we see from the industrial structure changes, the world's manufacturing center of China has transferred the manufacturing sector in China's rapid Development, the need energy, and infrastructure to follow up. reasonably determine the size of strategic reserve of coal required to consider the following factors.

1 From the demand point of view to determine the safety limits
Safety margin to ensure the consumption of coal in the valley and city crisis and certain emergency situations that can put a reserve supply of coal the size of the cities the size of coal reserves need to consider the city's energy consumption patterns, as well as coal supply and demand situation and trends.

Type of urban energy consumption, energy supply and demand ratio can be defined: one is the city's own energy supply and demand ratio of total primary energy supply divided by the city's proportion of total primary energy demand, and city resources for this indicator, which reflects the city energy self-sufficiency the ability to reflect the energy level of Development of mining industry. the second is the city's own energy supply and demand than the second divided by the total energy supply of the city twice the proportion of total energy demand, it does not reflect the city's energy self-sufficiency, is outside the city will reflect the primary energy into secondary energy capacity, reflecting the city's level of Development of energy conversion industries. Ep reflect energy production elasticity of energy growth and the relationship between urban Economic growth, specifically the amount of annual energy production average annual GDP growth rate of urban growth and the ratio of the energy consumption elasticity Ec reflect the growth of energy consumption and the relationship between urban Economic growth, the specific energy consumption of the average annual urban growth rate and the ratio of average annual GDP growth rate, according to the four indicators, we can the city be divided into two dimensions of space, divided into four types. four types based on the city's energy dependence and the adequacy to the city is divided into energy-Ⅰ, energy-oriented city Ⅱ, energy dependent and energy-dependent urban city Ⅰ Ⅱ, as shown, the table below.

With the implementation of the concept of environment protection and energy, with low-carbon economy, raising the level of energy technology, energy technology and conservation of the cycle was, can be expected to, a double-low situation, and energy-producing city of elasticity Ep <1, energy-dependent city's energy consumption elasticity Ec <1.

2 From the supply point of view to determine the total amount of coal reserves
Coal reserves in the city should analyze the international market and domestic coal resources on the basis of the status and trends, combined with the coal transport capacity on the basis of analysis of the total coal city available. But also distinguish between urban type of energy, coal reserves in determining a reasonable size , the need to combine the status of urban energy types and supply analysis of trends.

3 From the point of view to determine the Economic limits of ability to pay
Economic limits on the government's financial ability is dependent on government subsidies to the coal strategic reserve capacity to pay, which is different from the city's financial situation and the willingness to pay, which is temporarily as the focus of this study.

4 Other factors
Strategic reserves of coal the size of the city need to consider the urban design of geographic location, resource endowment, locational advantages, the management level.

I believe that the strategic reserves of coal, the main objective is to protect the city's energy supply security, coal strategic reserve design should first consider the size of the coal supply and demand balance, other factors such as economic benefits, also have taken into account.
