for coal mine safety, from 2005 to now, we have pumped a lot of gas every year, but the gas emission is increasing, because the utilization rate of coal mine gas is too low. " On July 10, at the Sino British clean coal forum hosted by the British Consulate General in Chongqing Guizhou Provincial Energy Bureau, Zheng Mingjie, vice president of Guizhou environmental science research Design Institute, pointed out that by 2015, China's gas drainage capacity will be promoted according to the plan, which can be basically achieved. However, the utilization rate of vas is too low to achieve the goal of 60%.

"Guizhou as the main coal producing province, the coal production in Southwest China is not high, but the gas drainage volume is not low, so the gas drainage utilization potential in Southwest China is great." Zheng Mingjie said that for every ton of coal produced, the gas emission intensity of coal mines in Guizhou is as high as 6.32, that in Southwest China is 3.94, far higher than the national average of 1.49.

in his opinion, as a clean use of coal, China's coal mine gas commercial still has a long way to go, but at present most projects rely on government incentives financial subsidies, the core of coal-bed methane utilization is financing innovation.

"Twelfth Five Year Plan" target venting

according to the "Twelfth Five Year Plan" of CBM development utilization, China's CBM production will reach 30 billion cubic meters in 2015, including 16 billion cubic meters of surface development, basically all of them are used, 14 billion cubic meters of coal mine gas drainage, with the utilization rate of more than 60%.

"goals are difficult to achieve. Last year, the drainage volume of coalbed methane (commonly known as coal mine gas) in Guizhou was nearly 2 billion cubic meters, the utilization rate was only about 20%, a large number of resources were wasted. " Zheng Mingjie said. The coal reserves of

are mainly in Guizhou. The total coal reserves of Guizhou Province are 2.754 billion tons, ranking the first in China. The reserves of coalbed methane resources in Guizhou are as high as 3.15 trillion cubic meters, ranking the second in China. Compared with the development utilization of coalbed methane in Guizhou Province,

are not optimistic. Last year, Shanxi's CBM pumping capacity reached 52.5 cubic meters, but its utilization rate was only about 30%. Anhui Henan are the top coal-bed methane extraction amount, but the extraction amount utilization rate are not high.

"only Chongqing has a small amount of CBM extraction, but its utilization rate is almost 80% Last year, 530 million cubic meters of coal-bed methane were pumped from Chongqing, the country's center, last year, Zheng said.

"this is because Chongqing energy investment group controls the vast majority of coal resources in Chongqing, which is convenient for centralized management." Zheng Mingjie said that the group attaches great importance to the use of gas. For example, all the gas extracted from Zhongliangshan coal mine is used as gas. At present, the use of gas instead of coal mining has become the main business of Zhongliangshan coal mine. As early as 2006, Chongqing energy investment group used 189 million cubic meters of gas, the utilization rate was as high as 69.7%

, but this is a small number after all. On June 18, Feng Yue, chairman of Chongqing energy investment group, also said in an interview with the 21st century economic reporter that the Group intends to consider withdrawing from coal mines with poor resource endowment unsafe safety under the slowdown of power generation enterprises' dem. It is very difficult to increase the annual pumping capacity of coalbed methane in this city in the short term. The public data of

show that by 2010, the gas drainage volume of coal mines in China will reach 9.1 billion cubic meters, including 7.6 billion cubic meters of underground gas drainage 1.5 billion cubic meters of surface coal-bed methane. The goal of "10 billion cubic meters of gas drainage" proposed in the eleventh five year plan has not been realized.

"now it seems that we can achieve or even exceed the CBM extraction capacity planned by the state during the 12th Five Year Plan period, but it is difficult to use 60% of the CBM, which indicates that there are many difficulties." Zheng Mingjie said.

he said that in order to realize the commercial utilization of coal mine gas, there are many constraints, such as the lack of technology, the lack of funds, the difficulty in obtaining the exploration mining rights of coalbed methane resources.

take Guizhou as an example. The coal seams are thin, the spacing is small, the permeability is low. The whole province only stays in the situation of gas drainage in coal mines. Yuan Liang, an academician of the Chinese Academy of engineering, pointed out that the CBM wells in the United States can achieve a daily output of tens of thouss of cubic meters. In China, the average output is 2000 cubic meters, the maximum daily output is 5000 cubic meters. Even many wells can not produce gas, there is still a technical breakthrough. In China, CBM is mainly used for power generation, but its extraction efficiency is still too low Zheng Mingjie said.

"the conflict between coal mining rights gas mine rights is also a problem. Many large coal industry groups can not own gas rights in the development of coalbed methane, which is often unable to be solved by local governments or coal mining enterprises." Yuan Liang said.

"the low utilization rate of coalbed methane equals to waste." Zheng Mingjie said that in 2010, China's coal mine gas emissions equivalent to the calorific value of burning 20 billion cubic meters of natural gas. At that time, China imported 35 billion cubic meters of natural gas due to "gas shortage." The core of

is financing innovation. The dem for funds of

coal bed methane is huge.

in September last year, the general office of the State Council issued opinions on Further Strengthening the drainage utilization of coalbed methane (coal mine gas), pointing out that it is necessary to improve the stard of financial subsidies, strengthen the guidance support of central financial incentive funds, arrange central financial incentive funds to focus on supporting the closure of small coal mines with high gas content coal gas outburst, improve the utilization rate of coalbed methane, so as to promote energy conservation emission reduction 。

in 2008, Guizhou Panjiang coalbed methane development utilization Co., Ltd. (hereinafter referred to as Panjiang coalbed methane) suffered losses in coal-bed methane power generation sector, which was due to the low on grid electricity price the large expenditures on production costs, management expenses taxes. Since then, the state has issued a series of preferential policies in the aspects of power generation price, grid connection, tax finance, the company turned from deficit to profit the next year. Panjiang coalbed methane is a holding enterprise of Panjiang investment holding group, which is a large state-owned coal industrial enterprise in Guizhou Province.

are too dependent on the government may not be beneficial to the commercial utilization of coalbed methane Zheng Mingjie said that at present, most projects still rely on government incentives financial subsidies, the core of CBM utilization is financing innovation.

he said that public funds, including special funds from the Ministry of finance, the national development Reform Commission the Ministry of industry information technology, are only one part of the development utilization of coalbed methane.

"private investment is too small." At present, China lacks climate financing diversified financing channels have not played a role, he said. According to data, in 2011, China's climate financing from banks amounted to 1.9 trillion yuan, while private financing was only more than 30 billion yuan.

on July 9, the reporter learned from the state owned assets supervision Administration Commission of Guizhou Province that in the face of financing difficulties, in the new round of state-owned assets mixed system reform, Panjiang group put forward the scheme of direct financing through property right reform, which will promote the reform listing of Guizhou Panjiang coalbed methane development utilization Co., Ltd. Previously, it has raised funds through the issuance of notes for enterprise development. The third part of

is the support from the world bank, the Asian Development Bank other international organizations. The foreign office's China prosperity Strategy Fund invests 2.8 million pounds a year to China, supporting more than 40 cooperation projects in related fields, including low-carbon, energy green finance. The clean coal center of the International Energy Agency is also funding clean coal projects in Henan Shong. "
