背景:中国政府高度重视煤矿安全Background: Central government’s committment

2007年9月，温家宝接见煤炭工业劳模时强调：－－煤炭是我国能源主体，有力地支撑了国民经济发展－－要把煤矿安全作为政府和企业的重要责职，要作为头等大事来抓

2005年，国务院决定：－－开展煤矿瓦斯治理攻坚战

Premier Wen Jiabao:－Coal strongly supports economic growth as main energy source in China－Coal safety is top priority of government

and coal companies

State Council decided:－Controlling of coal mine gas for mine safety

1. 中国煤层气资源CBM/CMM resources in China

36.8 trillion m3 of CBM/CMM resources are contained in coal fields in depth of above 2000m, as much as the total amount of conventional natural gas resources in China (35 trillion m3).CBM reserves in china are only less than Russian and Canada, which lies the third position in the word.

中国煤层气资源非常丰富，根据

国土资源部2008年8月最新的煤

层气资源评价，全国埋深2000米

以浅煤层气地质资源量为36.8万

亿m³，相当于国内目前常规天然

瓦斯利用率仅有30%左右，利用潜力很大，利用率偏低，其

原因：

•①我国大部分煤矿区地质条件复杂，渗透率低，多采用卸压抽采

进行瓦斯抽采，从而导致瓦斯抽采浓度偏低；

•② 低浓度瓦斯易爆炸，难利用，经济效益差；

•③ 政策受限制。

低浓度瓦斯利用是提高瓦斯利用率的关键

The CMM utilization efficiency is 0nly 30%, which lies low level and have great potential. What cause the result as fellow: ① most of our coal mining area geological conditions is complex and low permeability The low concentration gas were drained by the way of pressure relief drainage method ② LCG is easy to explose, difficult to use, low economic efficiency; ③ policy restrictions. LCG utilization is the key to increase the CMM efficiency .

煤层气液化地面煤层气(CBM)液化

地面煤层气(CBM)浓度一般在95%以上，经脱碳、脱硫、脱汞和脱水后，可

直接加压、深冷液化成LCBM。

矿井瓦斯(CMM)液化

矿井瓦斯（CMM）一般浓度较低且含有氧气，若直接加压液化会引起爆

炸。采用深冷精馏的方法，把含氧矿井瓦斯的分离和液化在低温的条件下同

步完成，提纯制得液化煤层气。该方法可把浓度为35%-50%矿井瓦斯的提

纯液化为浓度为99.8%的LNG。

CBM/CMM LiquefactionCBM LiquefactionConcentration of CBM is usually over 95%. After decarburization, desulfurization, demercuration and dehydration of CBM, CBM can directly be turned into LCBM with high pressure and low temperature.CMM LiquefactionIf directly pressured and liquefied, CMM with low methane content and oxygen can cause explosion. By cryogenic rectification, separation and liquefaction of CMM can be finished together at low temperature. By this technology, CMM with 35%-50% methane can been purified, liquefied and turned into LNG with 99.8% methane .

（1）中国煤层气资源十分丰富，随着国家和煤矿企业对煤矿安全的日益重视和出台相关鼓励政策，煤层气抽采量和利用量都有较大幅度增长;

（2）低浓度瓦斯输送和利用安全生产系列标准的颁布和《煤矿安全规程》的修订，对提高低浓度瓦斯的利用率，促进节能减排，必将产生积极的推动作用;

（3）煤矿加大煤层气抽采量，以及低浓度瓦斯利用和通风瓦斯利用新技术的应用，提供了新的投资机会。

（4）建议国家研究制定更加有力的优惠政策，鼓励企业扩大煤层气利用规模。

6.结论与建议6.Conclusions

（1） China has abundant CMM/CBM resources and has made great progress in CBM/CMM development and utilization with concouraging policies.

（2） The series of technical standards forlow concentration gas transmission and safe utilization have been issued, which will result in increasing utilization of coal mine methane.

（3） Increasement of methane recovery and application of new technologies for utilization of CMM with low methane concentration and VAM provides great opportunities for

investment.（4）It is suggested the central government should working out further incentives to encourage enterprises

to utilize more methane recovered from active coal mines and virgin coal seams.
