基于压缩空气蓄能技术的煤矿废弃巷道再利用研究

Research on Reuse of Abandoned Roadway in Coal Mine Based on the Compressed Air Energy Storage Technology

对利用煤矿废弃巷道作为压缩空气蓄能电站的储气室进行了研究。以徐州权台煤矿为例进行了分析,结果表明:将煤矿废弃巷道、压缩空气蓄能技术与峰谷电价差三者有机结合起来,在实现煤矿废弃巷道二次利用的同时,既能对3000 MW容量的电网系统进行调峰带来巨大的社会效益,还能获得每小时22.52万元利润的巨大经济效益,且项目的投资回收期为8.5 a,项目安全率为88.28%,充分证明了将煤矿废弃巷道与压缩空气蓄能技术相结合在技术经济上完全可行。

In this paper,the reuse of abandoned roadway in coal mine as the compressed air storage of compressed air energy stor- age （CAES） power station was studied. And taking Xuzhou Quantai coal mine as an example,a study on CAES is made.The results show that combining abandoned roadway in coal mine, CAES teehnology and the price difference between peak and val- ley electricity together organically, not only the secondary utiliza- tion of abandoned roadway in coal mine can be realized, but also a enormous social benefits brought by peak load regulation of 3000 MW power system can be achieved as well as a huge eco- nomic profits of 225,200 RMB/hour can be obtained, the invest- ment recovery time of the project is 8.5 years,the safety rate of the project is 88.28%.The study proved that the combination of abandoned roadway in coal mine and CAES technology is feasi- bility in technique and economy.
