过去用物理方法采煤,地上、地下都需要大量的人员和设备,投资巨大、安全性差,而且由于采掘技术落后,资源浪费也很惊人。现在研究成功的煤炭地下气化技术,甩掉过去地上、地下所需大量人员和设备,改用地下长通道、大断面、输气加压鼓风控制燃烧以产生可燃气体,并能直接合成甲醇、二甲醚、醋酐等众多化工产品或提取纯氢,使煤炭转型成为新的清洁能源。这种新技术将建井、采煤、气化三大工艺合而为一,具有安全性好、投资省、见效快、效益高、资源浪费小等优点,从而使吨煤产值大幅度增加。
In the past, coal mining was performed by physical methods. A large number of people and equipment were required on the ground and underground. The investment was huge and the safety was poor. Moreover, due to the backward mining technology, the waste of resources was also surprising. Now we have successfully researched the underground coal gasification technology and eliminated the large number of people and equipment required in the past on the ground and underground. We switched to underground long tunnels, large sections, and gas transmission to control the combustion with pressurized air blast to produce combustible gases and to directly synthesize methanol. , Dimethyl ether, acetic anhydride and many other chemical products or extraction of pure hydrogen, so that the transformation of coal into a new clean energy. This new technology combines the three major processes of well construction, coal mining, and gasification into one, and has the advantages of good safety, low investment, rapidity, high efficiency, and small waste of resources, resulting in a significant increase in the output value of tons of coal.
