Application of comprehensive utilization technology of ultra low gas in Xiaozhuang Coal Mine
The comprehensive utilization of coal mine gas is an important means for coal enterprises to achieve the goal of carbon peak and carbon neutrality.Aiming at the shortcomings in the application of large volume discharge and resource uti-lization technology for ultra-low-concentration gas,combined with the current situation of gas extraction and utilization in Xi-aozhuang Coal Mine,we put forward the"thermal storage and oxidation technology",formulated a series of implementation plans,and analyzed the effectiveness of the utilization of ultra-low-concentration(less than 10%)coal mine gas.The practice shows that the remarkable economic and environmental benefits have been achieved after implementation of this technical scheme,providing reference for the utilization of low concentration(8%)of extracted gas.
