ABSTRACT=Coal measure energy production and reservoir space utilization is not only important for energy security but can also assist in achieving carbon neutrality. Coal measure energy production and reservoir utilization are therefore of scientific significance. This study focuses on the security of coal supply by discussing the possible technical approaches of combining low-carbon mining of coal measure resources and coal reservoir space utilization. Our study found that 1) the integrated of Underground Coal Gasification and Carbon Capture and Sequestration (UCG-CCS) is an effective technology to improve energy efficiency and achieve the carbon neutral target in China; 2) CO2 enhanced coalbed methane (CO2-ECBM) recovery is an important way to reduce CO2 emissions during coalbed methane recovery; and 3) the integrated technology of solid Waste Filling(WF), Coal Bioconversion(CB), Gas Production (GP) and CO2 Capture and Sequestration(CCS) in the coal goafs and the abandoned coal mines can improve the energy production efficiency and reservoir space utilization, and reduce geological disasters during to surface subsidence. These integrated technologies will become ever more important approaches for coal measure energy production and efficient reservoir space utilization as they will provide scientific theory and technical support achieve carbon neutrality.
