Abstract
Against the backdrop of sustained global energy demand growth and increasing environmental protection pressure, coalbed methane, as a clean and efficient energy resource, has received widespread attention for its development and utilization. However, the process of coalbed methane mining faces many technical challenges, such as poor reservoir permeability, the contradiction between water resource protection and mining efficiency, mining challenges under complex geological conditions, and the impact of mining activities on the ecological environment. These problems seriously constrain the effective development and utilization of coalbed methane resources. This article focuses on the technical difficulties and solutions of coalbed methane extraction. Firstly, it outlines the geological basis, basic principles of extraction, and classification of extraction techniques for coalbed methane, laying a theoretical foundation for subsequent analysis. Subsequently, the four major technical challenges faced in the process of coalbed methane mining were analyzed in depth: low mining efficiency caused by poor reservoir permeability, conflict between water resource protection and mining efficiency, difficulty in mining in areas with complex geological conditions, and the impact and assessment of mining activities on the ecological environment. In response to these challenges, this article proposes corresponding solutions, including the application of enhanced mining technology, water resource protection and water-saving mining strategies, innovation in mining technology under complex geological conditions, and the promotion and implementation of environmentally friendly mining technology. These solutions aim to improve the efficiency of coalbed methane mining, reduce mining costs, protect water resources and ecological environment, and promote the development of the coalbed methane industry towards a greener, more efficient, and sustainable direction.
