    Abstract:

    This paper analyzes the main problems in gas control and recycling in deep outburst mines in China, and summarizes the development status of gas control, gas extraction, gas utilization and heat damage control. Taking Shoushan No. 1 mine as an example, a closed loop system architecture of gas treatment - gas extraction - gas power generation - centralized refrigeration - heat damage control is proposed to realize safe, efficient and green development of deep outburst mine. The comprehensive gas control technology of "one side and many lanes" in coal seam with single mining height and low permeability outburst in shoushan mode is studied. The combined operation process of gas power generation equipment and refrigeration equipment is analyzed to realize effective treatment of heat damage in deep Wells. The demonstration project of power grid connection and mine cooling in Shoushan No.1 mine was established to realize the unification of comprehensive management and recycling of gas resources, and to form a safe, efficient and green development mode of deep outburst mine, which can provide reference for similar mine development in China.
