    摘要:

    分析了我国深部突出矿井在瓦斯治理与循环利用中存在的主要问题,总结了瓦斯治理、瓦斯抽采、瓦斯利用及热害治理方面的发展现状。以首山一矿为例,提出了瓦斯治理-瓦斯抽采-瓦斯发电-集中制冷-热害治理的闭环系统构架,以实现深部突出矿井的安全、高效、绿色开发。研究了首山模式下大采高单一低透突出煤层“一面多巷”瓦斯综合治理技术,研发了分源网络化瓦斯立体抽采技术与动态调控技术,实现了瓦斯治理与抽采的高效协作;分析了瓦斯发电设备与制冷设备联合运行过程,实现了深井热害的有效治理。建立了首山一矿发电并网示范工程与矿井降温示范工程,实现了瓦斯资源综合治理与循环利用的统一,形成了深部突出矿井的安全、高效、绿色开发模式,可为国内类似矿井开发提供借鉴意义。

    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.
