摘要
为响应“双碳”战略要求、推动煤炭资源高效利用及封存资源回收,基于煤炭地下气化技术日趋成熟的背景,分析了重庆地区现有煤炭资源开展地下气化利用的可行性。文章选取重庆南桐矿区典型煤矿作为研究对象,从煤种与煤质、煤层赋存条件、地质条件、水文条件、气化关键技术等多个核心维度,开展煤炭地下气化利用可行性分析。重庆南桐矿区典型煤矿在煤种煤质、煤层赋存、地质、水文及气化关键技术等维度均满足要求,适合开展煤炭地下气化实践,且可实现该矿区封存煤炭资源的高效利用。重庆南桐矿区典型煤矿具备开展煤炭地下气化的可行性,该技术应用不仅能高效回收当地封存煤炭资源,也为重庆地区煤炭资源的高效利用提供了技术支撑。
In order to respond to the requirements of the"dual carbon"strategy and promote the efficient utilization of coal resources and the recovery of stored resources,based on the background of the increasing maturity of coal underground gasification technology,the feasibility of underground gasification utilization of existing coal resources in Chongqing is analyzed.In this paper,the feasibility analysis of underground gasification utilization of coal is carried out from multiple core dimensions such as coal type and coal quality,coal seam occurrence conditions,geological conditions,hydrological conditions,and key gasification technologies.Typical coal mines in Chongqing Nantong mining area meet the requirements in terms of coal quality,coal seam occurrence,geology,hydrology and key gasification technologies,which are suitable for underground coal gasification practice and can realize the efficient utilization of stored coal resources in the mining area.The application of this technology can not only efficiently recover local stored coal resources,but also provide support for the efficient utilization of coal resources in Chongqing.
