摘　　要：对煤矿井筒防冻清洁技术进行分析,总结各种技术适用范围。从技术特点出发,结合减碳效果提出井筒防冻清洁技术选择注意事项:应合理降低井筒防冻负荷,根据实际情况选择瓦斯蓄热氧化、余热利用、热泵技术等,可辅以储热或电加热技术,以提高井筒防冻热能利用效率,减少能源消耗和碳排放。并探讨未来井筒防冻技术可能发展方向。Analyzed and summarized the scope of application about anti-freezing and cleaning technology of coal mine shaft.Combined the technical characteristics and reduced carbon emissions,put forward the precautions for the selection of shaft antifreeze technology,which should reasonably reduce the shaft antifreeze load,then select regenerative thermal oxdizer,waste heat utilization or heat pump technology according to the actual situation,and can be supplemented by heat storage or electric heating technology to improve the energy utilization efficiency and reduce carbon emissions.The possible development direction of shaft antifreeze technology in the future was also discussed.
