近年来，随着矿井开采机械化、自动化、智能化水平日益提高，作业环境粉尘污染日益严重。为了进一步提高矿井清洁化生产水平，推动煤矿安全保障能力和职业健康水平，分析了我国煤矿粉尘防治的研究现状，总结了20年来粉尘防治理论及技术取得的成果，并提出了未来发展方向。全面阐述了现有的防尘基础理论，主要包括：粉尘弥散污染规律、粉尘微观润湿理论、尘雾凝并湿式除尘理论、湿式喷射混凝土除尘理论。基于上述理论，国内高校、科研院所研发了综采工作面局部雾化封闭与空气幕隔离、综掘工作面风雾双幕协同增效、煤层注水强渗-增润、矿山湿（潮）喷作业系统、高效环保抑尘剂等不同尘源控除尘技术工艺。同时针对现有研究的不足，在智能化防尘、煤层注水减尘、采掘作业环境降尘、抑尘材料等4个方面给出了下步研究展望。研究与实践表明，我国煤矿已经初步形成了粉尘防治的理论和技术体系，未来要以智能化防尘为抓手,实现粉尘高精度传感—输—评估预警，开发集雾化除尘、干式、干湿混合式、小型化、吸风量大等于一体的组合式除尘器,实现综掘工作面、综采工作面等广域复杂空间微细粉尘高效通风控除尘技术与装备体系；同时，在低渗煤层水力强渗-增润技术、智能化防尘机器人、化学抑尘等技术与装备方面实现突破。以此来实现矿山粉尘的分源高效治理，提升矿井的清洁化生产水平。

In recent years， with the increasing level of mechanization， automation and intelligence in mining， dust pollution in the working environment is becoming more and more serious.In order to further improve the clean production level of coal mines， promote the safety guarantee ability and occupational health level of coal mines， this paper analyzes the research status of dust control in China， summarizes the achievements of dust control theory and technology in the past 20 years， and puts forward the future development direction.In this paper， the existing basic theories of dust control are expounded， including dust dispersion pollution law， dust micro wetting theory， dust condensation and wet dedusting theory， wet shotcrete dedusting theory.Based on the above theory， domestic universities and scientific research institutes have developed dust control and dedusting technology of different dust sources， such as local atomization closure and air curtain isolation of comprehensive mining face， wind fog double curtain synergistic effect of comprehensive mining face， coal seam water injection strong infiltration and moistening， mine wet (tide) spray operation system， high-efficiency environmental protection dust suppressor， etc.At the same time， in view of the shortcomings of the existing research， the next research prospects are given in four aspects:intelligent dust prevention， coal seam water injection dust reduction， mining environment dust reduction， dust suppression materials.Research and practice show that China’s coal mines have initially formed a theoretical and technical system of dust prevention and control.In the future， it is necessary to take intelligent dust prevention as a starting point， realize high-precision dust sensing transmission evaluation and early warning， and develop a combined dust remover integrating atomization， dry-type， dry wet mixed type， miniaturization and large air suction， At the same time， the technology and equipment system of high-efficiency ventilation and dust control of fine dust in wide area complex space such as comprehensive mining face and comprehensive mining face are realized.At the same time， the technology and equipment system of hydraulic strong permeability and moistening technology in low permeability coal seam of mine， intelligent shotcrete dust-proof robot and dust suppression material are also achieved.In this way， the mine dust can be effectively controlled by different sources， and the cleaner production level of the mine can be improved.
