本文通过对综掘工作面湿式通风除尘系统原理的研究，经过综合论证，利用湿式除尘的原理，根据井下巷道断面、综掘机整体结构，经过优化设计，确定了湿式通风除尘系统结构，该系统设计合理、技术先进，实现了除尘器、吸尘装置和管道等部件能随掘进机跟机行走，减轻了工人的劳动强度，并在压入式通风风筒上，使用了带风门的附壁风筒，提高了收尘效率。在同样条件下，没有使用该系统前粉尘最高浓度达到310mg／m3，使用后最高浓度只有49mg／m3，降尘率达到了84．2％，降尘效果明显，改善了工人的作业环境，提高了安全保障能力，为促进综掘机械化的发展发挥了积极作用，产生了较大的经济效益和社会效益。
本文通過對綜掘工作麵濕式通風除塵繫統原理的研究，經過綜閤論證，利用濕式除塵的原理，根據井下巷道斷麵、綜掘機整體結構，經過優化設計，確定瞭濕式通風除塵繫統結構，該繫統設計閤理、技術先進，實現瞭除塵器、吸塵裝置和管道等部件能隨掘進機跟機行走，減輕瞭工人的勞動彊度，併在壓入式通風風筒上，使用瞭帶風門的附壁風筒，提高瞭收塵效率。在同樣條件下，沒有使用該繫統前粉塵最高濃度達到310mg／m3，使用後最高濃度隻有49mg／m3，降塵率達到瞭84．2％，降塵效果明顯，改善瞭工人的作業環境，提高瞭安全保障能力，為促進綜掘機械化的髮展髮揮瞭積極作用，產生瞭較大的經濟效益和社會效益。

Based on the comprehensive excavation face wet ventilation and dust removal system principle study, after a comprehensive feasibility studies, the use of the principle of wet dust, according to the underground tunnel cross - section, the overall structure of integrated excavators, optimized design, ventilation and wet dust removal system to determine the structure, The system design, advanced technology, to achieve a dust collector, vacuum devices and piping and other components can walk with the boring machine with the machine, reducing the labor intensity, and into the ventilation duct in the pressure on the throttle with the use of The mural hairdryer, improved dust collection efficiency. Under the same conditions, do not use the system before the maximum dust concentration 310mg/m3 , with the highest concentration only after 49 mg/m3, the rate reached 84. 2% dust, dust effect is obvious, to improve the working environment of workers, improved safety ability to promote the development of integrated mechanized excavation has played an active role in creating a greater economic and social benefits.
