超大采高综采工作面综合防尘技术及应用

Comprehensive dust prevention technology and application of comprehensive mechanized coal mining face with super large mining height

粉尘是在巷道掘进或生产过程产生的飞逸到环境空气中的固体颗粒,同时粉尘也是煤矿五大自然灾害之一。随着采煤机械设备的不断发展改进,综合机械化采煤工作面的采高设计越来越高,同时产生的粉尘也越来越多,探索超大采高综合机械化采煤工作面防治粉尘,对矿井的安全生产有十分重要的意义。通过神东补连塔煤矿8 m综采工作面综合防尘的实践,总结了超大采高综合防尘的优缺点,探索更有效的综合防尘措施,保障作业人员的职业健康,促进煤矿安全生产。

Dust is a solid particle which escapes to the air in the process of roadway excavation or production.Dust explosion is one of the five natural disasters in coal mine.With the continuous development and improvement of coal mining machinery and equipment,the design of mining height of comprehensive mechanized coal mining face is higher and higher,at the same time,more and more dust is produced.It is of great significance to explore the prevention and control of dust in super large mining height comprehensive mechanized coal mining face for the safety production of mine.Through the comprehensive dust prevention practice of 8 m fully mechanized working face in Bulianta coal mine of Shendong,this paper summarizes the advantages and disadvantages of comprehensive dust prevention of super large mining height,explores more effective comprehensive dust prevention measures,ensures the occupational health of operators,and promotes the safety production of coal mine.
