Study and Application of Secondary Dust Fall Technology with Shearer's Negative Pressure in Fully Mechanized Sublevel Caving Face

综放工作面的尘源中采煤机的产尘约占总尘量的一半左右 ,本文通过兴隆庄煤矿“综放工作面采煤机负压二次降尘技术”的现场研究及应用 ,比较有效地解决了采煤机的产尘问题 。

Dust produced by shearer cutting amounts to about half of total dust content from all dust sources in fully mechanized sub level caving face.This paper adopts field study and application of 'secondary dust fall technology with shearer's negative pressure in fully mechanized sub level caving face'in Xinglongzhuang Coalmine,The problem of dust produced by shearer cutting is solved effectively and the working environment is improved obviously.
