Preliminary Study on Evaluation Method of Dust Suppression Effect in Coal Mine
This paper studies and evaluates the effect of using dust suppressants in underground coal mines by evaluating the thickness of solidified layer,wind erosion rate and spray dust removal efficiency,and provides scientific basis for coal mine enterprises to choose the most effective products.It is found that the appropriate selection and use of dust suppressants can significantly reduce the concentration of underground dust,improve the working environment,and reduce the harm to the health of miners.In addition,the study recommends the use of crust-type dust suppressants,which inhibit dust secondary flight by forming a solidified layer,and capture type dust suppressants,which focus on capturing dust particles in the air.The experimental results show that the selected dust suppressor can effectively improve the dust removal efficiency and has practical application value.
