摘要
Abstract
With the continuous development of the comprehensively mechanized mining process and the improvement of mechanization in coal mines,the dust production in the comprehensive mining working face increases significantly,which poses a serious threat to the health and production safety of underground workers.In order to reduce the dust in the compre-hensive mining face,a combination of numerical simulation and on-site measurement is used to propose an air curtain dust re-duction technology for the comprehensive mining face,which is tested in the 4101 comprehensive mining face on the 3# coal of Fujiayan Coal Mine.The results of practical application show that:under the action of high-speed airflow field generated by the outlet of 2 air turbines,a triangular air curtain is formed between coal mining machine and roadway,which can effectively prevent dust from entering the driver's working area;the dust concentration in the driver's working area of the coal mining machine is more than 2 000 mg/m3 before applying the dust management technology,but after applying the dust management technology,the dust concentration in the driver's working area of the coal mining machine is reduced to 300 mg/m3,and the dust concentration in the driver's working area of the coal mining machine is reduced to 300 mg/m3,which is effectively blocking and reducing dust in the coal mining process,and improving the underground working environment.关键词
