Study on Side Roll Damper in Coal Mine and Its Influence on Air Volume in Roadway
Taking side roll damper in Shanxi A Mine as an example,based on the influence of side roll damper on roadway air volume under different working conditions,an analysis method was introduced.In this method,parameters such as the size and material characteristics of the damper were input into ANSYS software(Finite Element Analysis software),the finite element model of the damper was automatically constructed by the software,and then different wind speed of the damper was designed according to the actual situation of underground operation in the coal mine,on this basis,the changes of air volume and resistance in the roadway under different working conditions were simulated respectively and analyzed to facilitate accurate adjustment of the damper.Through the verification,the method has certain application value.
