Research on water injection pre-wetting of raw rock in Xinjiang Dananhu No.2 Mine
摘要
Abstract
Taking the raw rock working face of Xinjiang Dananhu No.2 Mine as the research object,the article adopts FLUENT 19.2 software to establish the three-dimensional flow field model of water injection and pre-wetting in the open-pit coal mine working face,and analyzes the effects of water injection composition,water injection flow rate and water injection pressure on the water injection and pre-wetting effect in the open-pit coal mine working face,and designs the validation test for raw rock dust the water injection and pre-wetting.The results show that the effect of dust suppressant solution water injection pre-wetting is better than that of water injection pre-wetting only;the optimal water injection flow rate is 6 m/s and the optimal water injection pressure is 4 MPa,respectively;and the results of water injection pre-wetting validation test of the raw rock dust coincide with the numerical simulation results.The study provides a theoretical basis for the realization of dust suppression by water injection and pre-wetting of raw rock in the working face of open-pit coal mines.关键词
