Abstract：To improve the dust-isolating effect of rotating air curtain at fully-mechanized working face,based on the de-dusting mechanism of spray,this paper modified the de-dusting efficiency of rotating curtain by air-water combination.The paper makes a comparative research of the de-dusting effect between the improved air-water combined rotating air curtain and the original rotating curtain through the test system and scheme.The resuhs show that the dust-isolating effect of air-water combined rotating air curtain is superior to that of the ordinary air curtain;de-dusting effect of the improved air curtain is higher than that of the ordinary in both respirable dust and total dust under the same condition.The results are consistent with the theoretical results.
