| Abstract: | To the problem of serious dust pollution during the process of non-circulating drilling in coal seam,dispersity of dust and hardness of coal in C13 and 10 coal seam of Xinzhuangzi mine were measured respectively in the process,dust concentration distribution of the two coal seams were analyzed and compared in the process of drilling under wind velocity of 3 m/s.And aiming at C13 coal seam,distribution situations of dust concentration were measured under wind velocity of 1.5 m/s,2.3 m/s and 3 m/s.According t... |
