Abstract

Abstract:

In order to control the large amount of dust produced in the construction process of gas drainage dry drilling, Based on the characteristics of high proportion of respirable dust produced by drilling in broken soft coal seam, A new technology of dry orifice dust removal is put forward, Firstly, the cyclone dust removal technology is used for primary dust removal, Then through the bag dust removal technology to further filter purification, In order to achieve efficient dust removal effect. The structural parameters of the dust removal device are studied, And according to the resistance of cyclone dust removal and bag dust removal, Optimize the power of dust removal device. Field test in broken soft coal seam drilling, Results showed: The total dust removal efficiency of the dry orifice dust removal device is more than 98 %, The dust removal efficiency of respirable dust is more than 96 %, It can effectively solve the dust pollution in the drilling process of broken soft coal seam.
