Abstract: To reduce the dust concentration of heading face, the dry-type dust removal system is introduced to Cuncaota Coal Mine. Aiming at the problems presented in the using process, some measures are taken, such as the position optimization of fan to less dust removal equipment running resistance, determining the proper type of fan by the matching principle of air supply quantity and air suction quantity for dust removal fan, multi duct dust absorption, hanging rail of duct and so on. The comprehensive dedusting efficiency in the heading face field reaches more than 97%, the total dust concentration is below 5.9 mg/m³, and the respiratory dust concentration is below 2.4 mg/m³, which effectively reduces the dust concentration in heading face, improves the health safety of staff and reduces the working intensity.
