In order to improve the dust removal power of the dust removal equipment in the roadway and the working environment of underground coal mine operation,an air-water linkage dust removal system is designed.Based on the actual situation on the site of digging face,the air-water linkage dust removal system is made applicable to the working face,and the key components and installations of the air-water linkage dust removal system and the air-water linkage dust collector,dewatering knuckle and dust suction hood in the system are designed,researched and applied.In practice,when the wind speed exceeds 300 m3/min,the ability to purify the air will reach an excellent level,in which the purification ability of the whole dust can reach 38.7％～55.4％,and for the respiratory dust,the purification ability can reach 31.2％～42.9％,so as to achieve the highly efficient purification and dust removal effect.
