Abstract: In view of the characteristics of fast driving speed,equipment concentration and large dust production in the rapid driving face of coal mine,taking the rapid driving face of 122107 auxiliary roadway in Caojiatan Coal Mine as the research object,the characteristics of dust production in the rapid driving face were analyzed in detail,and the comprehensive dustproof technology of “spray dust suppression+airborne ventilation dust removal” of the rapid driving face was carried out. According to the dust production characteristics of fast driving face and the shape characteristics of the anchoring all-in-one machine,four kinds of spray devices close to cutting drum and an airborne dust removal device were designed,and the on-site industrial test was carried out. The results show that with the application of comprehensive dustproof reduction technology in the rapid driving face,dust falls above 90. 69%,which can greatly improve the dust pollution of the rapid driving face.
