Xi ′an Research Institute, China Coal Technology and Engineering Group Corp, Xi ′an 710077, China; 2. Huaibei Mining Group Co., Ltd , Suzhou 234115, China) Abstract: Air drilling equipment has several problems including low level of integration, complex drilling process and tedious operation. In order to solve these problems, technical parameters of ZDY5000RF drill rig and auxiliary equipment are introduced. Field experiment was implemented in Qinan Coal Mine and showed that ZDT5000RF rig has the capacity to drill 200m deep holes in soft seams with f around 0.5. Application also indicated that the rig has significant advantages such as high level integration remarkable dust extraction capacity and high drilling effi- ciency. All the technical indicators have reached the design requirements. Key words: soft coal seam; drill rig; combined drilling; dust extraction
