摘要
针对松软煤层空气钻进装备集成性差、工艺流程复杂、操作繁琐等问题,特别配套了ZDY5000RF型钻机及配套装备,结合配套装备的技术参数、性能特点,在祁南煤矿进行了工业性试验。现场应用表明,ZDY5000RF松软煤层钻进专用钻机具备在f值为0.5左右的煤层中钻进200 m深孔的能力,具有集成性好、钻进效率高、除尘效果显著等特点,各项技术指标均达到了设计要求。
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.
