FJD9型伞形钻架是在较大直径的立井掘进中,钻凿较深炮眼的凿岩设备,是在FJD6型伞形钻架的基础上发展起来的系列产品。 机样在淮南潘集矿区试验,于1982年7月在淮南通过技术鉴定。到1982年6月底,用该机共掘进立井262.9米,累计炮眼深度为32225.8米,该井筒在3～6月份连续4个月成井40米/月以上,6月份成井54.3米,钻眼效率为183.6米/台时,折合工效为16.7米/工时。
FJD9-type umbrella-shaped drilling rig is a series of products developed on the basis of the FJD6-type umbrella-shaped drilling frame, which is a drilling device for drilling a deeper blasthole in a larger diameter shaft boring. Machine samples in Huainan Panji mining test, in July 1982 in Huainan passed the technical appraisal. By the end of June 1982, a total of 262.9 meters of shafts had been drilled with the aircraft to accumulate a total blasthole depth of 32225.8 meters. The wellbore was completed for 40 meters / month for 4 months from March to June and 54.3 meters in June. The drilling efficiency was 183.6 meters / Taiwan, equivalent to 16.7 meters / working hours.
