Intelligent Ash and Slag Removal Technology and Equipment for Open-pit Rotary Drill

针对钻机钻后人工清理岩渣存在的工作量大、劳动强度大、粉尘危害大等问题,本文提出了六爪式、独立小车式、倒渣桶式三种清灰除渣技术,分别论述了三种方式的总体技术方案、系统组成、工作原理与优缺点,研发了相关设备,进行了实验室试验与现场实验,通过优化对比最终采用倒渣桶方案。经现场使用证明效果良好,对提高钻孔作业的智能化技术水平与工作效率,具有重要意义。

In response to the problems of heavy workload,high labor intensity,and high dust hazard in manual cleaning of rock debris after drilling,this article proposes three ash and slag removal schemes:six claw type,independent trolley type,and slag bucket type.The overall technical scheme,system composition,working principle,advantages and disadvantages of these three methods are discussed,and relevant equipment is developed.Laboratory and on-site experiments are conducted,By optimizing and comparing,the final solution is to use a slag pouring bucket.The on-site use has shown good results,which is of great significance for improving the intelligent technical level and work efficiency of drilling operations.
