Tests and Researches of the Auto Anti-Jamming System for the Hydraulic Mining Jumbo
The anti-jamming control system used on the modern hydraulic mining jumbo plays an impostant role in the drilling operations.The enhance of its technical reliability and stability of this system can effectively reduce the frequency of rod jamming during the operation of the hydraulic mining jumbo and maintain the high drilling efficiency of the jumbo.The paper provides a overview of several anti-jamming system used home and abroad.Based on the comparison and analysis,a anti-jamming system for the mining jumbo was proposed,which underwent lab tests and field tests in Xiaoguan Village Iron Mine of Luzhong Mining Co.,Ltd.The results from field tests proved the effectiveness of this anti-jamming system.
