摘要 为了提高坚硬岩石巷道的掘进速度和质量 ,研究了准直管磨料射流用于岩石巷道掘进的方案 ,分析了准直管磨料射流装备的结构特点和工作原理。试验研究了准直管结构参数、磨料参数、进给速度对射流切割效果的影响。初步研究表明这一设想基本可行 ,是一种值得探讨的新型掘进方法。 A new-type tunneling system, Collimated Abrasive Water Jet (CAWJ) cutter, is developed to increase the tunneling speed and improve the cutting quality in hard rock. And its characteristics of configuration and operating principle are discussed. The effects of cutting hard rock with various operating parameters on the cutting efficiency of CAWJ are analyzed. Research results show that it is primarily feasible for tunneling hard rock with CAWJ.
