摘要
以美国绍尔背包式钻机为例,针对背包式钻机在工程应用中存在的钻进深度不够、钻压水压不稳定、岩样扰动严重和发动机熄火等问题进行分析以及对解决方案进行探讨,并针对使用情况对背包式钻机提出了改进意见,对使用前景进行了展望。
With the case of Shaw knapsack type drilling machine of US, the analysis is made on the problems in engineering application, the insufficient drilling depth, instability of bit and water pressure, serious sample disturbance and engine stall, which are discussed for solutions. In view of the usage situation, the improvement suggestions are put forward.
