摘要

经过系统的理论分析计算和多次试验

采用最新螺旋面钻头设计方法

以完善的制造工艺

利用合金钢和高速钢提高刚性和强度

研制了能满足高寒冷地区破冻煤层取煤样的螺旋钻头。该钻头能实现 - 30℃以下冻煤层的采样

Abstract

Through systematic theoritical analysis and calculation

as well as test of many times

an auger type drill bit for destroying frozen-layer to take coal sample in highly cold region has been developed at last by adopting design method of the newest auger-surface drill bit

combining with perfect manufacture technology

and using alloy steel and high-speed steel to enhance rigidity and solidity. The developed drill bit can be satisfactorily used to take sample from frozen coal layer under temperature of below -30℃?
