摘要
In the deep prospecting drilling construction of Xiaoqinling gold field,SYZX wire-line coring hydro-hammer was adopted to prevent deep drilling inclination,which can improve footage per run and efficiency per hour,and prolong service life of bit in hard brittle formation.The paper summed up the problems often encountered in the application of hydro-hammer.
