| Abstract: | The geological structure is complex in Jiakui coalfield with fractured rocks,loose cementation,frequent formations changing and fault fracture zone,so there are the problems such as many downhole accidents,low coring rate and low drilling efficiency.By the wire-line coring hydro-hammer technology,these technical difficulties were solved with less auxiliary time,improved drilling efficiency and coring rate and the borehole quality was ensured. |
