| Abstract: | The formation of Baoshan mining area in Dangping tungsten mine was complicated with hard and broken rocks in Jiangxi Province. Drilling was very difficult because borehole collapsing, diameter shrinkage, sticking and burying often occurred. According to the characteristics of complex formation and the construction difficulties, a set of pertinent technical measures were summarized in equipment selection, borehole structure, bits selection, washing fluid and wall protection & leakage control. Good effects have been obtained in the field application. |
