| Abstract: | The construction difficulties of drilling program in Daqiao gold mine of Xihe County, and counter- measure technique employed for these difficulties are summarized in this paper. It have been employed diamond drill technique of single power with double pipes and borehole wall protection of polyacrylamide, which is a drilling fluid of non-dispersing and lower solid phase. The construction results verified these countermeasures are effective. |
