| Abstract:According to the climate characteristics of Hulun Lake in Inner Mongolia, system of icy lake drilling platform was designed for assuring the work safety and implementing of scientific icy lake drilling in winter. Considering the strata characteristics of Hulun Lake, new piston sampling drilling tool and press-fitting sampling drilling tool were developed. The practice proved that the result of sampling is satisfying with the coring rate of 100%. |
