| Abstract:Air reverse circulation continuous sampling drilling technology is used for the exploration construction in open-pit mine. The causes of string sticking encountered in drilling is analyzed and the corresponding operation rules are determined in order to prevent sticking accident and by the construted auxiliary holes and milling technology, good results are achieved in sticking accident treatment. |
