Abstract：Double connection triangles method in verticalshaft connection survey is proposed. Compared with the single connection triangle method, this method not only improves the accuracy but also gives a significant increase in check conditions. Threewire connection triangle method and double stations connection triangle method are compared with each other to analyze the application from their advantages and disvantages. Threewire method is often used in spacious shafts because of its good stability, simple operation and conveniences. Double stations method is more timesaving and more convenient to the shaft, but it is often limited by the underground space and circumstances. So the former is more commonly used.
