The relevant importance of the issue of enhancing the efficiency of orientation and connection surveys and height bench mark transfers

Abstract

Transferring height bench marks into a mine's underground workings and orientation-connection surveys are specific types of mine surveying that impact the accuracy of the surveying support for underground mining and it is therefore necessary to take into account the particular importance of their performance. The increasing depth of mining makes rock bursts and other cata-clysms more likely, so the issue of enhancing the accuracy of determining the height bench marks used to solve a wide range of problems in underground mining is becoming more relevant.
