Calculation of linear parameters of long lines equivalent to information transmission lines in mining operations

Abstract

In the conditions of mining enterprises, the communication channel is usually the weakest link in the information transmission system. Particular violations of mining and geological and climatic conditions lead to its damage and, consequently, loss of information. Therefore, when measuring in hard-to-reach places and dangerous conditions, it is necessary to use communication channels that would be minimally affected by changes in external factors (for example, rails, pipes, grounding tires, trolleys or specially laid steel cables)...
