Calculation of the linear parameters of long lines equivalent to information transmission lines in mining workings
Abstract
In the conditions of mining enterprises, the communication channel is usually the weakest link in the information transmission system. Frequent violations of mining, 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 busbars, trolley wires or specially laid steel cables). ю..
