      <abstract xml:lang="ru">
        <p>В условиях горных предприятий канал связи, как правило, является наиболее слабым звеном в системе передачи инфор­мации. Частные нарушения горногеологических и климатиче­ских условий приводят к его повреждениям и, следовательно, потере информации. Поэтому при измерениях в труднодоступ­ных местах и опасных условиях необходимо использовать ка­налы связи, на которые изменения внешних факторов влияли бы минимально (например, рельсы, трубы, заземляющие шины, тролеи или специально проложенные стальные тросы) ...</p>

      <abstract xml:lang="en">
        <p>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)...</p>
