Pipelines' studies -- new problem for geophysics

The modern technical civilization creates the advanced network of subterranean communications. From the century's beginning many thousand kilometers of various pipes and cables were stacked in ground on depth up to 5-6 meters. Their large part concentrates in cities. Among these there are communication's lines, electrical power cables, water, oil and gas tubes, heat-conducting, water drain and waste water pipes. Especially large density of the communications achieves at territory of industrial plants. This network of pipes and cables creates artificial (technogenic) medium, which requires the constant control. At installation of pipes and cables their position is reflected in documents, however in time some engineering specification becomes outdated or even lost.
