Estimation of metrological capabilities of the equipment for measuring the manifestations of rock pressure
Authors:
Abstract
Solving problems of operational monitoring of rock pressure parameters is connected with the necessity of obtaining a large volume of data on the stress-strain state of the rock mass and the support of workings. These data can be obtained promptly only with the use of special measuring apparatus, for example, that developed at the LGI. It makes it possible to receive information from a large number of various sensors located within the entire mine field at considerable distances from each other. As shown by pilot-industrial tests at the Mayak and Kaula-Kotselvaara mines, the effectiveness of such apparatus largely depends on metrological parameters.
