Abstract.

The work is aimed at improving mechanisms for controlling the stress-strain state of large underground mine workings with a chamber-pillar system of mining. The aim of the work is the development and implementation of methods and special equipment for monitoring and diagnosing the state of the roof of mine workings of non-metallic mineral deposits, which ensure long-term operation of large section chambers. Using the example of the gypsum mine of the Siniat ALC in Bakhmut, Ukraine, the stages of development of deformation processes in the roof of highly loaded workings are shown. The accelerated development of deformations in zones of geological disturbances is established. The necessity of organizing integrated control of the roof of mine workings as the weakest link in the underground geomechanical system is substantiated. The task of improving the safety of mining at the mine was accomplished by organizing and conducting geomechanical monitoring of the state of the roof of mine workings. Monitoring involves the provision of operational monitoring of the situation in a particular area of the mine field. This makes it possible to implement organizational and technical solutions that exclude the occurrence of an emergency and reduce the damage from exposure to incorrigible natural factors. To solve diagnostic problems of varying complexity, three levels of monitoring are recommended. The effectiveness of the integrated use of visual observations, instrumental measurements and vibro-acoustic diagnostics of the state of the roof is established. Examples of long-term monitoring of dangerous sections of roofing workings are given. Improving the monitoring of the condition of the roof of underground mine workings with a chamber-and-pillar system for the development of non-metallic mineral deposits allows increasing the level of safety in the mine and preserving the environment. The development does not contradict the requirements of national regulatory documents in the field of labor protection. Monitoring is technically and economically adapted to the capabilities of the production structure of the enterprise. Monitoring experience can also be recommended for mines producing anhydrite, limestone and marble.

Keywords: monitoring, diagnostics, big section chambers, deformation of the roof, gypsum mine.
