The thermal condition and stability of underground tourist complex workings

Abstract

The article presents the development of measures to ensure the required thermal condition and recommendations for support setting of underground mine workings in the conditions of the cryolithozone, ensuring the stability of the workings and safe living conditions in the galleries of the tourist complex “The Kingdom of permafrost” (TKoP), located on the 5th km of the Vilyuysky tract in Yakutsk. The following research methods were used: field observation of the temperature condition, visual inspection of the slope and underground mining of the tourist complex, the choice of a rational type of support setting, calculation of the parameters of the support, mathematical modeling and numerical calculations of the temperature condition. The main research results are obtained: the results of field observation of the thermal condition of underground mine workings of the tourist complex “The Kingdom of permafrost” in the winter and spring period of operation, the results of visual inspection of the slope, galleries and chambers, and recommendations for ensuring stability and support setting the existing fallout zones are given. The calculation of the temperature condition of the TKoP and the required capacity of refrigeration machines was performed using the Museum CVM software package developed in the Laboratory of Mining Thermophysics of the IGDS SB RAS. To reduce the energy consumption for the production of artificial cold in the summer, it is recommended to carry out annual autumn and spring cooling charges with artificial ventilation. The recommendations for support setting mine workings have been developed.
