The article devotes to investigations the caves Heetey - natural monument Trans-Baikal Territory, in connection with the problem of their preservation during the blasting development of the nearby located Ust'-Borzinsky limestone deposits. Limestone processing is planned to open by a career with 5 ledges height of 15 m each. The characteristics of natural conditions, geological, and hydrogeological properties of permafrost enclosing rock massif, provides information about the shape, location and characteristics of ice cover, which affects on the dynamic stability of the cave and its elements. The analysis of the results of experimental studies of dynamic stability of karst cave Heetey to the effects of explosions in the development of the open method of Ust'-Borzinsky limestone deposits is presented. The main purpose of engineering and seismic measurements of vibrations of the rock mass enclosing Heetey cave was to study the amplitude and frequency content of vibrations to assess the seismic effect of explosions carried out in the near quarry with limestone mining.
