It was shown that presentations on mechanism of rock and tectonic bursts developed for coal deposits, are not suitable for the conditions of ore deposits. Forms of manifestations of rock and tectonic bursts at ore deposits have been determined by experimental data including the artificial initiation of rock bursts in pillars.
The paper presents the data on the mining-geological conditions for mining and types of stope supports applied at the Karnasurt Mine, the Lovozersky rare-metal deposit. The peculiar feature of mining conditions is the presence of high subhorizontal tectonic stresses in the rock masses, which make the stope roofs more stable, allowing application of non-reinforced types of support.
There are a number of domestic and foreign mineral deposits, the development of which creates large areas of undrained host rocks above the cleaning spaces. There is a serious problem of their possible impact on neighboring mine workings and on surface natural objects and engineering structures. ...
