| description | The article discusses the features of technological solutions in the development of chromite deposits at great depths in difficult mining and geological conditions. For a system with self-destruction of ore, as well as for other similar systems, the weakest point in mining is the design of the block bottom, especially for the lower horizons, where the geomechanical situation deteriorates significantly, it becomes necessary to use more powerful supports or to erect artificial bottoms that can withstand acting loads exceeding the bearing capacity of metal supports of various modifications. The most promising solution in the conditions of development of fractured massifs is the geotechnology of creating an man-made bottom at the zone of extraction and delivery of ore mass, in the areas of conjugation overstrett and interstrett pillars, reinforced with multi-support reinforced concrete platforms, as a bearing structural element of the mining system with self-destruction of ore, which can withstand extremely high rock pressure. The article presents the results of calculating the strength of an artificial bottom in a system with selfdestruction of ore using numerical 3D modeling. |
