ABSTRACT
The article describes the complex technology applied for the compaction of collapsing soils such as mixed: watering, deep explosions, and soil columns in the industrial area in south Russia. The presented method on the example of its use is attractive because of low cost, low consumption of materials, and interesting use a local materials to change subsoil properties. As a result a semi homogeneous structure of ground with a thickness more than 20m was achieved. Monitoring of the neighbouring buildings, according to previous experience, did not show the negative effects of the micro explosions even at the distance of 15m from the source. This is due to the use of precisely controlled energy of underground explosion as a function of depth and density of material. The monitoring was conducted continuously after compaction and it confirms the effect of strengthening stability.
