Analytical method for calculating the coefficient of technological soil sampling in the organization of mining and construction works with the use of mechanized tunneling

The organization of mining operations is characterized by a significant discrepancy between the calculated and actual precipitation of buildings and structures, especially during shield tunneling of subway tunnels. The article gives the reasons for this discrepancy. The underground construction method is characterized by the greatest precipitation, when modeling deformations of the soil massif in the case of soil development in a closed way. The most important design parameter is the search of the soil, its value is equal to the ratio of the area of the soil removed during sinking, located within the contour of the workings, to the area of its cross-section. The reasons for the search of soil in the case of tunneling in an underground way, leading to technological deformations of the surface, are listed. The research carried out in this area, the assumptions made are described and the final results of the analysis are given in the form of a dependence of the soil sampling coefficient on the shield diameter for various types of soil. All the studies were carried out on the example of the sinking of a specific construction object — a double-track distillation tunnel under the station “Pechatniky” of the LublinDmitrov line of the Moscow metro, conducted in difficult mining and geological conditions under a complex of underground structures. The comparability of the obtained values with the results of foreign research in this direction is noted. It is concluded that the organization of mining operations with the use of mechanized shield sinking should be based on the results of model studies of the coefficient of technological soil sampling, depending on the diameter of the shield, the type of soil (clay, loam, sandy loam, sand) and take into account the data of geotechnical monitoring at metro facilities. Only with this approach can precipitation of the Earth’s surface be minimized.

Keywords: geotechnical monitoring, clay, mining operations, soil sampling, sand, calculated precipitation, loam, sandy loam, subway tunnel, actual precipitation, shield method of sinking.
