INTEGRATED MONITORING OF GEOLOGICAL ENVIRONMENT IN THE LIMITS OF MINING ALLOTMENT OF BEING CONSTRUCTED TUNNEL
Abstract and keywords
Abstract (English):
Purpose: To consider the example of the implementation of integrated monitoring based on various information collection and analysis on soil environment movements for further prognosis on massif state and timely corrections of construction decisions. To establish sequence and rhythm of monitoring implementation stages for to obtain timely information on soil massif state. To reveal possible ways of statistical processing of observation results for to ensure deformation development prediction reliability. Methods: No-touch registration method for electromagnetic emission, ground penetrating radar method, seismic-acoustics method, geodetic method, strain gauge method, statistical methods. Results: Possibility to embody deformation complex monitoring on certain example has been studied. Possible sequence of monitoring stages with the use of modern methods and technologies has been described. It has been shown that the collection of data on soil massif state from various sources makes it possible to make reliable conclusions on mining operation safety and to verify them by using statistical analysis methods. The results of real observations of deformations in the limits of mining allotment have been considered. Recommendations are given on observation organization during flank process activation. It has been described the possibility of deformation monitoring organization with complex use of various means for measurement such as inclinometric probes, high precision levels, electronic tacheometers, load cells. Geodetic monitoring (geodetic measurements) of deformations during tunnel construction should be carried out. The paper considers the need to project and create geodetic monitoring planned-altitude networks serving as a base to make observations with required accuracy on offset of construction’s structures and objects surrounding the construction. Practical significance: The results can be used in job organization to monitor offsets in excavation outputs, day surface (surrounding buildings) deformations, in the design of observation stations.
