Project summary

The main objective of the project is to solve a local environmental problem relating to the Earth's interior. This will be done by developing a technology of constructing complexes for the protection of the Earth's interior from migrating flows using technical tools of borehole hydromechanization.

Results of the project will have a commercial potential. The project will engage scientists and engineers formerly involved in the development and production of weapons of mass destruction. Therefore, the project's tasks meet the ISTC's goals and objectives.

Technical Approach

As it was demonstrated by the proposers in their preliminary investigations, the solution of project's tasks will result in the development of a new technology of constructing a complex of filtering and anti-filtering curtains. This approach has several advantages over sue existing technologies, as high-pressure thin hydraulic jets, drilling & filling method, mechanical methods based on trench panels, and fixing of the grounds by injections. The main advantages over the alternative methods include the reduced costs and a shorter period of construction, the use of easy to operate and less expensive equipment, control over filtering curtain's stability in any site, and the self-adjustment of the complex based on rock filling by migrating flows. All the above mentioned aspects will allow to improve the state of the Earth's interior and the local environmental situation.

Anticipated Results

Works to be carried out within the framework of the Project encompass the selection of core samples in the region with unfavorable environmental state. The samples will be used for physicomechanical investigations, e.g. the description of rheological features of rocks, determination of hydrodynamic parameters of migrating flows on the electrohydraulic models, development of compounds for laying solution and the selection of materials for filling filtered boreholes, as well as the investigation of geomechanical sheets of thin cavities using equivalent materials.

The project participants have gained an extensive knowledge and experience in this area of activities.
