Present situation and development trends in the area of underground nuclear waste storage sites
Šňupárek, Richard ; Kukutsch, Radovan ; Koníček, Petr
A secure solution of nuclear power plants fuel cycle end is undoubtedly a great technical challenge facing all developed countries, using nuclear energy. High demands on safety performance target solutions are enhanced primarily by the requirement to actually "geological" life of the project period, which represents a period of about 100,000 years. Although currently is not implemented yet neither persistent storage, it is interesting to compare the solutions prepared in different countries from different aspects of natural conditions, structures, volume and time schedules or ongoing research programs. The subject paper is based on publicly available information sources, especially from the pu-blications and presentations at scientific conferences in the last 2 years.

Project monitoring the stress-strain state of the rock mass during extraction of coal seam 30 (634) within the test run mining methods corridor - a pillar in the OPJ Mine CSM - Sever. Proposal verify the possibility to use anti-shake prognosis and prevention using mining methods corridor - pillar within pilot operation in seam 30 (634) in OPJ Mine CSM - Sever

On the basis of a contract for No. 850/33/10 and Appendix 1 of this contract , between OKD , as, ČSM and the Institute of Geonics AS CR, v.v.i. we present the following project monitoring stress tension-deformation condition of the rock mass during extraction of coal seam No.30 (634 ) within the test run mining methods corridor - pillar in a protective pillars jam CSM Mine, north location. Monitoring of the stress tension-deformation state of rock mass is a prerequisite for successful verification of a new mining method unapproved hall - pillar and its further use in the Czech part of the Upper Silesian Coal Basin. This mining method is designed on the basis of experiences and practices, which are verified in different natural conditions and depths, and therefore it is necessary for the verification of the conditions of the Czech part of the Upper Silesian Basin on the basis of the proposed geotechnical monitoring. Test operation of the new hall - pillar method will be implemented in the seam No.30 (634 ) in the rock mass included in the category without the risk of shocks.

Design of roadway support in coal mines
Šňupárek, Richard
Design of roadway support in coal mines is mostly based on simple united methods for designating of support loading and for design of support constructions. These methods are based in majority of cases on practical engineering processes with using of empirical knowledge from the area of interest (mine, deposit, stratigrafic unit). In cases with similar conditions it is possible to compare the methods of roadway support design. The contribution deals with comparison of design methods used in Ostrava Karviná coal basin and Ruhr coal basin in Germany.

Verification of the possibility of utilization of rockbolt technology in the Nováky colliery conditions
Koníček, Petr ; Souček, Kamil ; Šňupárek, Richard ; Hrabovský, J.
Deformation of longwall gates are significant mining complication in conditions of mining of thickness brown coal seams. Difficult mining conditions are coped with standard way – reduced steel arch support spacing, wood polygon supports and timber poles etc. Presented contribution introduces the first step to application bolt technology for strengthening of current longwall gate support. In roadway No. 111 114-05 was installed dozen set of glass fibre reinforce plastic grouted rockbolts K60-25 by polyester resin Lokset in conditions of Nováky Colliery. Afterwards it was carried out pull tests of rockbolts, their assessment and it was defined recommendation for rockbolts using in conditions of Nováky Colliery
