This report covers the first six months of a three-year research project and addresses a range of topic areas linked by the theme of advancing mining support systems to enhance the control of highly stressed ground. A description of the state of the art of these areas includes a general survey of the gateroads and face salvage, rock bolting, laboratory testing of support and rock properties, support behaviour monitoring, methods of rock mass characterization. Methodology of gateroad support design and numerical modelling of geotechnical situations in mining including one-at-a-time analysis (OAAT) and Monte Carlo analysis is presented. Final part described the support managements systems for gateroads and risk reduction system for face salvages. Research part comprised data collection and information relating to the current experience of project partners on gateroad support systems applied at depths below 1000m. Analysis of current UK and European salvage practices and support and the use of the Coal Mine Roof Rating and Reinforcement Density Index were carried out. One case scenario relating to the face salvage was described and some initial analysis performed. The underground test sites were selected and methodology of support load and convergence measurements and rockmass geomechanical properties characterisation was developed. Convergence data from two German mines (20 roadways and drifts) were collected. Some initial work was performed in order to accomplish the rock bolts test and to develop the rock property database. The appropriate methodology for geotechnical modelling was selected and numerical models of gateroads and salvages were created.
