Decision support system for underground construction — a mining case study
189A the first time, allowing the machine to work continuously at optimum efficiency and without overloading the electric motors.
903468 Computer based decision support systems for underground construction Einstein, H H; Salazar, G F; Kim, Y W; Ioannou, P G Proe 1987 Rapid Excavation and Tunnelling Conference, New Orleans, 14-17 June 1987 V2, P1287-1308. Publ Littleton: Society of Mining Engineers, 1987 The system developed by the tunnelling group at MIT is described. The major modules are: geology module for estimating tunnel geology; geology updating module for incorporating information obtained during construction; exploration module for optimising exploration; construction simulation module for estimating production time and cost and for resource allocation: and decision support module for optimising construction procedures and for estimating time and cost. The system can be used in exploration, design, and construction stages of a project. 903469 Decision Support System for underground construction - a mining case study Miller, R M; Milligan, J Proc 1987 Rapid Excavation and Tunnelling Conference, New Orleans, 14-17 June 1987 V2, P1329-1341. Publ Littleton: Socieo' of Mining Engineers, 1987 Large quantities of oil were discovered in sands below the permafrost and above the producing reservoir of an arctic field. Recovery by construction of an 'underground platform' incorporating shafts, tunnels and wells was proposed. A DSS was required to handle the complex calculations involved for excavations through permafrost into soft ground,and to coordinate planning, operation, control and risk evaluation. The Project/2 software developed by MIT was selected. 903470 Rock movement monitoring of Rihand tunnels Prabhakar, B; Dube, A K; Saini, G S Proc International Symposium Tuanelling for Water Resources and Power Projects, New Delhi, 19-23 January 1988 VI, P349-354. Publ New Delhi: Oxford and IBH Publishing Co, 1988 Three parallel tunnels were driven through granite gneiss bedrock with 3 major joint sets. Strength and engineering properties of the rock mass are presented. Rock movement was monitored using tape and borehole extensometers, and rock load with load cells. A numerical method was employed to predict radial and tangential stresses and displacements. This predicted low stress and a similar displacement trend to that observed. 903471 Plasto-elastic model of lateral isotropic body on tunnelling Li Zonghua Proc International Symposium Tunnelling for Water Resources and Power Projects, New Delhi, 19-23 January 1988 V1, P359-364. Publ New Delhi." Oxford and IBH Publishing Co, 1988 An elastoplastic model of a laterally isotropic rock mass around a tunnel is proposed, and applied to tunnelling at Bi Kou HEP plant. The example shows that stability of the rock
mass around a tunnel is controlled largely by mechanically weak planes. Considering the case for strike of weak planes parallel to tunnel axis, equations for boundary of shear failure zone. shear stress, and strength along the closely spaced weak planes are developed. Calculated deformation and failure agree well with observed movements. 903472 Tunnel No.6 of Yongping mine, China Xu Qingda Proc International Symposium Tunnelling for Water Resources and Power Projects, New Delhi, 19-23 January 1988 VI, P365-367. Publ New DelhP Oxford and 1BH Publishing Co, 1988 A tunnel through poor karstic strata collapsed leaving a large surface depression. Because of natural arch formation and remedial measures, driving of the tunnel could continue. Soil and rock were allowed to collapse and pile up. After compaction and cementation, the soil column unloaded into an arch formation. 903473 Commentary of Li-tunnel for diverting water from Luan-River to Tianjin municipality Chao Kwang-Teh; Su Sheng-Kui; Wang Xue-Song Proc International Symposium Tuanelling for Water Resources and Power Projects, New Delhi, 19-23 January 1988 VI, P369-373. Publ New Delhi: Oxford and IBH Publishing Co, 1988 Construction of the Li tunnel is described. The geology and hydraulic and tunnel structure parameters used in design are outlined. 15 inclined drifts were driven to the tunnel aligment and smooth blasting from multiple faces was used for excavation. Support was dependent on rock condition, but was a combination of shotcrete, steel bars and concrete lining. 903474 Svartisen hydro power development scheme Johansen, E D; Dyrkorn, K Proc International Symposium Tunnelling for Water Resources and Power Projects, New Delhi, 19-23 January 1988 VI, P385-389. Publ New Delhi: Oxford and IBH Publishing Co, 1988 Construction of tunnels for the project, through mica schist, limestone and granite, began in 1987. The tunnels are being part blasted, part machine excavated, to gain advantages of both methods. Machine performance, planning and costs are outlined. 903475 Submerged tunnels for a fixed link across the Strait of Messina, Italy Pigorini, B Proc International Congress on Tunnels and Water, Mmtrid, 15-18 June 1988 VI, P!3-31. Publ Rotterdam: A A Balkema, 1988 Three tunnels, two road and one railway, will form the permanent link between the Italian mainland and Sicily. Submerged floating tunnels, anchored to the seabed, will be used for the straits section, and hydroshield driven tunnels onshore, through loose cohesionless soils and friable sandstones beneath the water table. Because of the history of seismic events in the region, seismic response of both offshore and onshore sections was evaluated during design.
