841103 Influence of engineering geological data on the design of underground structures and on the selection of construction methods

841100 Optimization method to calculate the stability of underground structures (In French) Minchev, I T "v.~ Proc International Symposium on Engineering Geology and Underground Construction, Lisbon, 1983 V1. P3.1-3.8. Publ Lisbon." SPG, 1983 The stability of underground constructions depends on the stress state of the rock mass. The stress state of the mass is expressed by the components of the stress tensor. A study of the extreme values of the contact stresses shows that such stresses appear with absolutely rigid constructions. The contact stresses represent the optimum value of the rock pressure. The elements of the underground construction are dimensioned on the basis of that pressure.

Proc International Symposium on Engineering Geology and Underground Construction, Lisbon, 1983 V1, P3.117-3.120. Publ Lisbon." SPG, 1983 Emphasizes the need for geotechnical studies in the design and execution stage of underground works to be complementary.
841102 Influence of engineering geological data on the design of underground structures and on the selection of construction methods: engineeringgeological activities during construction. Contractual documents. Liability M orfeldt, C O
Proc International Symposium on Engineering Geology and Underground Construction, Lisbon, 1983 V2, P3.5-3.24. Publ Lisbon: SPG, 1983 A brief summary of 18 papers presented at this symposium considering problems encountered during underground construction, particularly tunnelling through rock. A number of case studies are considered.
841103 Influence of engineering geological data on the design of underground structures and on the selection of construction methods Egger, P
Proc International Symposium on Engineering Geology and Underground Construction, Lisbon, 1983 V2, P3.27-3.39. Publ Lisbon." SPG, 1983 The combined effects of various engineering geological parameters of the rock mass on the most appropriate design and execution methods of underground openings are emphasized and their impact illustrated by examples.

841104 Rock mechanics in mining practice (South African Institute of Mining and Metallurgy Monograph Series No 5) Budavari, S (editor) Johannesburg." South African Institute of Mining and Metallurgy, 1983, 282P Includes chapters on: solid mechanics, rock and rock mass mechanical properties, response of the rock mass to excavation, design of mine tunnels and selection of support, design, support
and behaviour of mined tabular deposits, pillars and pillar extraction, use of fill for ground control, and rock burst phenomena.
841105 Stability of underground workings in the soft rocks of the Coal Measures Wilson, A H int J Min Engng V1, N2, July 1983, P91-187 The characteristics of soft rocks typical of the British Coal Measures are defined and a series of working hypotheses are developed to provide improved design methods for underground roadway and face supports and pillars in coal mines. Proposed design equations are tested against case history data. Auth. 59 refs.
841106 Effective stiffness and strength parameters for plane strain analysis of a dipping joint. Technical note Coulthard, M A; Crotty, J M Int J Rock Mech Min Sci V20, N5, Oct 1983, P243-246 The behaviour of a major fault which transects a substantial pillar in the 1100 orebody at Mount Isa Mine, Australia has been studied. To permit modelling of the system in 2-D, stiffness and strength parameters have been calculated for a model fault which dips normal to the plane of analysis and which is, within the plane strain approximation, equivalent to the real fault with arbitrary dip.
841107 Application of in-situ tests to dimensioning of room-pillar (In Turkish) Arioglu, E Kaya Mek Bal N1, Oct 1982, P35-40 Presents an analysis for dimensioning pillars which may be used to evaluate the limiting depth below which the room and pillar method is inapplicable due to mining parameters and pillar strength.
841108 Vertical shaft maintenance conditions assessed by the finite equilibrium method (In Russian) Fisenko, G L Shakhtnoe Stroit N2, Feb 1983, P7-11 The strengths and internal friction angles of mudstone and clay and their effects on elastic movement at the shaft contour are considered. The design of shaft support to accommodate stresses imposed by variations in the surrounding strata is examined and it is concluded that rigid and reinforced concrete are unacceptable in this application.

Proc International Symposium on Engineering Geology and Underground Construction, Lisbon, 1983 V I , P2.25-2.32. Publ Lisbon." SPG, 1983 Examines rock compaction caused by dewatering. Rock strength and deformation can be determined and used to estimate the stability and the support requirements of mines.
