DESCRIPTION - summary of the module content
AIMS - intentions of the module
The module provides specialist design skills associated with quarry, civil, geotechnical, environmental and related industries. The module also provides an opportunity for students to gain an awareness of hazard appraisal and risk assessment applied to slope instability assessment.
INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)
SYLLABUS PLAN - summary of the structure and academic content of the module
The main subject areas are slope failure mechanisms, slope design, case histories, stabilisation, excavation methods and blast design. Stereographic interpretation is used to assess the kinematic potential for different types of slope failure (plane, wedge, topple). Deterministic and statistically based computer methods are introduced for analysis of slope failures and designs of new slopes. Design parameters are determined from laboratory and field-testing and back-analysis. Shear strength of discontinuities are evaluated. The effects of water pressure and stabilisation by dewatering, regrading and ground anchors are introduced. Case histories are introduced of slope failures and stabilisation measures taken from civil and mining engineering experience. Implications of tip and tailings dam design are reviewed, together with an appreciation of the geotechnical implications of the Quarries Regulations (1999). The composition and characteristics of commercial high explosives and blasting agents are studied including the use of electric and non-electric detonation systems, misfires, regulations and safety. Blast design includes the design path to an optimum blast, bench dimension specifications, blasting geometry, charge calculations, single and multi-row blasts.
