JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives

To give details of slope design principles for opencost mines including

basic mechanism of slopes failure, monitoring and instrumentation and remedial measures for slope stabilisation.

Course Outcomes

At present open cost mining methods are being practical for extraction of

mineral deposits at comparatively deeper horizans and experiencing slope stability problems as a challenge t mining engineers. Students can get a better knowledge on various slope failures, design of slopes and monitoring of stability of slopes and its stabilization measures.

UNIT - I

Introduction: economic implications, geological investigation, data interpretation for slope stability analysis.

UNIT - II

Basic Mechanism of Slope Failure: Planer, wedge, rotational shear, toppling, buckling and rock fall. Mechanism of failure of jointed rock mass. Determination of shear strength of discontinuities.

UNIT - III

Influence of ground water on slopes and techniques of depressurization, remedial and corrective measures. Remedial measures for slope stabilization.

UNIT - IV

Monitoring and instrumentation techniques of rock slopes. Investigations of failed slopes.

UNIT - V

Numerical analysis of slopes. Use of continuum & discontinues models and softwares.
