JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives

To introduce and differentiate the classical statistics and geostatistics for

precise resource evaluation, reserve calculations and ore body modelling as important components of mining operations.

Course Outcomes

Students understand the procedures for sampling, estimation reserves of

mineral resources and ore body modelling using geostatistics as outcome of this course, which is highly beneficial for the mining engineers for mine planning and development of mine.
