Abstract:
This paper presents a unique method of monitoring the
effectiveness of the planning process as well as the execution of
mine plans. The method primarily determines the degree of
deviation from the original mine plans by comparing actual mined
areas to initially planned mining areas. The performance of mining
operations is also measured by comparing actual and planned
tonnages for a particular period. Once the degree of deviation from
mine plans has been established the cause/s of the deviation can be
determined through a simple fault tree analysis. Accurate identification
of the reasons of deviation can aid the mine in selecting
possible methods to correct the deviation. It is, however, beyond the
scope of this paper to discuss the methods employed in correcting
such deviations, as each mining operation will have unique causes
of plan deviation and methods of remedying them. Deviations from
the plan greatly affect the yields obtainable, which in turn affects
the life of mine, thus having negative economic and financial
implications. Accordingly, this paper presents a project management
method which aims to reduce risk by improving planning systems to
ensure optimum overall extraction of coal reserves.
