Time to production line is very important for ore production in major facilities of block caving mining such as Draw Point, Grizzly and Chute in extraction level to ensure the ore production flows as planned so the comprehensive project planning and scheduling, “real-time project monitoring, measuring and controlling are key to achieving the project completion target.

Underground construction projects that support the operation absolutely need accurate and real-time project monitoring, measurement, control and reporting to allow the project manager to manage the project and to respond to any problems that will affect the project completion promptly.

This paper is developed to introduce how the earned value management (EVM) method can be successfully used as a tool to generate real project monitoring, measuring and control in an underground mining project.

In this paper, the author demonstrates the use of Earned Value Management in underground mining operations using the block caving method and concludes that EVM could be applied effectively in the operation’s activity.

Keywords: block caving, draw point, real-time monitoring, Earned Value Analysis, SPI, operational applications of earned value management


Underground Mining with block caving (figure 3) method is a concatenated process of several activities that have dependency among others such as Mine Planning and Engineering, Mine Development, Underground Construction, Production and Ore Flow. It is “the lowest production cost” (Butcher, Steffen, Robertson, & Kirsten, 1999) and has been applied to large scale extraction of various metals and minerals, sometimes in thick beds of ore but usually in steep to vertical masses.

As shown in (figure 1), underground construction is one of the activities in the mining operation process cycle that has special challenge because it not only deals with its own project risks and constraints but also has to deal with operational requirements.

This paper is developed to introduce how earned value management (EVM) method can be successfully used as a tool to generate real project monitoring, measuring and control in underground mining project.
