Azimuth and gradient search parameters allow the user to define the search direction of the spatial link. Azimuth search parameters can be used to link from undercut rings to first task in drawpoint drive using defined azimuth search direction, this will drive the direction of the SLC front. Gradient search parameters are similar, an example being stope linking in narrow vein steeply dipping stopes. <...>

Анмизируются и классифицируются современные методы установления ироизводительиостл карьеров. Привддятся наиболее совершенные аналитические, графические и графо-аналитические методы установления развития возможной производительности карьера по горно-техническим факторам, но транспортным условиям; методы установления производительности по экономическим факторам.

Развитие открытого способа угледобычи в период 1990-1998 гг. характеризовалось двумя тенденциями: систематическим снижением объемов добываемого разрезами угля и ростом его удельного веса в годовых объемах добычи (за счет более быстрого снижения объемов подземной добычи). Только за последние два года объемы открытой угледобычи увеличились: до 153,4 млн т в 1999 г. и до 165,1 млн т в 2000 г.

Deswik.IS (interactive scheduler) bridges the gap between designing and scheduling.

Deswik.IS produces a Gantt chart schedule that you can change and update via Deswik.CAD.

The planning engineer can make changes to the graphics, and the results update in the schedule. This facilitates rapid schedule development, with time to analyze scenarios, rather than manipulate data. The main features of Deswik.IS include:

This tutorial provides an introduction to the common tools and functions contained within Deswik.Scheduler in an Underground Hard Rock Operation, however as this tutorial is an introduction to Deswik.Scheduler functionality, the learning’s can be applied generally.

Carrapateena is an underground sublevel cave operation. To maximise future value from the Carrapateena copper–gold resource, an expansion study has been completed to feasibility study level to assess a larger block cave expansion below the current sublevel cave. This paper will summarise Carrapateena block cave mine design and planning from pre-feasibility to feasibility study.

Conventional mine planning processes result in the selection of pushback widths that maximize equipment productivity. This paper challenges the current notion that pushback width should be set at the distance that assures maximum equipment productivity. A hypothetical case study is presented, which shows that the value of a project may increase beyond that determined by traditional planning practices. It was found that it may be better to deploy more aggressive mining strategies, which are likely to result in greater operational complexity and thus reduced equipment productivity. A higher equipment productivity, which often corresponds to wider (and therefore a lower number of) pushbacks, will also often result in later ore extraction and require higher capital costs. 

It is a privilege to introduce “Advances in Applied Strategic Mine Planning”, a collection of technical papers addressing core aspects of the sustainable, responsible and optimal development and utilization of Earth’s mineral resources. In a world of uncertain markets, mismatches between demand and reserve base growth (supply), emerging technologies, and new technical challenges and solutions, this book aims to support knowledge dissemination and mobilization of new concerns, concepts, methods and technologies.

The Global Optimiser used by Whittle Consulting has gone through three major versions to date. The first was based on the Milawa optimisation algorithm; it worked, but had many shortcomings. The second, known internally as ProberA, had a different approach to optimisation in that it used a series of random starting points and found the nearest local NPV maximum to each.
