The concept of longwall mining in the United States dates back to the late 19th century when wide faces were used for coal extraction in the Pittsburgh seam. But modern, fully mechanized longwall mining employing plows and frame supports was first introduced from West Germany in the early 1950s in southern West Virginia. It was used mainly for thin seam mining. During the 1950s and 1960s, the practice did not expand. In fact, due to its poor performance, only a few mines in southern West Virginia employed this technique.

Современное состояние подземной разработки кимберлитовых месторождений Якутии характеризуется сложностью горногеологических и горнотехнических условий, таких как: большая глубина работ, карьерное выработанное пространство, подземные высокоминерализованные водоносные комплексы и криолитозона, состоящая из многолетнемерзлых, мерзлых пород, имеющих существенное различие физико-механических свойств.

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. <...>

You can complete this training module in a self-paced environment or as a guided training course. You will use a variety of tools and functions within Deswik.Sched to complete the course.
This tutorial is a dual-purpose training module containing a mix of reading theory and practical exercis

Fast, efficient drill and blast designs for underground mining methods.
This tutorial includes instructions and information on the Deswik.UGDB module in Deswik.CAD. You can then design and plot rings for a typical underground stoping operation.
You can then apply these concepts to other underground drill and blast design projects.

Ore is an economic concept. It is defined as a concentration of minerals that can be exploited and turned into a saleable product to generate a financially acceptable profit under existing economic conditions. The definition of ore calls for afterthoughts. Ore does not properly exist until it has been labeled as such. To name a mineral prospect an ore body requires more information than needed to establish metal grades. Sufficient knowledge of the mineral deposit, mining technology, processing methods, and costs is needed for undertaking a feasibility study and proving the prospect worthy of being developed into a mine.

This tutorial provides an introduction to the common tools and functions contained within Deswik.CAD in an Underground Hard Rock operation, however as this tutorial is an introduction to Deswik.CAD functionality, the learning’s can be applied generally.
This tutorial is designed to be used in conjunction with the training data folder 4.01 Intro to CAD for  Underground Hard Rock containing all of the training data, software files and a completed set of CAD exercises.

Deswik.SO (Stope Optimizer) is a strategic mine planning tool that automates the design of stope shapes for a range of stoping methods for underground mines. The goal is to maximize the value of an orebody given the constraints using a certain mining method and design parameters. The outputs (stope wireframes, section strings and reports) are suitable for use in strategic and tactical planning <...>

Данный модуль можно изучить самостоятельно или в рамках учебного курса под руководством преподавателя. Для завершения этого курса вам понадобится использовать ряд инструментов и функций Deswik.CAD.

Настоящее руководство представляет собой комбинированный учебный модуль, содержащий теоретические сведения и практические задания. <...>

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:
