In open-pit mines located in regions with high rainfall, the drainage system is crucial to the efficiency of mining operations. Driving effluents out of the pit requires tilting the mining benches in order to direct the water to previously studied collection points. This article explores how mining bank inclination and appropriate methodology can facilitate mining planning and sequencing in open pit mines. Importance of Drainage System in Open Cast Mines In areas with high rainfall, efficient drainage is vital. Accumulated water can compromise the safety and efficiency of mining operations. Therefore, tilting the mining benches to guide water to specific collection points is essential. However, designing inclined mining plans for extensive mines…

Field samples are, without a doubt, the most important part of evaluating and planning a mine. Incorrect information will result in failed resources and mining plans. The reliability of your data is fundamental. MinePlan Torque will offer the QA/QC module, a built-in, flexible and easy-to-use quality assurance and control tool designed to validate and determine the precision and accuracy of laboratory samples. To do this, it provides graphical and analysis functionalities for analytical samples, standards, blanks and duplicates. Project Setup and Data Management The QA/QC backstage allows you to create, edit, import attributes, laboratories, analytical methods, measurement methods, blank samples and standards, as shown in Figure 1. Once the project setup is complete , the user can manage all data with guarantee and control…
Geostatistics based on variogram allows to generate two types of block model: Estimated and simulated. Estimated models depend on the implementation of kriging methods to calculate the mean and variance of each attribute of interest in each block. A wide range of kriging methods can be implemented, including universal kriging, ordinary kriging, and simple kriging. Each of these methods is designed for a specific purpose. Simulated models rely on implementing Gaussian-based simulation methods, including sequential Gaussian simulation (SGS), LU simulation, and tuning band simulation, to generate equally likely deposit scenarios that honor the drillhole data. Any of these Gaussian-based simulation methods are expected to generate the same type of realizations for a given variographic model. These methods are different in the way they handle resources…
The design and scheduling of operations tasks are some of the most complex steps in sequencing and validating mining activities. In MineSight Atlas you can view and change your sequencing in real time, directly on the screen or through pre-defined restrictions, allowing the user to make his plan quickly and consequently have more time for analysis and improvement of his projects. In this Tips & Tricks we will highlight some types of restrictions that will help users to have better control and optimization of planned activities, imposing start and end methods for each activity. Finish By: This option allows you to define a date when the activity must be finished by allocating resources in order to meet a deadline. The resource allocation option for setting a date can be programmed in two…
When creating a geological model, interpolating or using it in mine planning, you will certainly need some kind of extra calculation for coding the block model, which is an essential part of the process, such as density coding, value economics, equivalent grades, classification codes, among others. For this purpose we have Model Calculation, which is a robust MineSight tool. With this it is possible to create several formulas to code in the block model in a timely manner, several limit options and possibilities of block-by-block tests before executing the formula in the entire block model, saving you time. The novelty now is that MineSight will release a revamped version of this tool, with a range of new features and a dynamic interface, in addition to transforming it into a plug-in, optimizing procedures. You…
Pit optimization is essential in mining, ensuring efficiency and maximizing profits. In this article, we will explore how to balance time, quality and cost when operationalizing pits and phases, highlighting practical strategies to achieve the best results. You've probably heard the saying “it's expensive to get cheap”, right? This usually happens when you chose the cheapest option and the end result does not meet your expectations. To obtain the desired quality, it is not always necessary to invest more resources but rather to optimize and/or adapt your demand, as “time is money”. The main strategy of a project is to balance the relationship between time x quality x cost. When we talk about quality, it is important to have a very clear concept that quality is suitability for use and also compliance with requirements, that is, defining what is important in demand. A…
Hexagon Mining | MineSight is bringing greater precision, reliability and flexibility into one of the most difficult stages of mining, through a new tool that is revolutionizing the design and execution of drilling and blast plans in mining. HxM Blast allows to improve fragmentation results, excavator loading rate, reduce secondary blasts, improve operational floor condition, slope stability and mainly increase productivity and reduce costs. In a single interface, the user can design drilling meshes, apply blast parameters to the holes, perform validations, interact with other MineSight tools, among other resources. HxM Blast will provide more control over drill mesh design, management and reporting and its modern interface reflects the look and feel of current MineSight products. One of the features…
Hexagon Mining has just released MineSight QAQC, a flexible and easy-to-use product for validation and determination of precision and accuracy in field samples. These field samples are arguably the most important parts of a mine assessment and design process. Incorrect assay information means failure of mine plans and potentially large financial losses. MineSight is a comprehensive mine planning platform that is used for mine modelling, design and sequencing. MineSight QAQC provides critical graphing and analysis functionality for analytical samples, standards, blanks and duplicates returning from the chemical analysis lab. The tool has full integration with MineSight Torque, which is Hexagon Mining's hole/sample manager. In the QAQC, there are components for statistical analysis of grade data from the laboratory, control…
MineSight Schedule Optimizer (MSSO) is consolidated in the market as the best and most complete tool for the short, medium and long term sequencing of open pit and underground mines. However, once again the MSSO stands out as an avant-garde tool, not only for its ease and excellent results in conventional sequencing, but also for opening up a horizon of new possibilities. In view of its great potential and the great results demonstrated, we would like to present the programming with MultiPeriod, which allows the grouping of periods so that the calculations are made in global periods, and not unitary ones as traditionally performed, thus resulting in an optimal global solution. with the best result for the proposed objective. With the use of the MultiPeriod option, we can mention two great advantages: First, this type of programming allows a global view and not just a specific one…
