Also, a constrained block model can be created from the original block model to increase performance.ДЇor a better user experience, displaying large block models can be performed after applying constraints or displaying block models as a point cloud. We can solve this challenge by applying partial percentage estimation as a volume adjustment when generating block model reports in Surpac. The accuracy of block model volume reports вЂ“ it can prove difficult to approximate the volumes of domain wireframes.

What are some common challenges in block modeling? Multi-threading in block models is now available in Surpac, which dramatically reduces estimation processing time from hours to seconds.

As computers become more powerful and better algorithms are developed, we can work with models containing millions of blocks. What are some common block modeling applications ?ДЄs the block model is a database, it can be used as input for strategic and tactical planning purposes as well as in the infrastructure design process. Several standard validation checks should be carried out at each step of the block modeling process, such as visual checks of local trends and statistical validation (Swath Plots). How are block models validated?ДЄt the end of the estimation, validation is necessary to ensure the estimate honors the original data or input information. Block models are also used with mine planning tools to maximize value through scheduling. It also helps in cutting costs by reducing further drilling or sampling costs, while producing optimal estimation parameters.

Mining software reduces the risks in resource estimation by providing the tools to visualize, analyze and validate a block model. During the investigation stage, technology is used for domaining, statistical analysis and geostatistical investigations. Technology spans all areas of the block modeling process, from data collection and investigation through to the creation of the block model and reporting.ДЄs an example, during the data collection stage, software is used to store and validate data to produce an accurate geological database. What role does technology play in the block modeling process? If you missed the Chat, you can read the summary below or the transcript. We also talked about how GEOVIA Surpac TM performs block modeling and provided tips on superblocking, validation, tagging and depletion. Throughout the chat, we discussed how block modeling helps mining companies cut costs and reduce risks in resource estimation. Hosted on Twitter at the interactive Q&A session addressed some of the issues when working with large datasets, the role of technology in the block modeling process, and block model applications.Д«lock models are, quite literally, the building blocks of any mining operation as it represents the entire deposit, and can determine the overall success of the mining activity.ДЄs a spatially-referenced database, a block model is an effective method of estimating volume, tonnage and the average grade of a 3D body from sparse drillhole data.

We held our second Twitter Chat, #AskGEOVIA, last week to explore block modeling concepts and some common challenges faced in this area. TodayвЂ™s post comes from Claver Gnamien, one of our Mining Knowledge Consultants.
