RockMaster SWD (Seismic While Drilling)
While MWD data is useful, it alone it does not provide all the critical geoscience parameters required to optimize differential blasting. DataCloud has developed a proprietary IoT and cloud technology solution to augment MWD data by directly measuring blast critical mechanical parameters using Seismic While Drilling (SWD) technology at centimeter scale resolution. In SWD, the acoustic signals created by the interactions of the drill bit with the rock are detected using an array of geophones. These acoustic signals are directly related to mechanical properties of the rock such as Young’s modulus, shear modulus, bulk modulus and density. In some cases it’s possible to directly measure ore grade and identify specific geological features such as fracture zones. Whereas MWD provides measurements of rock properties in each blast hole, DataCloud’s RockMaster SWD technology augments this MWD data by measuring additional, very critical rock properties, between the blast holes.
RockMaster SWI (Surface Wave Imaging)
To optimize blast-hole configuration, DataCloud offers its Surface Wave Imaging (SWI) solution. SWI seismic techniques can quickly and efficiently provide a shear velocity image of the bench prior to drilling. Shear wave velocity can be used to directly calculate optimum blast hole spacing to help ensure a desired fragmentation profile is delivered. Passive seismic sensors used for SWI can also be used for blast vibration monitoring to develop better peak particle velocity (PPV) calculations for future blast design. This technology is also well suited to imaging subsurface voids such as karsts and old workings, thereby eliminating the need for expensive proof drilling operations.
RockMaster BHI (Blast Hole Imaging)
Another DataCloud proprietary technology solution involves the digital imaging of blast holes during the traditional “dipping” process. Without adding additional tasks, our Blast Hole Imaging (BHI) solution captures high resolution, oriented 360° blast hole images, and analyzes the images to identify joint (fracture) density, block size, orientation and dip, which are used as direct inputs to “blastability” indexes. These measurements take advantage of the dramatic improvements in the size, cost and reliability of today’s wireless sensors. Sensors are deployed autonomously and are enabled by the latest IoT protocols. Compared to what has previously existed in the industry, these new imaging sensors can be equated to upgrading a 1990’s cell phone to the latest smartphone technology.
RockMaster MWD (Measurement While Drilling)
The DataCloud solution starts by making maximum use of drill-generated Measurement While Drilling (MWD) data. This data is uploaded to the cloud and integrated in real-time with the starting geological/mechanical model developed from core and exploration data, and legacy MWD data set. The mechanical specific energy exerted while drilling blast holes is mapped in 3D and rock property distributions are subsequently calculated with advanced geostatistical techniques developed by DataCloud. Drill bit and drill performance variations are automatically calibrated and normalized. The dataset can be viewed and put to use immediately by the drill and blast team. This dataset can immediately identify hard rock requiring additional explosive energy, and weak zones that may require less energy.
MinePortal (“Earth Model” Geoscience Data Platform)
The MinePortal is a real-time “Earth Model” platform for real-time management and analyzing of the geosciences data generated by DataCloud’s sensor, measurement and seismic technologies. This cloud-based platform allows for integration of the exploration drill data, block models, and latest grade control measures into a single seamless cloud based platform with an intuitive user interface. It can be accessed from a browser or mobile devices. By analyzing all of this critical data in real-time, the mine operator can make better, faster drilling and blasting decisions that materially improve productivity.
MineMigrator (“Lift and Shift” Service)
MineMigrator is a DataCloud service that enables operators to seamlessly migrate legacy mine site data to the cloud. MineMigrator is not required to deploy other DataCloud product and service offerings. However, it allows operators to derive even more value from their DataCloud solutions (and from those of other client contractors as well). Key benefits of DataCloud’s MineMigrator service include simplicity, fast implementation, increased data security, and lower overall costs. In addition, this new service makes the mine’s data more accessible for essential analytics.
Grade Engineering Simulator (Currently Under Development)
DataCloud’s measurement solutions and geological models are driving significant improvements to the economic, environmental, and safety profiles of mining company operations. Now, DataCloud is partnering with Microsoft and Orica, the world’s leading supplier of blasting technology to the mining industry, to bring unrivaled expertise to the blasting domain. We are currently developing an industry-leading Grade Engineering Simulator that will provide our clients with a high resolution, real-time differential blasting plan. The plan will be produced via artificial intelligence, based on data derived from DataCloud’s MWD, SWD, SWI and BHI solutions, as well as from core and legacy blast performance data. Stay tuned to learn more about this exciting new solution from DataCloud.
