#SIMULATION CHECKS HOW TO#

How to determine grade risk? Simulation is the answer Conditional SimulationĬonditional Simulation gives the user numerous equi probable results for any panel.

Low risk blocks would be in areas of consistent grade and the probability that the estimated grade of the block exceeding the economic cutoff grade would be high.The greater the grade variability present  The greater the risk that the estimated grade is not achieved.High risk blocks would have a high probability that the grade mined from that block would be less than the economic cutoff grade.Grade risk is a function of the grade variability present within the selected mining unit (panel) and the probability that the grade present within that panel exceeds the economic cutoff grade.What is grade risk? Grade Risk: The risk of not meeting estimated grade **Uncertainty associated with geological interpretation and grade estimation is usually the largest source of potential error in the resource and reserve estimate** The greater the uncertainty the greater the risk! RISK is commonly not quantified at any of the technical stages Resource and Reserve risk Resource and Reserve estimates Ore Geological Resource definition interpretation estimate Geological Uncertainty More difficult to quantify If you understand the risks present then you can mitigate the impact of these risks with good management and decisions.Įconomic Uncertainty Dynamic Constantly Changing Risk = Likelihood x Consequence What is the likelihood that you will be injured? How severe will be your injuries? Is the risk acceptable?

#SIMULATION CHECKS INSTALL#

Install Simulation PackageRisk assessment using Minesight software & Python scripting This Gazebo Simulation uses ROS Gazebo package, therefore, proper Gazebo version for ROS1 Melodic has to be installed before running this instruction.

#SIMULATION CHECKS PC#

Please follow the PC Setup instructions if you did not install required packages and dependent packages.

Without these prerequisite packages, the Simulation cannot be launched. The TurtleBot3 Simulation Package requires turtlebot3 and turtlebot3_msgs packages as prerequisite. This Gazebo Simulation uses ROS Gazebo package, therefore, proper Gazebo version for ROS1 Kinetic has to be installed before running this instruction. The contents in e-Manual can be updated without a prior notice and video contents could be outdated. In this instruction, Gazebo will be mainly introduced which is most widely used among ROS developers.

If you need to perform SLAM or Navigation, Gazebo would be a feasible solution as it supports sensors such as IMU, LDS, and camera.

The fake node is suitable for testing with the robot model and movement, but it does not support sensors.

There are two development environments to do this, one is using a fake node with 3D visualization tool RViz, and the other is using the 3D robot simulator Gazebo. TurtleBot3 supports simulation development environment that can be programmed and developed with a virtual robot in the simulation.

Launching the Simulation for the first time on the Remote PC may take a while to setup the environment.

Please run the Simulation on Remote PC.
