Unconformity-Related Uranium Deposits definition: Unconformity [ŭn′kən-fôr′mĭ-tē] A surface between successive strata representing a missing interval in the geologic record of time, produced either by an interruption in deposition or by the erosion of depositionally continuous strata followed by renewed deposition. An unconformity is a type of discontinuity.  or: An unconformity is time gap…

Sandstone uranium deposits are mineralizations hosted in medium- to coarse-grained sandstones that were deposited in continental fluvial or marginal marine environments. These deposits are typically associated with interbedded impermeable shale or mudstone units, which often lie immediately above and below the mineralized sandstone. Uranium is precipitated under reducing conditions, which can be…

Key Points Research suggests the optimum block size for a small open pit mine with a porphyry deposit is around 10m x 10m x 10m, balancing accuracy and computational efficiency. It seems likely that block dimensions are influenced by bench height (typically 10m), shovel width (around 3m), and deposit uniformity, but exact sizes vary by mine specifics. The evidence leans toward smaller blocks…

Key Points The optimal block size in open-pit mining varies based on mine-specific factors like geology and equipment, but research suggests typical sizes range from 10–20 meters in height and 20–50 meters in width and length. It seems likely that block height equals bench height, usually 12–15 meters for large mines, while width and length depend on shovel and truck operations. The evidence…

ExsolutionOrogenyAccretionOceanic-Continental Convergence: The Conditions for Plate Accretion Exsolution In mineralogy, exsolution is a process through which an initially homogeneous solid solution separates into at least two different crystalline minerals without the addition or removal of any materials. This phenomenon typically occurs when a mineral cools below the temperature at which its…

Key Points It seems likely that vocational training in mines is required to enhance the knowledge and skills of mining personnel for safe and efficient work, given the hazardous nature of the industry. Research suggests that trainers must have at least 5 years of mine experience, be safety-minded, skilled, and have an aptitude for training, with no prior rejection from production. The evidence…

Key Points It seems likely that safety officers in mines must have specific qualifications based on the mine type and size, as outlined in regulations under the Mines Act, 1952. Research suggests that for belowground mines with higher outputs, a First Class Manager’s Certificate (unrestricted) is required, while opencast mines may accept restricted certificates. The evidence leans toward…

Timber support in coal mine Side Support:  Wooden laggings are placed tight between vertical props and pillar where the sides are weak and need support. Sometimes the timber set of prop and bar has to resist pressure from sides which tend to crush into the roadways. Notching is useful in such cases. The props should be set at an angle of 14° to 20° off the vertical and the feet well sunk into…

Key Points Zero energy buildings produce as much energy as they consume using renewables. They use efficient designs and technologies like solar panels and heat pumps. They’re becoming more common to fight climate change and save energy costs. What Are Zero Energy Buildings? Zero energy buildings are structures designed to have no net energy consumption over a year. This means they generate…
