Most Common Types of Mining Equipment in Use in 2023
Miners can unearth surface material through strip mining, quarrying, and open-pit mining. In addition, those different mining methods bring various mining equipment into the enclosed environment of underground work, such as massive earth-moving trucks and rotary drill rigs. Surface and blast mining often go hand-in-hand since …

Long-Term Stability and Deformation Behaviour of Anhydrite
The anhydrite rock in this mining area is dense and has low porosity, high strength and stiffness, with an average density of 2.94 g/cm 3. To test the creep properties of anhydrite rock, this work developed the uniaxial compressive creep test (Fig. 3). The used rock samples are two cylindrical samples in the natural state, with diameter 50 mm ...

Gypsum Mineral | Uses and Properties
Gypsum is an evaporite mineral most commonly found in layered sedimentary deposits in association with halite, anhydrite, sulfur, calcite, and dolomite. Gypsum (CaSO 4. 2H 2 O) is very similar to Anhydrite (CaSO 4). The chemical difference is that gypsum contains two waters and anhydrite is without water. Gypsum is the most common sulfate mineral.
