• Mechanical properties of Michigan Basin's gypsum before

    Aug 01, 2019· 1. Introduction. Determining the mechanical properties of gypsum rock is important in many engineering projects including the stability of abandoned underground gypsum mines, especially for mines that become flooded after mining operations have been completed (Doulati Ardejani et al., 2013).Uniaxial compressive strength (UCS) is one of the most widely used rock parameters in design

    CharacteristicsProductionUsesGypsum is a mineral found in crystal as well as masses called gypsum rock. It is a very soft mineral and it can form very pretty, and sometimes extremely large colored crystals. Massive gypsum rock forms within layers of sedimentary rock, typically found in thick beds or layers. It forms in lagoons where ocean waters high in calcium and sulfate content can slowly evaporate and be regularly replenished with new sources of water. The result is the accumulation of large beds of sedimentary gypsum. Gypsum is commonly as
