Study on mechanical properties of coal measures rocks with triaxial compression in Panji deep exploration
Taking the deep exploration area in Panji of Huainan as an example, the distribution characteristics of deep geological storage conditions for the coal measures rocks were comprehensively determined.In the variation range of measured in-situ stress condition, the strengthcharacteristics and deformation properties of coal measures rocks were studied by rock triaxial compression test system indoor.The coal measures rocks include 6 kinds of lithology: gritstone, medium sandstone, fine sandstone, siltstone, mudstone and limestone.The results showed that the high lateral pressure plays a important role in the mechanical properties of coal measures rocks.According to the analysis of the similarities and differences of each lithology rocks, the strength and deformation of coal measures rocks under the high stress field are controlled by the lateral pressure control greater than the influence of lithology.Results canbe applied to the deep engineering disaster prevention and stability evaluation of surrounding rocks.
