为了研究煤系地层岩石单轴抗压强度与弹性模量间的关系,以淮南矿区某矿378组岩石样本为研究对象,基于岩性不同,将这些岩石样本分成6类,以弹性模量为自变量,单轴抗压强度为因变量,分别采用线性函数、二次函数、幂函数3种回归模型对二者之间的关系进行拟合,获得若干回归拟合关系式。经过分析比较,构建了6个分别针对这6类岩性的岩石抗压强度与弹性模量关系式,并通过在顾北矿中的应用,对给出的回归拟合关系式的可靠度与适用性做出了说明。
In order to study the relationship between uniaxial compressive strength and elastic modulus of coal measure strata, 378 rock samples from a mine in Huainan mining area are taken as the research object. Based on the lithology, these rock samples are divided into six categories, and the elastic modulus is Independent variables and uniaxial compressive strength as dependent variables, the regression equations of three kinds of linear functions, quadratic functions and power functions were fitted respectively to get the regression fitting relations. After analyzing and comparing, the relationship between compressive strength and elastic modulus of six rocks respectively corresponding to the six types of lithology is constructed. Based on the application in GuBei mine, the reliability of regression regression equation and Applicability made a note.
