| 摘 要： | 应用X-衍射、荧光光谱分析和力学试验研究方法，研究了淮南新集井田煤系泥岩的矿物组成和化学成分特征；建立了泥岩的力学性质与其化学成分之间的定性定量关系，其表现为：随着SiO2含量的增大，泥岩的单轴抗压强度和弹性模量总体呈增大趋势；而随着烧失量的增大，泥岩的单轴抗压强度和弹性模量总体呈减小趋势。

| Abstract: | Based on the advanced methods of roentgen diffraction,fluorescence spectrum and mechanical experiment,this paper analyzes the mineral and chemical composition and its mechanical properties of mudstone of coal measures in Xinji coal mine,Huainan.The qualitative and quantitative relationship between the chemical composition of the roof & floor mudstone and the mechanical properties is established.It is shown that the uniaxial compressive strength and the elastic modulus of mudstone rise with increasing of the content of SiO 2,and reduce with increasing of the content of ignition loss. |
