摘要(Abstract)：

利用SD-I型声波检测仪对山西寿阳15号煤层进行超声波速度测定;利用MTS815岩石伺服试验机进行强度实验,在此基础上讨论了纵波波速与煤岩强度的关系以及动静态弹性参数间的关系。结果表明:煤岩单轴抗压强度与纵波速度呈较好的指数关系,单轴抗压强度随纵波速度增大而增大;煤岩的动静态弹性模量之间存在较好的线性关系,且煤岩的动态弹性模量大于静态弹性模量;煤岩的动静态泊松比基本上呈正相关性。给出的煤岩动静态参数间的拟合关系式有助于今后做进一步研究。
Using SD-I acoustic detector,we examine the No.15 coal seam in Shouyang block of Shanxi Province.The uniaxial compressive strength test is carried out on the MTS815 Servo-controlled Rock Mechanical Test Sys-tem.We discuss the relationship between the velocity of P-wave and the coal intensity,and that between the dy-namic and static elastic parameters.Test results indicate that: uniaxial compressive strength of coal and the P-wave velocity show a good exponential relationship,uniaxial compressive strength increase with the P-wave velocity;the dynamic and static elastic modulus show a good linear relationship,and the dynamic elastic modulus is usually greater than the static elastic modulus;the static and dynamic Poisson’s ratio is positively correlated.
