GB/T 23561.7-2009 Methods for determining the physical and mechanical properties of coal and rock—Part 7:Methods for determining the uniaxial compressive strength and counting softening coefficient
Abstract
This part of GB/T 23561 specifies the terms and definitions, instruments and equipment, specimens specifications, test procedures, and data calculation involved in the determination of uniaxial compressive strength and the calculation of softening coefficient for coal and rocks.
This part is applicable to the determination of uniaxial compressive strength and the calculation of softening coefficient for coal and rocks in coal seams that can be processed into standard specimens under laboratory conditions.
