Experimental study on progressive failure characteristics of strip coal pillar models under different roof and floor conditions
To study mechanical properties and progressive failure characteristics of strip coal pillar, a progressive failure monitoring device was developed. The uniaxial compression test of “roof-strip coal pillar-floor” structure specimens were conducted. As the strength of the roof and floor increases, the...
