Experimental Research on the Influence of Temperature on the Static Properties of Skarn

Studying the high-temperature mechanical properties of rocks is great significance to engineering disasters caused by deep rock mining and underground protection projects. In view insufficient research on in southwestern China, we used heating devices statics equipment conduct static tests Skarn. XW7L-12 box-type resistance furnace was adopted heat Skarn (25°C, 200°C, 400°C, 600°C, 800°C), temperature effect its basic physical parameters (density wave velocity) measured analyzed. Uniaxial compression experiments were performed two cooling methods (natural water cooling) a constant stress pressure testing machine obtain stress-strain curve analyze index (peak strength, tensile elastic modulus, peak strain) change rule failure mode with rise different methods. With increasing, various indexes will be greatly affected. Meanwhile, are not related trend under high temperature.
