摘要
以煤试块流变试验及其显微煤岩组分与微观损伤的图象分析测试为例,介绍了煤岩作为一种复杂的特殊力学材料的流变特性;初步探讨了显微煤岩组分及其含量、煤岩内部微观损伤裂隙含量(裂面面积率)对煤岩强度的影响规律。煤的流变系数低于岩石材料,且煤的单轴抗压强度与煤的显微组分含量和微观损伤密切相关。
The rheology experiment, maceral and microfracture image analysis of coal blocks are made, and the reological property of coal rock is presented. The effect law of coal maceral, its quantity and ratio of fracture area on coal block′s strength are explored.
