摘要
应用红外探测技术,进行了不同锚杆参数的锚固体加载过程红外辐射实验研究,结果表明,锚固体红外辐射温度与轴向应变呈线性正相关,锚固体红外辐射温度上升速度和最大值高于非锚固体;不同锚杆参数的锚固体,锚杆越长、直径越大,其温度的升高越快且高。实验结果对于揭示锚杆支护作用机理、矿山煤岩灾害监测、预报等具有重要意义。
The infrared radiation experiments on the bolted rock of different parameters in the process of loading were carried out. It was found that the relationship between infrared radiation temperature of bolted rock and its strain was positive linearly related. The rising rate and maximum of infrared radiation temperature of bolted rock was higher than non-bolted rock. The more the length of bolt is and the larger the diameter is, the more rapid and higher the temperature of the bolt increases. It is of significance for disclosing the mechanism of bolt support, monitoring and predicting of mine rock disaster.
