玻璃钢锚杆支护失效形式及相应对策

Support Failure Modes of Glass Fiber Reinfored Plastic Bolt and Corresponding Countermeasures

为推动玻璃钢锚杆在段王矿中的应用,采用现场实测、理论力学分析150405工作面玻璃钢锚杆失效总比例及失效形式。结果表明:玻璃钢锚杆在段王矿的支护可行,锚杆失效形式主要是配件失效和锚空失效,并针对这2种失效形式分别给出支护对策。

To promote the application of glass fiber reinfored plastic bolt in Duanwang Mine,We use field measurement and theoretical mechanics to analyze the total failure proportion and failure modes of glass fiber reinforced plastic bolt at 150405 working face.The results show that glass fiber reinfored plastic bolt support in Duanwang Mine is feasible; the main failure forms are fitting failure and anchor support failure; we give support countermeasures against these two failure modes.
