全螺纹玻璃钢锚杆在回采巷道支护中的应用

Application of Thread FRP Anchor in Extraction Roadway Support

全螺纹玻璃钢锚杆具有抗拉强度高、可切割、不产生火花等优点,在回采巷道支护中具有广泛的应用前景。王庄煤矿在综放工作面试验使用了新型全螺纹玻璃钢锚杆支护材料,经现场使用和矿压观测,能够满足工作面支护要求,有利于综放工作面安全高效生产。

The thread FRP anchor has advantages of tensile strength, can cut, do not produce sparks etc, and in return roadway in sup- porting has a broad prospect of application. Wangzhuang Coal Mine used new thread FRP bolt supporting materials in fully - mecha- nized caving face. Through using and observation, it can satisfied the mining face support requests, and useful to fully - mechanized sublevel caving production safety and efficiency.
