摘要
总结了现今煤矿支护产品的应用现状;从理论上,论证并提出了提高预拉力措施,从巷道顶板的稳定性、工作的可行性考虑,提出了优化锚杆的参数和预应力的合理配置、加强锚杆检测技术及施加水平应力等相关建议。
Sums up application status of coal mine supporting products, theoretically, demonstrates and puts forward improving pretension foree measures. Considering stability of tunnel roof and working feasibility, it puts up with suggestion of optimizating parameters of bolt and proper configuration of pretension force, strengthening bolt detection technology and applying horizontal stress.
