锚杆支护巷道安全监测技术

Monitoring Technology Using Rock Bolting Engineering

锚杆支护巷道顶板冒落具有突发性和冒落面积大的特点 ,安全监测非常必要。笔者介绍了国内近年来最新研制的CM— 2 0 0型测力锚杆、GYS— 30 0型锚杆 (索 )测力计、LBY— 3型顶板离层指示仪、ZW— 4型遥测多点位移计等监测仪器 ;提出锚杆支护巷道动态信息施工方法 :监测施工、监测信息反馈、检验和修正设计 ,循环往复 ,以达到最佳施工效果。

Roof falling of rock bolting supported tunnel is usually paroxysmal in a big area, so safety monitoring is of great importance. Some new monitoring instruments are introduced such as CM—200 bolt monitor, GYS—300 cable measurer, LBY—3 roof movement measurer, and ZW—4 multiple points displacement extensometer. Dynamic informational construction method is put forward, which should be used to monitor the coal mine tunnel support, information feedback and design revising and applied reciprocally till the optimum construction is resulted.
