支护结构信息化监测在马头门处围岩的应用

Supporting Structure Information Monitoring of Surrounding Rock at Ingate Applications

张集煤矿东进风井马头门处围岩断面尺寸大、应力大,施工扰动产生的影响明显。为了实现信息化施工,能实时监测、评估支护结构的可靠性和围岩的稳定性,在马头门处施工过程中,进行了现场监测工作。监测内容主要包括收敛观测、锚杆及锚索受力、碹体受力及底臌观测。

East wind sheet sets coal mine shaft ingate section size big , stress of surrounding rock, the construction disturbance effect is obvious. Therefore, in order to realize the informationization construction,real - time monitoring,to assess the reliability of the supporting structure and the stability of surrounding rock, con-struction process, at ingate monitoring was carried out. Monitoring content mainly includes convergent observation, bolt and anchor cable force, floor drum up the self - closed stress and observa-tion.
