摘要
在复采区巷道掘进过程中,有时会出现穿过煤矿采空区的现象,这会在很大程度上增加掘进施工的挑战性,容易形成冒落区等问题,影响掘进作业的效率,同时也会带来更大的安全威胁。这使得复采区掘进巷道的支护显得尤为重要,需要做好过采空区围岩稳定性分析,并在此基础上合理应用支护技术,确保施工的安全性。基于此,本文分析了巷道掘进过采空区围岩的稳定性,并就相关支护技术的应用进行探究,仅供大家参考。
In the process of roadway tunneling in the secondary mining area,sometimes the phenomenon of passing through the goaf of the coal mine occurs,which will greatly increase the challenge of tunneling construction,easily form problems such as caving areas,affect the efficiency of tunneling operations,and also bring greater security threats.This makes the support of the roadways in the secondary mining area particularly important.It is necessary to do a good job in the stability analysis of the surrounding rocks in the goaf,and on this basis,reasonably apply the support technology to ensure the safety of construction.Based on this,this paper analyzes the stability of surrounding rock in the goaf through roadway excavation,and explores the application of related support technology,for your reference only.
