摘要:
巨厚砾岩层下的采场围岩极易形成应力集中而引发巷道失稳,其倾向支承压力分布规律是该问题的核心。文中通过建立采场倾向支承压力理论模型,对巨厚砾岩层下采场倾向支承压力进行了理论计算。随后搭建了巨厚砾岩层下采场三维物理相似模型,将分布式光纤技术用于模型试验采场支承压力测试,并对比研究了模型开挖过程中支承压力与光纤测试Brillouin频移之间的关系。结果表明,巨厚砾岩下倾向采动支承压力分布具有峰值大和影响范围大的特点,理论计算支承压力峰值为35 MPa,影响范围约200 m; 模型试验光纤测试曲线表明支承压力分布规律为从不变→增大→峰值→减小→不变的变化趋势,光纤测试结果与理论计算一致,通过光纤频移变化可以反映倾向支承压力的变化规律,为采场倾向支承压力监测提供了新的研究手段。
Abstract:
The stress concentration of the surrounding rock is very easy to cause the roadway instability under the supper thick conglomerate layer,which inclined abutment pressure distribution is the core of the problem.In this paper,a theoretical model of inclination abutment pressure is established,and the theoretical calculation of the inclined abutment pressure under the thick conglomerate is made.Then,a three-dimensional physical model of the underground mining under thick conglomerate is built.Distributed optical fiber technology is used to test the inclined abutment pressure in the model test.The relationship between the support pressure and the Brillouin frequency shift is studied.The results show that the distribution of the inclined abutment pressure under supper thick conglomerate layer has the characteristics of large peak value and large influential range.The peak value of the supporting pressure is 35 MPa,and the influential range is about 200 m.The optical fiber test curve of the model test shows that the distribution of inclined abutment pressure is from invariable→increase→peak→decrease→invariable.The results of optical fiber test are in accordance with the theoretical calculation,and the variation of the bearing pressure can be reflected by the frequency shift of the fiber,which provides a new research method for the bearing pressure test.
