摘要
近年来,随着我国铁矿资源的大力开采,矿产资源深度不断增加,矿产浅部资源逐渐枯竭,故而地下硐室开采建设施工也日益增多。然而,由于地下硐室围岩地质条件过于复杂、构造应力相对较大等不确定因素增加,矿产资源地下硐室稳定受到严重影响。大型硐室群的稳定性受损,则会造成一定灾难,影响矿建工程施工作业。本文以A矿区为研究背景,通过现场勘测结合理论性知识,对矿建工程中破碎围岩硐室围岩的稳定性进行系统研究,分析了矿区地质结构、构造应力和硐室稳定性。
In recent years,with the vigorous exploitation of China's iron ore resources,the depth of mineral resources continues to increase,and the shallow resources of mineral resources are gradually depleted,so the construction of underground chamber mining is also increasing.However,due to the increased complexity of the surrounding rock geological conditions of the underground chamber and the relatively large structural stress,the stability of the underground chamber of mineral resources has been seriously affected.Damage to the stability of the large group of chambers will cause a certain disaster and affect the construction operations of mine construction projects.Taking mine A as the research background,this paper systematically studied the stability of the surrounding rock in the broken wall rock chamber in the mine construction project through field survey and theoretical knowledge,and analyzed the geological structure,tectonic stress and chamber stability of the mine area.
