摘    要:煤矿井下巷道被开掘后,生产应力会重新分布,若未能及时地对顶板采取妥善的支护措施,则井下的巷道围岩极易发生位移、变形。为了更好地推进煤矿企业的井下巷道作业工程,需在掘进过程中强化顶板的支护控制与管理。阐述巷道支护的材料及主要类型后,分析了常见的地质构造类型,结合实际案例探讨了井下地质构造对巷道支护的影响及注意事项。相关施工人员必须要充分地认识到矿区掘进技术及其地质构造对巷道支护产生的影响,在遇到褶皱、断层、复合顶板的状况时,进行科学合理的设计。

关 键 词:煤矿企业  井下作业  地质结构  巷道支护

Abstract:After the underground tunnel is excavated,the strata stress will be redistributed.If proper support measures are not taken for the roof in time,the surrounding rock of the underground roadway is prone to displacement and deformation.In order to better promote the underground tunnel work of coal mine enterprises,it is necessary to strengthen the support control and management of the roadway during the driving process.Based on the analysis of common types of mine geological structure,combined with practical cases,the influence of underground geological structure on roadway support and precautions was discussed.Technicians must understand the influence of driving technology and geological structure on roadway support,and carry out scientific and reasonable design when encountering the situation of fold,fault and composite roof.
Keywords:coal mine enterprise  underground operation  geological structure  roadway support
