摘要:
锚喷支护技术是矿山工程控制围岩稳定的主要技术之一，而数值模拟技术的应用使得锚喷支护设计可以更客观地考虑巷道围岩与锚喷支护体之间的相互作用，在多支护方案比较时选出最优方案，具有较高的科学性和合理性。结合凌源?招丝笠倒旧畈-150 m开拓巷道工程实际，设计采用锚喷支护方式对局部破碎地段进行强化支护，并提出了3种支护参数优化方案，通过Flac3D软件对巷道开挖、支护过程进行模拟计算，获得了不同支护参数优化方案的巷道围岩应力、位移及支护体的力学特征，为巷道支护方案优化提供理论依据和技术指导。

Abstract:
Bolting and shotcreting support technology is one of the main means to control the stability of surrounding rocks in mining engineering,and the application of numerical simulation technology makes the design of bolting and shotcreting support more objective by considering the interaction between roadway surrounding rocks and the bolting and shotcreting supporting body.It is scientific and reasonable to select the optimal scheme by comparing multiple support schemes.Based on the engineering practice of deep -150 m development roadway in Lingyuan Rixing mining company,bolting and shotcreting support is designed to strengthen support in local broken area,and three optimization schemes of support parameters are put forward.Through the simulation calculation of roadway excavation and support process by Flac3D software,the surrounding rock stress,displacement and mechanical characteristics of the supporting bodies of different optimization schemes with support parameters are obtained.The purpose of this paper is to provide theoretical basis and technical guidance for the optimization of roadway support scheme.
