摘要
为保证煤炭开采环境的安全性,通过对巷道锚杆支护进行数值模拟来对巷道锚杆支护性能进行研究。针对某矿工作面风巷掘进期间保证巷道支护强度,防止和杜绝顶板事故,采用FLAC3D软件进行数值模拟分析,构建巷道锚杆支护数值模拟模型。模拟结果表明,在采用相同间排距时,可通过改变锚杆规格的方式来提升支护的性能,实现巷道锚杆支护优化。
In order to ensure the safety of coal mining environment,through the numerical simulation of roadway bolt support,studied the performance of roadway bolt support.In view of a certain mine working face during the excavation of the air roadway to ensure the strength of roadway support,to prevent and eliminate roof accidents,the numerical simulation analysis were carried out by using FLAC3D software,and the numerical simulation model of roadway bolt support was constructed.The simulation results show that when the same row spacing is adopted,the support performance can be improved by changing the bolt specifications,and the roadway bolt support optimization can be realized.
