摘要
通过对煤矿井下巷道支护参数的确定,利用FLAC三维数组建模软件对井下巷道支护过程中的锚杆间距、应力分布区间等进行了仿真分析,并提出了支护优化方案。根据实际应用表明,该方案能够极大提升煤矿井下巷道的掘进速度和安全性,具有应用推广价值。
Through the determination of the supporting parameters of underground roadway in coal mine, the simulation analysis of bolt spacing and stress distribution interval in underground roadway support process is carried out by using the software FLAC three-dimensional number construction model, and the support optimization scheme is put forward. According to the practical application, this scheme can greatly improve the driving speed and safety of underground roadway in coal mine, and has the value of application and popularization.
