摘要
针对大断面穿层巷道围岩的特殊性和复杂性及巷道支护存在的问题,通过对山西吕梁地区某矿井大断面穿层回风大巷进行锚杆支护参数数值模拟研究,为类似条件下的穿层巷道支护设计提供了很好的依据和借鉴。
For the particularity and complexity of surrounding rocks in big section strata crossing road- ways and supporting problems, the parameters of anchor support by numerical simulation are studied in a mine in Lvliang area. The study offers a basis and a reference for the similar support design.
