摘要
结合刘庄煤矿首采(E2-1305)工作面,通过数值模拟与工程实践结合的研究方法,比较不同断面形状对煤巷锚杆支护效果的影响,通过改变断面形状,取得了良好的支护效果。
Comblning the numerical simulation with engineering practice on E2--1305 work face of Liu zhuang Colliery, the coal roadway author has made a comparison of supporting effects with different cross--section shapes of bolting , and pointed out how to achieve a good supporting effect by changing the cross--section shape.
