摘要
以3103工作面大跨度切眼为研究对象,分析了传统架棚支护的利弊,提出采用'锚索网+托棚'和梯形棚交叉支护的方式进行切眼支护。结果表明,采用新支护方式能够加快切眼掘进施工速度,经济效益显著。
Taking the large-span cut-in of 3103 working face as the research object,the advantages and disadvantages of traditional roof support are analyzed,and the method of'anchor cable net+bracket'and trapezoidal roof cross support is proposed to support the cut-in.The results show that the new support method can accelerate the construction speed of the cut-in tunneling,and the economic benefit is remarkable.
