摘要
以华融龙宫矿22103综采工作面切眼的锚杆形式为背景,悬吊组合梁理论为基础,根据切眼实际工况,采用综掘机一次成巷。利用锚杆、锚索、钢带、单体液压支柱协同的方式,对顶板岩层进行组合支护,并从施工安全、技术可行、经济效益方面分析评价综采切眼支护技术的优越性,其成果有一定参考价值。
Taking bolts of 22103 working face in Longgong mine as study background, suspension beams principle as foundation, tunneling by fully-excavating machine was adopted according to the actual situation of open-off cut. The bolts, cables, steel belts, and single hydraulic props were combined to support the roof strata. The open-off cut technology was evaluated in terms of construction safety, technological feasibility, and economic benefits. The result is useful for similar conditions.
