摘要
根据锚网索联合支护技术特点及3205回风顺槽工程概况,应用临时支护、锚网索联合支护方式进行大断面回采巷道支护,并建立矿压观测。观测和实践结果表明,锚网索联合支护技术适用于大断面煤巷的掘进,该技术已在王坡煤矿其它采准巷道得到了广泛应用,为安全生产提供了可靠保障,并取得了良好的经济、社会效益。
According to the features of bolt- mesh- anchor combined supporting and the project profile of No.3205 return air crossheading, temporary support and the bolt- mesh- anchor combined supporting are used in the large cross- section roadways. By mine pressure observation, the results show that the combined supporting is applicable to the large cross- section roadway driving. The technology has been widely used in other roadways of Wangpo Mine and, which could provide reliability for safety production and has achieved ideal economic and social benefits.
