摘要
目前在许多设置专用钻孔为避险硐室供氧的煤矿中,钻孔孔径一般都比较小,仅能布置供水、供氧、供电及通讯管路(线),无法直接进行人员的营救工作,针对这一现象,提出了大孔径地面专用钻孔在煤矿紧急避险系统中的应用技术。大孔径地面专用钻孔除了能满足基本生存保障功能外,还能作为应急逃生安全出口,提高煤矿紧急避险系统的功能。
At present, diameter of special drilling of supplying oxygen in Hedging chamber is normally small, only with function of water and oxygen supply, power supply and communication line, without the function of rescuing people directly,based on this problem, technology of large diameter ground special drilling in mine emergency system was put forward. The technology could meet the basic survival guarantee need, and be the emergency exit and improve the functions of mine emergency system.
