英国皮克罗斯有限公司卡多克斯分公司(The Cardox Division of Pikrose and Compang Ltd of the UK)采用一种无炸药爆破的方法。主要设施是一根内装有压二氧化碳的钢管。爆破时,把钢管放入预先钻好的孔中,然后将孔口封住,以防引爆时管子射出。爆破采用电引爆。二氧化碳不属于炸药类,它不象传统的爆破方法那样产生冲击波。这种方法适用于宜径为1～10m的隧洞。 The Cardox Division of Pikrose and Compang Ltd of the UK used a method of explosive-free blasting. The main facility is a steel tube with pressurized carbon dioxide. When blasting, put the steel pipe into a pre-drilled hole, and then seal the hole to prevent the pipe from being ejected when the pipe is detonated. Explosion using electric detonation. Carbon dioxide, which is not a type of explosive, does not create a shock wave as the traditional method of blasting. This method is suitable for tunnels with a diameter of 1 ~ 10m.
