江苏省煤矿研究所研制的6000公斤/厘米冲击式发生装置在半煤岩巷道掘进已取得显著效果。这种装置是靠蓄能装置(发生器)蓄能,在极短的时间内以高动能的水发射出去,从而产生高压水射流(又称水弹)进行破岩落煤。这就给巷道掘进提供了新的方法——水泡掘进。
The 6000Kg / cm impact device developed by Jiangsu Coal Research Institute has achieved remarkable results in semi-coal and rock roadway driving. This device is based on energy storage device (generator) storage, in a very short period of time with high kinetic energy of water emitted, resulting in high-pressure water jet (also known as water bomb) rock breaking coal. This provides a new way for tunneling - blistering.
