为了採煤,人们不断地与水作斗争。人们开鑿煤井——水浸灌了巷道,使挖掘发生困难。许多地下的水流,也往往会冲破矿山岩层,进入地下矿藏,以致酿成大灾害。但是誰知道,在採煤方面,竟可以把水从敌人变成人们的忠实助手。 1952年12月在苏联库茲巴斯中心——普罗可利也夫斯基城,已经把水力採煤法“屠尔干斯基工作斜面”,应用於煤矿工业的矿井中。图书上表明的卽是这个矿井的内部情形。在矿井的横巷道里,我们看不见装煤机,电鑽或其他採煤的机器。这里也不需要爆炸,也不用小型贷车运煤。在离横巷道煤壁不远的地方,安装着水枪(射水机)。从它的长的圆锥形的枪管中,哗啦哗啦地,迸射出来一股高压水
In coal mining, people constantly struggle with water. People dig coal wells - flooding irrigation tunnels, making excavation difficult. Many underground streams of water often also break through the mine rock formations and enter underground deposits, causing major disasters. But who knows that coal mining can actually turn water from being an enemy into a loyal assistant to people? December 1952 At the Kuznets Center in the Soviet Union, Procuvievsky, the hydraulic coal mining method “Tulskansky slope” has been applied to the mines in the coal mining industry. The book shows the 卽 is the internal situation of the mine. We can not see a coal loader, an electric drill or any other coal-mining machine in the cross-country roadway. There is no need for an explosion here, nor does it require coal for small loans. In the place not far from the coal wall of the cross-roadway, a water gun (water jet) is installed. From its long conical barrel, crashed into a burst of high-pressure water
