战后以来瑞典的采矿工业获得了迅速的发展。本文介绍各项采矿作业的一般情况。在瑞典矿山,冲击式凿岩是钻凿坚硬岩石的主要方法。凿岩机逐渐得到改进;以每分钟凿碎岩石体积计算的凿岩生产率在短时间内几乎增加了三倍(图1)。借助有效的钻架,能使凿岩机更有效地得到利用,凿岩机安在钻架上,可使操作机械化并容易定线,且使一个工人有可能操作二台或更多台凿岩机,从而节约了人力。 Sweden’s mining industry has enjoyed rapid growth since the war. This article describes the general situation of various mining operations. At Swedish mines, rock drilling is the main method of drilling hard rock. Rock drills have been gradually improved; rock productivity, calculated in terms of rock mass per minute, has almost tripled in a short period of time (Figure 1). Drilling rigs can be used more effectively with the help of an effective drill rig, which can be manipulated and easily routed while drilling one or more rock drills to save labor. .
