100多年来,钻爆法在硬岩洞室开挖中一直占主导地位。这种施工方法的要点就是用凿岩机打眼,用炸药爆破岩石。为了提高凿岩的效率,国外从六十年代以来一方面研制新型凿岩台车或钻车,一方面研制新型凿岩机具。到目前为止,风动凿岩机的发展已达 For more than 100 years, the drill-and-blast method has dominated the excavation of hard rock caverns. The key point of this method of construction is to drill a hole with a rock drill and blast the rock with explosives. In order to improve the efficiency of rock drilling, foreign countries from the 1960s on the one hand, the development of new drilling rigs or drilling vehicles, on the one hand the development of new drilling equipment. So far, the development of pneumatic rock drills has reached
