一、前言近年来,随着耐压胶管、衬垫等的发展,高速水射流在各个领域(土建、矿业、机械、汽车、食品、纤维、医药等)盛行了起来。可是,日本矿山的现状是,除了水力采煤以外其它方面都没怎么用。本研究室从几年前就考虑了高速水射流在矿山的应用,作为开始,现在在赤平煤矿进行的大直径钻孔上试用了高速水射流。

I. Introduction In recent years, with the development of pressure-resistant hoses and gaskets, high-speed water jets are prevalent in various fields (civil engineering, mining, machinery, automobile, food, fiber, medicine, etc.) However, the status quo of Japanese mines is that they have not used anything else except for hydraulic coal mining. Our laboratory considered the application of high-speed water jets in mines a few years ago. As a start, high-speed water jets were now piloted at large-diameter boreholes in the Chiping Coal Mine.
