一、前言 日本政府委托煤炭技术研究所研究喷射作业机械化和采用高效喷射材料运输系统,来改善煤矿喷射混凝土的施工方法,以及使井下重要场所的巷道具有防火性能,以防止因自然发火而引起井下的火灾,包括骨料的集装箱运输系统、远距离操纵式喷射机械手及水泥散装运输系统三部分。在太平洋煤矿已进行了井下试验,本文只介绍喷射机械手与水泥散装运输两部分。
I. Introduction The Japanese government has commissioned the Institute of Coal Technology to study the mechanization of jetting operations and the use of highly efficient jetting material transport systems to improve the construction methods of coal mine shotcrete and to make the tunnels of important places underground fireproof to prevent downhole Of the fire, including aggregate container transport system, long-distance operation of jet robot and cement bulk transport system in three parts. Mine has been carried out in the Pacific Mine test, this article only describes the jet manipulator and bulk cement transport in two parts.
