一、前言 煤炭工业部门早就认识到,在采煤工作面需要一种能够实现连续运输的设备。三十多年前,人们把一些连续运输系统首次应用到矿井的生产中,但当时仅有几套使用是成功的。直到七十年代初,连续运输系统才得到了进一步改进和完善。目前,可从许多制造厂家购到各种连续运输系统,但该系统尚未被人们所接受,故没能得到广泛应用。随着人们在煤炭生产中的不断探索,连续运输系统必定会赢得广大用户的青睐。 I. INTRODUCTION The coal industry sector has long recognized that there is a need for a piece of equipment capable of continuous transport at the coalface. More than 30 years ago, some continuous transportation systems were first applied to the production of mines, but only a few sets were successful at that time. Until the early 1970s, continuous transport system was further improved and perfected. At present, a variety of continuous transport systems are available from many manufacturers, but the system has not yet been accepted by the public and thus has not been widely used. As people continue to explore the production of coal, continuous transport system will win the majority of users of all ages.
