我国露天煤矿开采工艺发展状况综述

On Development of Surface Coal Mining Systems in China

文章简要介绍了我国露天开采工艺的发展过程,建国初期主要以単斗铁道工艺为主发展至1980年代以来转向以単斗汽车工艺为主,半连续开采工艺、综合开采工艺、拉斗铲倒堆工艺等目前各种露天开采主流工艺并存局面的特点和采用的主要采掘、运输设备.介绍了当前我国露天煤矿开采工艺的主要特点、发展状况以及存在的主要问题.

The development of surface mining systems is briefly introduced. Since the foundation of the People＇s Republic of China in 1949, the shovel/train system have been used as the major surface coal mining system. From 1980s on, the surface coal mining systems in China have been becoming combinations of shovel/truck, semi-continuous mining system in combination with mining systems and dragline stripping. The main digging and hauling equipment used in present mining systems are also summarized. After describing the main characteristics and development in China＇s surface coal mining systems, the major problems faced are also pointed out.
