摘要
拉斗铲倒堆剥离是一种先进的开采工艺,机械化程度高,开采成本低。论文对世界范围倒堆剥离用大型拉斗电铲的使用现状做了统计分析,介绍了拉斗铲倒堆剥离工艺特点及拉斗铲的基本作业方式,分析了我国大型煤田采用倒堆剥离方法的有利条件及应用前景。
The open cast method is an advanced stripping technology with low operation cost. The manufacture and application of draglines in the world were summarized, the operation methods of draglines were introduced, and the favorable conditions of large coal fields in China and the application prospect forth is open cast method were analyzed.
