摘要/Abstract

摘要： 为提高拉斗铲作业效率，针对黑岱沟露天矿8750型拉斗铲的作业循环耗时进行了统计研究。结果表明：挖掘方式、岩土台阶几何形状是影响挖掘效率的主要因素，提出组合式挖掘、改变岩土局部几何形状提高设备挖掘环节效率；设备转动耗时是影响一次作业循环效率的主要因素，提出满载旋转、空载返回环节中，应保持设备加速、减速过程中转动角度的比值分别为3/2，4/5；铲斗提升耗时是制约挖掘煤沟作业效率的关键因素，根据“提升-旋转”制约关系制定了拉斗铲挖掘-排弃位置参考表。

Abstract: In order to improve the efficiency of dragline operation，statistical study has been made on time consuming of dragline single-operation cycle in Heidaigou surface mine. The results have shown that mining methods and geometry of soil bench are the main influence factors of digging efficiency and put forward combined-type digging and changed partial geometry shape of soil in order to improve digging efficiency. Time consuming of equipment rotation is the main factor that influence the efficiency of single operation cycle, so rotation angle ratio of acceleration and deceleration process should be 3/2 in rotating and 4/5 in returning step respectively. Time consuming of bucket ascension is the key factor which restricts the efficiency of coal trench excavation. Reference table of dragline operation has been made according to the restrictive relation between bucket ascension and equipment rotation.

Key words: dragline, overcast stripping, circulating time, operational efficiency
