摘要

本文研究了最佳实用的挖掘弃土顺序，该顺序可以解决弃土堆中的圆形破坏，并通过提高煤炭暴露率来提高生产率。这包括通过DragSim软件和MS Excel拉铲计算器评估两个上手式切碎和三个推土机推土铲挖掘弃土序列。该软件为岩土工程分析提供了弃土剖面图，计算器生成了生产力指标（挖掘率、煤炭暴露率和再处理百分比）。根据满足矿山预算要求的能力以及稳定性和生产力的最佳实践标准对序列进行了排名。最实用的挖掘弃土顺序是倾斜弃土侧推土机推覆顺序。建议将B坑分为两半：分别在上半部分和下半部分采用改良的上手铲和倾斜弃土侧推土机推土顺序。

Enhancing productivity through effective spoil stability management in an open cast coal mine

The paper investigated the best practical dig-spoil sequence which addressed circular failure in waste spoil piles and enhanced productivity through an improved coal exposure rate. This involved the evaluation of two overhand-chop and three dozer pushover dig-spoil sequences through DragSim software and an MS Excel dragline calculator. The software provided spoil profiles for geotechnical analysis and the calculator generated productivity indicators (digging rate, coal exposure rate and rehandle percentage). The sequences were ranked in terms of the ability to meet the mine budget requirements and best practice standards for stability and productivity. The best practical dig-spoil sequence was the oblique spoil-side dozer pushover sequence. It was recommended that Pit B be split in two halves: a modified overhand-chop and oblique spoil-side dozer pushover sequence for the first and second half, respectively.
