超前路堤排土机双向排土方式研究

Research on bidirectional dumping process for overfill embankment with pusher-type dumper

传统的排土机矩形和扇形排土方式运用于不规则形态排土场中,将造成移置次数多。为提高排土机作业效率,降低排岩成本,本文以攀枝花新白马铁矿某排土场为例,从排土场形态特点出发,提出超前路堤排土机双向排土新方式,对新旧排土方式从单次排土量、移置次数及运营成本等多方面进行对比,论证在针对狭长型排土场的条件下超前路堤排土机双向排土方式的优越性。针对地形条件复杂,用地形状不规则的排土场,根据排土机移置特点,提出超前路堤排土机双向排土工艺,分析该工艺的单次排土量、移置次数及运营成本优势,为排土机排土提供传统排土方式之外的另一种选择。

The traditional waste methods of rectangular and fan-shaped arrangements applied to irregular-shaped waste dump result in multiple relocation operations.In order to enhance the efficiency of dumping machines operations and reduce rock dumping costs,this paper takes a specific waste dump at Panzhihua Xinhua Baima Iron Mine as an example.Starting from the characteristics of the waste dump's morphology,it proposes a new approach of forward embankment for dumping machines bidirectional dumping is proposed.A comprehensive comparison is made between the new and old dumping methods in terms of single dumping volume,number of relocations,and operational costs,thereby validating the superiority of the forward embankment for dumping machines bidirectional dumping for narrow and elongated waste dump.According to the characteristics of the displacement of waste dump,this paper proposed a bidirectional dumping process for overfill embankment with dumping machines,and analyzed the advantages of single dumping volume,displacement times and operation cost of the process.It provided an alternative to the traditional dumping method for waste dump.
