Semi mobile in-pit crushing and conveying systems have different pit shape requirements to traditional truck haulage systems due to the inclusion of a conveyor flight in the pit. As the shape of a pit is heavily influenced by the ultimate pit limit, it is desirable to have the additional shape requirements included in the ultimate pit limit determination process. This paper introduces in-pit crushing and conveying systems and discusses their differences and benefits. The differences and requirements of pit design between truck haulage and semi mobile in-pit crushing and conveying systems are then highlighted. A method of including the additional requirements during the ultimate pit limit determination is presented. A case study has been included that shows the method working successfully, with scheduling of the pits to further highlight semi mobile in-pit crushing and conveying viability. This case study shows that through the reduced mining costs, a semi mobile in-pit crushing and conveying pit can return a higher Net Present Value, despite being smaller than the traditional truck and shovel pit for the same deposit. The development of this method provides the opportunity for the metalliferous industry to accurately determine ultimate pit limits for a mines considering the use of semi mobile in-pit crushing and conveying systems.

半移动式坑内破碎和输送系统与传统的卡车拖运系统相比，对坑道的形状要求有所不同，这是因为在坑道中包含了一条传送带。由于凹坑的形状在很大程度上受最终凹坑极限的影响，因此希望在最终凹坑极限确定过程中包括其他形状要求。本文介绍了坑内破碎和输送系统，并讨论了它们的区别和好处。然后重点介绍了卡车运输和半移动式矿山破碎与输送系统之间矿山设计的差异和要求。提出了一种在最终矿坑极限确定过程中包括其他要求的方法。包含的案例研究表明该方法成功运行，安排矿井，以进一步突出半移动矿井的破碎和输送可行性。该案例研究表明，通过减少采矿成本，半移动式矿山破碎和运输矿井尽管具有相同的沉积物，却比传统的卡车和铁锹矿井小，但其净现值却更高。这种方法的发展为金属工业提供了机会，可以考虑使用半移动式坑内破碎和输送系统来准确确定矿山的极限坑极限。
