The waste dump is a giant artificial loose pile body composed of fine, medium, and coarse particle sizes. Rising incidents of landslides caused by overburden pressure and effective pressure are of increasing concern in the open-pit waste dump and, if not well-controlled, are a dangerous threat to the workers, the environment, and the equipment. The purpose of this research is to investigate the connection between effective pressure, porosity, void ratio, and coefficient of permeability and to find their influence in the open-pit waste dump. This study analyzed the mechanical and physical changes of seven different soil samples using consolidation and permeability under consolidation laboratory test. The test samples were subject to a pressure ranging from 100 to 1600 kPa. The effective pressure was found to play a major role in influencing void ratio, porosity, and coefficient of permeability, and waste dump height management and control are of great importance. This study answers the question regarding the correlation between effective pressure, void ratio, porosity, and coefficient of permeability in the open-pit waste dump. Further studies are needed to establish profound relationships and develop preventative measures to keep the waste dump slope stable and safe.

废料堆是一个巨大的人造松散桩体，由细，中和粗粒组成。由露天压力和有效压力引起的山体滑坡事故在露天垃圾场中引起越来越多的关注，如果控制不当，将对工人，环境和设备造成危险威胁。这项研究的目的是研究有效压力，孔隙率，孔隙率和渗透系数之间的关系，并找出它们在露天废物场中的影响。这项研究使用固结和渗透率在固结实验室测试下分析了七个不同土壤样品的机械和物理变化。测试样品承受的压力范围为100至1600 kPa。发现有效压力在影响空隙率，孔隙率和渗透系数方面起着主要作用，废物倾倒高度的管理和控制非常重要。这项研究回答了有关露天矿场中有效压力，空隙率，孔隙率和渗透系数之间的关系的问题。需要进一步研究以建立深远的关系并制定预防措施，以保持废物倾倒场的稳定和安全。
