Abstract:

The mineral processing industry faces significant environmental challenges in tailings management, necessitating innovative approaches to waste reduction and resource efficiency. This study examines the systematic application of Lean Project Management (LPM) methodologies in mineral processing operations to address these challenges. The research demonstrates the effectiveness of LPM principles in reducing waste and minimizing environmental impacts while maintaining operational efficiency. The methodology incorporates value stream mapping, 5S implementation, and continuous improvement processes to analyze mineral processing workflows. Through systematic evaluation of operational processes, the study identifies critical waste sources and inefficiencies in tailings management. The research employs quantitative metrics to assess environmental impact reduction and resource recovery improvements. The implementation framework includes comprehensive stakeholder engagement strategies and regulatory compliance measures. The results demonstrate significant improvements in tailings management efficiency through LPM implementation. Key findings include enhanced resource recovery rates, reduced environmental contamination risks, and improved operational cost-effectiveness. The study reveals that systematic application of LPM principles leads to measurable reductions in both material waste and process inefficiencies. Furthermore, the research establishes a correlation between improved tailings management practices and enhanced community safety outcomes. The study contributes to the development of industry best practices by providing a structured approach to integrating LPM principles into mineral processing operations. The findings indicate that the LPM methodology effectively balances environmental protection with operational efficiency while generating additional economic value through improved resource utilization. This research establishes a framework for sustainable mining practices that address both environmental concerns and operational requirements, offering valuable insights for industry practitioners seeking to enhance their environmental performance while maintaining economic viability.

Abstract:

In order to study the effect of conservative tillage on a number of physical properties of soil and the yield of rainfed wheat, an experiment in the form of a randomized complete block design (RCBD) with three replications was conducted in a field in Aliabad County, Iran. The study treatments included: T1) Conventional method, T2) Combined moldboard plow method, T3) Chisel-packer method, and T4) Direct planting method. During early October, the study soil was prepared based on these treatments in a field which was used for rainfed wheat farming in the previous year. The apparent specific gravity of soil, weighted mean diameter (WMD) of soil aggregates, soil mechanical resistance, and soil permeability were measured. Data were analyzed in MSTAT-C. Results showed that the tillage practice had no significant effect on grain yield (p < 0.05). Soil permeability was 10.9, 16.3, 15.7 and 17.9 mm/h for T1, T2, T3 and T4, respectively.

Abstract:

Static stability of soil slopes using numerical simulation by a finite element code, ABAQUS, has been investigated, and safety factors of the slopes achieved in the case of static load of a 10-storey building. The embankments have the same soil condition but different loading distance from the slope heel. The numerical method for estimating safety factors is 'Strength Reduction Method' (SRM). Mohr-Coulomb criterion used in the numerical simulations. Two steps used for measuring the safety factors of the slopes: first is under gravity loading, and the second is under static loading of a building near the slope heel. These safety factors measured from SRM, are compared with the values from Limit Equilibrium Method, LEM. Results show that there is good agreement between SRM and LEM. Also, it is seen that by increasing the distance from slope heel, safety factors increases.
