[ 1 ] - Structural analysis of impacting factors of sustainable development in underground coal mining using DEMATEL method
Mining can become more sustainable by developing and integrating economic, environmental, and social components. Among the mining industries, coal mining requires paying a serious attention to the aspects of sustainable development. Therefore, in this work, we investigate the impacting factors involved in the sustainable development of underground coal mining from the structural viewpoint. For ...
[ 2 ] - Prediction of the main caving span in longwall mining using fuzzy MCDM technique and statistical method
Immediate roof caving in longwall mining is a complex dynamic process, and it is the core of numerous issues and challenges in this method. Hence, a reliable prediction of the strata behavior and its caving potential is imperative in the planning stage of a longwall project. The span of the main caving is the quantitative criterion that represents cavability. In this paper, two approaches are p...
[ 3 ] - Comparison of golden section search method and imperialist competitive algorithm for optimization cut-off grade- case study: Mine No. 1 of Golgohar
Optimization of the exploitation operation is one of the most important issues facing the mining engineers. Since several technical and economic parameters depend on the cut-off grade, optimization of this parameter is of particular importance. The aim of this optimization is to maximize the net present value (NPV). Since the objective function of this problem is non-linear, three methods can b...
[ 4 ] - تخمین گام تخریب اول بر اساس قابلیت تخریب لایه های سقف
اندازه گام تخریب اول در روش استخراج جبهه‌کار طولانی به طور مستقیم با بیشینه تنش وارد شده به تجهیزات نگهداری در ارتباط بوده و در نتیجه بر روی شرایط پایداری، ایمنی و تداوم عملیات مؤثر است. این مقاله برای تخمین گام تخریب اول رویکردی مبتنی بر قابلیت تخریب لایه-های سقف ارائه می‌کند. برای این منظور قابلیت تخریب سقف بلاواسطه از طریق تعریف شاخص قابلیت تخریب لایه‌های سقف (RSCi) با هدف تجمیع پارامترهای م...
