Underground Coal Mining Methods and Engineering Dust
The two major underground methods are referred to as the room-and-pillar method and the longwall method. In both methods, the coal seam is developed by driving In the past few years, the mining industry has seen a lot of operational changes. Digitalization and automation of many processes have paved the way for an increase in its general productivity. In keeping with this trend, this article presents a novel approach for optimizing underground mine scheduling for the short- and medium-term. Short- and medium-term optimization of underground mine

A Review of Models and Algorithms for Surface-Underground Mining
It is important that the strategic mine plan makes optimum use of available resources and provides continuous quality ore to drive sustainable mining and profitability. This requires the development of a well-integrated strategy of mining options for surface and/or underground mining and their interactions. Understanding the current tools and Equipment failure is a common problem in mining operations, resulting in significant delays and reductions in production efficiency. To address this problem, this paper proposes a dynamic scheduling model for underground metal mines under equipment failure conditions. The model aims to minimize the impact of equipment failures on A Dynamic Scheduling Model for Underground Metal Mines

Advanced Analytics for Mining Method Selection SpringerLink
The approaches to mining method selection can be divided into three categories: methods of profile and checklist, methods of numerical ranking (scoring), and decision-making models [].Samimi Namin et al. [] presented a novel fuzzy multi-criteria decision-making model to select the mining method.For this reason, they introduced Production scheduling determines the most beneficial mining sequence over the life of a mine. Developing a schedule that meets all mining aspects can substantially reduce mining costs and increase profitability.

Selection of new appropriate mining method: case of
The selection of the adequate mining method is the cornerstone for mine planning and design. This selection depends on geological, geotechnical, economical, and environmental parameters. This paper’s main purpose is to select the most appropriate mining method for the south body of Boukhadra underground mine (NE Algeria). To do An underground vertical opening driven from an upper level downward is called a winze; this is an internal shaft. Mining Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, andMining Underground, Safety, Techniques Britannica

4.3.2: Underground Mining Methods. Underground mining methods become necessary when the stripping ratio becomes uneconomical, or occasionally when the surface use of the land would prohibit surface mining. Underground methods are traditionally broken into three classes: unsupported, supported, and caving methods.In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and overlying and underlying strata. Depillaring is one of the most Underground Coal Mining Methods and Their

Determination of the most appropriate tools of multi
Selecting the optimal mining method is one of the most critical issues in mining design. It entirely depends on different parameters, such as geotechnical, geological, economic, and geographic factors. Although many researchers have tried to apply a various multiple-criteria decision analysis (MCDA) technique to select the most appropriate In that case, underground mining methods are the only option. In addition, underground mining is assumed to leave fewer environmental impacts than surface mining . Among underground mining methods, block caving is the most cost-effective as it can produce 10,000–100,000 tons per day with a relative operating cost of USD 1 to 2.5 per Energies Free Full-Text Block Caving Mining Method
