High quality carbon steel for deep drawing (GJB 163-86)
Carbon Steel
Carbon Steel is a type of steel alloy composed of iron and various other elements, such as carbon. Carbon steel is one of the most important types of steel alloys used in a variety of industries. The presence of carbon in steel gives it high strength and hardness, making it a very us......
Underground Mine Transportation Design
Underground mining transport design
Underground mining is an inherently dangerous process. It requires strict safety practices and protocols in order to protect workers, reduce risk, and ensure operations are as efficient as possible. Underground mining transport is a crucial element of this proc......
Design of moving range for underground mine mining
Introduction
Underground mining is a process in which minerals are extracted from beneath the earth by tunneling and cutting away from above. It requires expertise, planning and safety considerations in order to ensure that the excavation is carried out properly and efficiently. This paper will d......
Underground Mine Filling System Design
Design of Underground Mine Backfill System
Backfilling has been widely used in underground mining around the world for decades. This method of support not only increases the stability of the mine, but also improves the work environment. The traditional backfilling method is to manually backfill c......

Underground Mining Methods
Introduction
Underground mining is the process of extracting minerals and ores from underground. Underground mining has been around for centuries and though the mining techniques have changed drastically over the years, the idea is still largely unchanged. Underground ......
Open-pit development of ore deposits
Open-pit Mining
Open-pit mining, also known as open-cut mining or opencast mining, is a surface mining technique used to extract a near surface deposit of mineral resources. This form of mining differs from extractive methods that require tunneling into the earth, such as longwall or room-and-pil......
Underground engineering reverse method
Underground construction is the process of creating a functional and safe underground environment to provide services associated with construction activities. Underground construction work involves much hazardous work, such as tunneling, drilling, and masonry, and typically requires advanced skill......
Wettability of Mineral Surfaces
Wettability of Mineral Surfaces
Introduction
Mineral wetting is an important and complex phenomenon related to the interactions between a solid surface, liquids, and gas phases. The wettability of a mineral surface is defined as its ability to spread and form a thermodynamically stable interface......
