Types of Underground Mining Method Comparison

In any discussion of Methods of Underground Mining Comparison one is repeatedly confronted with the difficulty of dealing with so many variable conditions. It is not an exact science and in the choice of a method each varying factor has a certain weight which in many cases experience alone can determine. In mathematical terms it is a

Intelligent Mining Technology for an Underground Metal

As shown in Fig. 3 the executive layer mainly consists of trackless mining equipment such as rock-drilling jumbos DTH drills underground scrapers underground mining trucks or underground charging vehicles.The transport layer mainly includes a ubiquitous information-acquisition system wireless communication system and precise positioning and intelligent navigation system.

CORE

As the mining depth increase the technical challenges and difficulty to retrieve resources rises. The future deep level mining environment is considered too immense a risk for human labour. Therefore robot technology is considered as an alternative. This imposes the need to develop and improve current mining technology and equipment.

mechanized mining operations have reduced to about one-third of those 50 years ago. The biggest obstacle to lower cost and safer mining in narrow-reef orebodies typical of the gold platinum and chrome mines found in southern Africa is the blasting cycle with its inherent poor utilization of the mining assets. In conventional mining
