Coal mining in India has a history of over 225 years. The industry currently occupies a covetable third ranking in the world league table of hard coal production after China and the USA. Mechanization has made possible major breakthroughs in coal mining technology. The record of production and productivity of Indian underground coal mines over the years is dismal, to say the least. At the time ...

The paper presents some theoretical considerations regarding the evaluation of the underground mining constructions ' stability and practical aspects about identifying experimentally the d} •natnic regime of the pressure . The identification represents an experimental technique to determinate the dynamic models of the process , an important stage in designing and implementing an elastic perform...

PROBLEM Mining in the United States remains one of the most hazardous industries, despite significant reductions in fatal injury rates over the last century. Coal mine fatality rates, for example, have dropped almost a thousand-fold since their peak in 1908. While incidence rates are very important indicators, lost worktime measures offer an alternative metric for evaluating job safety and heal...

Multi-criteria decision-making methods are widely used to solve various problems in the industry, as well support planning and designing industrial processes. Mining is a very complex responsible activity, so when making major decision, it necessary take into account several parameters perform their detailed analysis. Due importance of proper decision making, multi-criteria optimization have wi...

This paper describes the design, implementation, and field testing of an infrastructureless system for autonomous tramming (or hauling) of a center-articulated underground mining vehicle. Described is the development of a fast, reliable , and robust " autotramming " technology that does not require the installation of fixed infrastructure throughout the mine.

Roadheaders are one of the most popular mechanized excavators used in mining and civil underground construction. These machines are primarily used in soft to medium hard rocks. This paper reviews the parameters associated with the application and operation of roadheaders and presents a method for estimating cutting performance.

At present, the cooling of all the hot underground operations at Impala is achieved by providing refrigerated air from surface. However, the depth of a number of planned projects will approach 2 000 m below surface and other future proposed operations will extend to even deeper levels. Obviously these depths will approach the horizon where acceptable underground conditions can no longer be achi...

Rock engineering constructions are widely attested in energy mining, geothermal development, and underground storage projects [...]

Belt conveyors are presently the most common transportation machines used in surface and underground mining [...]
