The performance prediction of roadheaders with response
Roadheaders are being used in development roads in underground mines. Especially, as total reserve is enough for large investments and mine roads, roadheaders are important to increase production rate. Roadheaders are classified according to the weight head drive or total power. In this study, the effects of several factors on roadheader performance is examined.

Roadheaders offer a unique capability and flexibility for the excavation of soft to medium strength rock formations, therefore, are widely used in underground mining and tunneling operations. A critical issue in successful roadheader application is the ability to develop accurate and reliable estimates of machine production capacity and the associated bit costs.

DEVELOPMENT OF A COMPUTER-BASED RISK ASSESSMENT
FOR UNDERGROUND COAL MINES Başayar Büyükkara, Fatma Nur M.S., Department of Mining Engineering Supervisor: Prof. Dr. Celal Karpuz February 2016, 138 pages Underground coal mining remains one of the worlds most hazardous occupations. There are numerous hazards in a mine, such as gas, dust, noise, temperature, and high humidity.
A fuzzy method for selecting underground coal mining
One of the crucial decisions affecting productivity of the mine is the mining method selection. Longwall mining is quite common in underground coal mining, and it allows the use of mechanization. As application of mechanization increases, production also increases and the number of workers decreases. Thus, the organization of work is easier, and the number of accidents decreases in the mine.
RISK ASSESSMENT BY FAULT TREE ANALYSIS OF METHANE
Mining is one of the most hazardous industries in the world. Among all mining professions, underground coal mining has the highest occupational accident and disease rates. Methane explosion appears as the major accident type which results in severe loss of life and property in underground coal mining.

Comparative studies on the performance of a roadheader
Mar 01, 2010· Drilling and blasting is the most widely used excavation method in mining and tunnelling especially in hard rock conditions. But in recent years, the application of roadheaders and impact hammers in hard rock, especially in fractured geological formations has increased considerably.
Mining - Underground mining Britannica
The principal means of access to an underground ore body is a vertical opening called a shaft. The shaft is excavated, or sunk, from the surface downward to a depth somewhat below the deepest planned mining horizon. At regular intervals along the shaft, horizontal openings called drifts are driven toward the ore body.
