Considering the various hazards present in an underground mine, safe ventilation entails maintaining a certain airflow rate mining workings. The air velocity, and composition must be regulated network by operation of main fans. On other hand, costs minimized. Thus, optimal solution is when requisite safety features are fulfilled power output fans at minimal yet sufficient rate. In real-world mi...

in advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. the gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (edz) above the gate roadway and 2) loading effect due to the caving zone (cz) above the longwall w...

In this study based on image analysis, an ore grade estimation model was developed. The study was performed at a limestone mine in central Iran. The samples were collected from different parts of the mine and crushed in size from 2.58 cm down to 15 cm. The images of the samples were taken in appropriate environment and processed. A total of 76 features were extracted from the identified rock sa...

Mine Safety and Health Administration (MSHA) regulations require underground coal mines to use refuge alternatives (RAs) to provide a breathable air environment for 96 hrs. One of the main concerns with the use of mobile RAs is the heat and humidity buildup inside the RA. The accumulation of heat and humidity can result in miners suffering heat stress or even death. To investigate this issue, t...
