Studies conducted on surface coal mining equipment have identified whole-body vibration as a significant hazard. Operators of underground mobile equipment, particularly shuttle cars and transport vehicles, are likely to be exposed to significant levels of whole-body vibration. To date, measuring whole-body vibration from underground mining mobile equipment has been difficult due to the strict g...

Underground coal gasification (UCG) is a conversion method that permits resources to be exploited in situ using high-temperature reactions. An understanding of the chemical, mineralogical, and petrographic properties coal, resultant unburned carbon, degasified ash (minerals) UCG zone, fundamental determining rates, gas composition, environmental groundwater risk assessments. This study aims pro...

The paper presents the aspects of 3D graphics utilization in the visualization of underground coal gasification (UCG) process. Data gathered during the process as well as achieved by the mathematical modelling describe a three dimensional structure of the georeactor where the process takes place. Proper visualization of this information is crucial for better understanding of the process and fur...

Yer altı kömür gazlaştırma (YKG) tekniği, geleneksel yöntemler ile üretilmeye uygun olmayan yataklarının değerlendirilmesi ve kömürden daha temiz yollarla enerji elde edilmesi amaçlarıyla uygulanmaktadır. YKG yüz yılı aşkın bir süredir gerek laboratuvar gerekse gerçek saha ölçeklerinde denenmiş literatüre çeşitli çalışmalar kazandırılmıştır. Bazı sahalarında pilot uygulamalar, bazılarındaysa ti...

The underground coal gasification (UCG) process represents a modern and effective mining technology that enables energy extraction through thermic decomposition. is transformed into syngas by oxidizers (e.g., air, technical oxygen, or water steam) injected georeactor. produced exhausted on the surface, where it desired form of energy. This paper presents an experimental study two experiments pe...
