Gasifikasi batubara bawah tanah adalah proses gasifikasi secara in-situ pada lapisan yang jauh di dengan cara melakukan injeksi udara bertekanan melalui sumur bor dan menghasilkan gas bakar produksi. Salah satu permasalahan perlu diperhatikan dalam ini kerusakan konstruksi saat menginjeksikan ke sumur, ketika akan membuat jalur koneksi antara Beberapa faktor dievaluasi tegangan regangan maksimu...

Underground coal gasification (UCG) is a clean mining technology without significant environmental impacts. This can also be used in deep, hard-to-reach seams or deposits affected by tectonic disturbances, where conventional impossible. Several techniques and methods have been investigated worldwide to support the process control of UCG. Global research focuses on UCG operating parameters stabi...

Purpose Underground coal gasification is a very difficult process due to changes in the parameters over time and within space of reactor variety phenomena that occurs there. Consequently, it necessary create appropriate mathematical models, which simplify optimization forecast future results (especially final gas properties). The purpose this work was detailed critical analysis simplest simulat...

Many coal mine companies have established underground safety monitor and control systems. However, the safety management information can only be displayed on the 2D maps or as reports. In this paper, a new method that combines the VR technologies with underground mine safety monitoring technologies was explored. A desktop virtual reality program for underground coal mine, called VRLane, was dev...
