Abstract:
The most common explosive gases in coal mines include methane CH2, hydrogen sulfide (H2S), hydrogen (H2), and carbon monoxide (CO) gases [1]. Most of Iran s coal mines are low gaseous since they operate in low to moderate depths. This leads to classify these mines in the most dangerous classes. If the mine is highly gaseous or be in gassy condition always, then people working in the mine will consider the problems accurately and carry out extraction operations cautiously, but if the amount of gasification is low, they will ignore the risk. In our country, due to the high daily providence and maintenance cost of chemical sensors, is has not been used any sensor in small mines with a maximum depth of three kilometers and they are classified as non-gassy mines. This paper aims to propose a real-time sensor having low cost without any consumable materials that can be used by all mines. Photonic crystal waveguide sensors have very small dimensions. Also, since these structures work with the light, they will alert the central automation systems as real time. Also, these structures do not have any consumable materials and can be used without interruption for long periods without maintenance [2].
