| Abstract | We report the application of an infrared dual-wavelength laser absorption spectroscopy system, which combines tunable diode laser absorption spectroscopy and wavelength modulation integrated cavity output spectroscopy technologies based on two spectroscopic sources operating at 6,029 and 2,310 cm(-1), to simultaneously measure the gas concentrations (CH4 and CO2) and carbon isotopic signatures (C-13 and C-12) in coalbed methane. The Allan variance is used to analyze the optimum mean time (t) and the standard deviation (SD), with t=450s, SD=0.41 parts per thousand for (CH4)-C-13 monitoring and t=70s, SD=0.17 for (CO2)-C-13 monitoring. Furthermore, 47 groups of coalbed methane samples collected from the Huaibei-Qidong coal mine seam are analyzed based on the measured results for carbon isotopes and geophysical geochemistry. The delta(CH4)-C-13 values of the Qidong coal mine fall between -44.57 parts per thousand and -61.57 parts per thousand, and the delta(CO2)-C-13 values fall between -21.65 parts per thousand and -17.06 parts per thousand. The genetic types of methane may be divided into biogenic gas, thermogenic gas, and mixture gas. Carbon dioxide may be derived from coal pyrolysis, and it also has the characteristics of carbon-isotope changes of organic genetic gas. The new approach for analyzing rapid genetic types, methane migration pathways, gas disaster source warning, and coal chemistry studies is expected to be further studied in the future. Plain Language Summary In coal mine research, the measurement of carbon isotopic characteristics and the geochemical method have been found to be some of the most effective methods to identify the genesis, transport process, and source of coalbed methane (CBM). However, the application of carbon isotope measurement to gas outburst and transport in coal mines is still rare. Conventionally, the isotope has been determined by isotope ratio mass spectrometer measurements because of their high sensitivity and high accuracy, but its application range and frequency of sample analysis are severely limited because of its size, complex structure, high time consumption, sample collection, and complex preparation. In this paper, we introduce an infrared dual-wavelength laser absorption spectroscopy system, which combines tunable diode laser absorption spectroscopy and wavelength modulation integrated cavity output spectroscopy technologies based on two spectroscopic sources operating at 6,029 and 2,310cm(-1), to simultaneously measure the gas concentrations (CH4 and CO2) and carbon isotopic signatures (C-13 and C-12) in CBM. Furthermore, 47 groups of CBM samples collected from the Huaibei-Qidong coal mine seam are analyzed based on the measured results for carbon isotopes and geophysical geochemistry. The measurement results show good agreement with reference isotope ratio mass spectrometer measurements, confirming the accuracy of the proposed system. |
