This paper studied the toxicity and its mechanism of H₂ S and SO₂, carried research on the distribution of H₂S and SO₂ in coalbed gas and natural gas and related major problems, and analyzed and discussed the causticity and toxicity of H₂S and SO₂, along with related accidents, in exploration and the mining of natural gas and coalbed gas. The results strongly recommend that the content of H₂S and SO₂ be considered in coalbed gas areas for exploring and mining.  Initial research has suggested that the safety threshold value is approximately 0.0013% for H₂S, and 0. 036% for SO₂. Advanced research is in demand. In addition, the paleogeography deposition environment during the coal forming can serve as an index for selecting coalbed gas areas to explore and mine.
