A method for predicting the hydrogen sulfide hazard of coal seams

This invention relates to the field of coal mine safety, specifically to a method for predicting the risk of hydrogen sulfide outbursts in coal seams. Currently, manual sampling for hydrogen sulfide gas detection in domestic mines is highly dangerous; furthermore, dissolved hydrogen sulfide is corrosive to mechanical measuring devices, resulting in low efficiency and the need for corrosion protection. This invention first determines the presence of geological water in the coal seam. If geological water is present, a small amount is deacidified and then tested with lead acetate test paper. If no geological water is present, a safe pH range is determined through mathematical statistics. While drilling into the coal seam at the measurement location in the tunneling face or return airway, the borehole flushing fluid is recovered, the pH value is measured, and the average value is calculated and compared with the safe pH range to determine whether there is a risk of hydrogen sulfide outbursts in the coal seam. This invention is highly practical in underground operations, highly safe, simple to operate, low in cost, and provides rapid and timely results, effectively ensuring the safety of underground workers and the safe and efficient production of coal mines.
