Parameter optimization of alkali injection prevention and field application in coal seam of high hydrogen sulfide roadway

Parameter optimization of alkali injection prevention and field application in coal seam of high hydrogen sulfide roadway

Exceeding the limit of underground hydrogen sulfide not only harms operators, but also damages underground equipment.The concentration of hydrogen sulfide in water in a coal mine roadway in Shanxi is 228.19 mg/m<sup>3</sup>, and 45.64 mg/m<sup>3</sup>in the air, rendering it...
