Abstract: In view of the problem of the large amount of hydrogen sulfide emitted during coal cutting in the stoping face, the working face is designed and constructed with multi-row cluster drilling and alkali injection for interception, and appropriate lead distance is set between adjacent areas, and multi-row intercepting boreholes are formed to form 3 rows of hydrogen sulfide intercepting areas. After the reaction between lye and the adsorbed hydrogen sulfide gas in the coal body, it can intercept the hydrogen sulfide in advance, so that the hydrogen sulfide in the coal body can be absorbed by the lye before the coal cutting, thus reducing the emission of hydrogen sulfide during the coal cutting. Practice shows that the multi-row cluster drilling has the function of intercepting hydrogen sulfide. The average concentration of hydrogen sulfide in the return airway is reduced by 61.32%.
