Abstract: In order to reduce the influence of hydrogen sulfide gas on the main mining face, ensure the safety of working face personnel and mine efficiency, speed and safety production. Pulse hydrodynamic pressure injection of long and Short Boreholes for sulfur absorption is proposed. Based on the coal quality, occurrence characteristics and production conditions of 15# coal seam in Weishan Mine, this paper studies the abnormal situation of hydrogen sulfide germination in 15107 working face, and combines theoretical analysis and industrial test to study the long-short drilling pulse dynamic pressure injection alkali sulphur absorption. Mechanism; proposed the technology of long-short drilling pulse dynamic pressure injection alkali-sucking sulfur in Weishan Mine; formulated the hydrogen sulfide injection alkali-sulphur adsorption scheme of 15107 working face in Weishan Mine and carried out industrial test to effectively reduce the abnormal amount of hydrogen sulfide in the mine working face In the end, it achieved the goal of safe, high-yield and high-efficiency in Weishan Mine.
