摘要
阳煤集团三矿通过对竖井扩二区K8201工作面拆架期间采取注水、注氮、放置干冰、钻孔注水等防灭火措施,使该面在拆架期间各地点气体、温度都在规定范围内,保证了该面拆架期间的通风瓦斯安全,确认了综合防灭火技术对综采工作面拆架期间起到的作用和合理性。
Through taking fire prevention measures of water injection, nitrogen injection, dry ice placement and borehole water injection during the demolition of K8201 working face in the second expansion area of the shaft in No.3 Coal Mine of Yangquan Coal Group, the gas and temperature in all locations of the face during the demolition are within the prescribed range, which ensures the ventilation and gas safety during the demolition of the face, and confirmed the role and rationality of comprehensive fire prevention technology in the demolition period of fully mechanized mining face.
