摘要
为了更好地做好综放工作面的末采及撤除期间的防灭火工作,通过对煤层自然发火期和防灭火方法的分析,提出了采用注氮、注浆、注胶、注阻化剂等多种措施结合的方式解决煤层易自燃问题。实践表明,多种方式结合的综合防灭火技术确保了工作面的正常撤除。
In order to do a better job of fire prevention in the end and removal period of fully-mechanized top coal caving face,through the analysis on the spontaneous combustion period of coal seam and fire prevention method,relevant method was proposed to solve the spontaneous combustion problems of coal seam comprehensively using nitrogen injection,grouting,plastic injection,inhibitor injection,and so on.Practices show that,this comprehensive fire prevention technology ensured the normal removal of the working face.
