大采高综采工作面综合防灭火技术应用探讨

Discussion on the Application of the Integrated Fire-Extinguishing Technology in Full-Mechanized Mining Face with Large Mining Height

对大采高综采工作面综合防灭火技术应用的研究,首先要明确工作面综合防灭火技术体系的主要构成,然后与其中内容相结合,对大采高综采工作面应用综合防灭火技术的策略进行分析。得出自燃发火预测预报技术,针对遗煤氧化进行抑制的技术,预防性注氮、注浆技术与注二氧化碳技术,喷洒阻化剂技术以及裂隙带钻孔注水技术这七点主要内容,总体实现了大采高综采工作面综合防灭火技术应用的高效化,希望能够为有关人士提供帮助。

In order to study the application of the integrated fire-extinguishing technology in full-mechanized mining face with large mining height,the main composition of the comprehensive fire prevention and extinguishing technology system in working face should be defined first.And then combined with the content of it,the paper analyzes the strategies of applying the integrated fire-extinguishing technology in full-mechanized mining face with large mining height.Prediction technology of spontaneous combustion,technology of inhibiting oxidation of residual coal,preventive nitrogen injection,grouting technology and carbon dioxide injection technology,spraying inhibitor technology and borehole water injection technology in fractured zone are obtained.The high efficiency application of the integrated fire-extinguishing technology in full-mechanized mining face with large mining height has been realized in general,and it is hoped that this technology can provide help for relevant personnel.
