摘要
调研了我国煤矿火灾灾害区域分布特点及近5年来煤矿火灾事故特征,从自燃倾向性鉴定、自然发火期判定、自然发火早期预测预报及监测等方面探讨了煤自燃预测预报技术的发展现状,分析了现阶段我国充填堵漏、均压、注浆、惰性气体、阻化、三相泡沫、燃油惰气及高倍泡沫等防灭火技术装备的应用现状及适用性。指出煤矿火灾防治应坚持以基础理论研究为先导,以关键技术装备研发为重点,以推广应用为目的,不断创新提高防火技术的有效性、适应性和经济性,以指导煤层自燃与外因火灾防治,最终实现一体化火灾防控体系的技术突破。
The regional distributions features and the past five years accidents characteristics were investigated about mine fire accidents in China.The current situation of coal combustion forecast and prediction technologies were discussed from three aspects of identification of spontaneous combustion tendency,determination of spontaneous combustion period and monitoring of initial coal spontaneous combustion.The application status and suitability of different mine fire prevention & extinguishing technologies were analyzed,such as filling leakage,pressure balance,grouting,inert gases,inhibitor,three-phase foam,high-expansion foam and polymer materials.Finally,the authors put forward that the realization of integrated mine fire prevention & extinguishing system should persistent in the foundation theories research as the basis R&D of technologies and equipments as the key,the promoting of advanced technologies as target,aiming at improving the effectiveness,adaptation and economy of coal mine fire prevention and extinguishing technologies,which could provide the references for coal seam combustion and mine fire prevention induced by external cause.
