沿复杂采空区综放开采过程中的综合防灭火技术应用实践
Application Practice of Comprehensive Fire Prevention Technology in Fully Mechanized Caving Along Complex Goaf

针对济宁市金桥煤矿分层开采采空区有害气体、下分层开采过程中漏风通道以及自然发火隐患等问题，基于金桥煤矿1306工作面开采工程现状，进一步明确了1306工作面火灾发生机理及预报方法，掌握了煤层自燃规律，并对1306工作面自然发火风险进行了科学分析，执行了有效的开采前、回采期间、开采后防灭火方案，保证1306工作面实现安全生产。开展沿复杂采空区综放开采过程中的综合防灭火技术应用实践项目后，1306工作面实现了安全顺利回采，真正实现了职工零伤害，生产秩序零影响，极大的鼓舞了井下工作人员的工作激情和信心，维护了矿井生产的稳定性，保证了矿井的和谐发展，创造了良好的社会效益。
In view of the problems such as harmful gas in the goaf of layered mining in Jinqiao Coal Mine, air leakage channel and hidden danger of spontaneous ignition in the process of lower layered mining in Jinqiao Coal Mine, based on the current situation of the mining project of 1306 working face in Jinqiao Coal Mine, the occurrence mechanism and prediction method of 1306 working face fire are further clarified, and the law of spontaneous combustion of coal seam is mastered. The risk of spontaneous ignition of 1306 working face is analyzed scientifically, and effective fire prevention and extinguishing schemes are implemented before, during and after mining to ensure the safe production of 1306 working face. After carrying out the comprehensive fire prevention technology application practice project in the process of fully mechanized caving along the complex goaf, the 1306 working face has realized safe and smooth mining, truly realizing zero injury to employees and zero impact on production order, greatly encouraging the work passion and confidence of underground workers, maintaining the stability of mine production and ensuring the harmonious development of the mine. It has created good social benefits.
