采空区注浆防灭火技术研究

Study on Grouting Fire Prevention Technology in Goaf

以阳泉南庄矿井为研究对象,对其采空区注浆防灭火技术进行研究。根据其地质条件进行了煤层自然发火期的测定,采用数值模拟技术对工作面采空区自燃“三带”分布进行了划分与建模,依照上述研究确定了采空区的注浆方案,并阐述了注浆的过程,为南庄煤矿的井下安全生产提供保障。

Taking Yangquan Nanzhuang Coal Mine as the research object,the research on grouting fire prevention technology in goaf was carried out.According to its geological conditions,the spontaneous combustion period of coal seams was determined,the"three zones"distribution of spontaneous combustion in the goaf of the working face was divided and modeled using numerical simulation technology,the grouting scheme of the goaf was determined according to the above research,and the grouting process was described,which provided a guarantee for the underground safety production of Nanzhuang coal mine.
