随着南屯矿矿井采场面积的不断扩大,开采深度加强,采空区面积扩大,大面积采空区连成一片,使得因采空区漏风造成的瓦斯涌出和煤炭自燃隐患更加突出。在分析采空区漏风特点及规律基础上,介绍了采空区漏风的监测方法,针对区域性和局部漏风控制提出相应的措施,优化了通风系统,有效的控制了漏风,保证了矿井安全生产。
With the continuous expansion of the stope area in Nantun Mine, the mining depth has been strengthened. The area of the goaf has been enlarged and the large-area goafs have become one. This makes the gas emission caused by the air leakage in the goaf and the potential of coal spontaneous combustion become more prominent. Based on the analysis of the characteristics and rules of air leakage in goaf, this paper introduces the monitoring method of air leakage in goaf, puts forward corresponding measures according to the regional and local air leakage control, optimizes the ventilation system, effectively controls the air leakage and ensures the mine safety production .
