上覆火区影响下的综采工作面均压通风防灭火技术

Ventilation and fire prevention technology in fully mechanized coal mining face under the influence of the overlying fire

通过分析苏海图煤矿031502综采工作面均压风量设计计算,得出可满足通风要求的风量取432m3/min;经过均压通风防灭火技术的实施、调试以及实施过程中应该注意的相关事项和对实施均压通风技术前后的效果进行了分析比较,结果表明:均压通风技术在治理采空区漏风方面效果是显著的,可以起到防灭火效果,确保了综采工作面的安全生产。

Through the analysis of Su Haitu coal mine 031502 fully mechanized coal face all pressure airflow design and calculation, it is concluded that can meet the requirements of ventilation air volume of 432m^3/min ; Pressure after the implementation of the ventilation and fire prevention technology, debugging and implementation process should pay attention to the relevant matters and the effect of before and after the implementation of all pressure ventilation technology is analyzed and compared, the results show that pressure ventilation technology has signifi- cant effect in terms of governance goaf air leakage and can have fire prevention effect, effectively ensure the fully mechanized working face of production safety.
