摘要
本文以锦瑞煤业8105综采面为工程背景,通过分析Y型、W型通风系统的漏风规律、对比Y型、W型通风模式通风数据后,选择切顶卸压沿空留巷综采工作面W型通风为最优通风方式。以综采工作最合理的通风系统为基础进行防灭火技术研究,减少采空区漏风,降低采空区风压,缩小采空区氧化带的范围,保证采煤工作面不发生火灾险情。
Taking 8105 fully mechanized face of Jinrui Coal Industry as the engineering background,this paper analyzes the air leakage law of Y-type and W-type ventilation system,compares the ventilation data of Y-type and W-type ventilation mode,and selects W-type ventilation of fully mechanized face with roof cutting and pressure relief and gob side entry retaining as the optimal ventilation mode.Based on the most reasonable ventilation system of fully mechanized mining,the fire prevention and extinguishing technology is studied to reduce the air leakage in the goaf,reduce the air pressure in the goaf,narrow the scope of the oxidation zone in the goaf,and ensure that there is no fire danger in the coal mining face.
