摘要
以某煤矿S12003综采工作面为工程背景,研究分析采煤机上风侧滚筒截煤时,机身段附近的风速和粉尘分布特点,并对采煤机机载式喷雾控降尘装置进行优化设计,最终使采煤机截煤时采煤机司机处的总粉尘和呼吸性粉尘降尘效率分别达到92.8%和86.3%,取得了显著的降尘效果。
Based on the S12003 fully mechanized coal face in a mine,researched and analyzed the characteristics of wind speed and dust distribution nearby shearer fuselage when the upwind side drum cut coal,and optimized the spray ejector equipment on shearer,eventually making the total dust and respirable dust concentration at the shearer driver achieve 92.8% and 86.3% respectively when shearer cut coal,and achieved significant effect of dust suppression.
