摘要
通过对采煤机产尘机理及静压除尘原理的分析,结合长期综采面采煤机降尘经验,提出了一种新的采煤机降尘方法,并对该方案进行了论述,依旧该方案对其降尘效果进行了实际验证。验证结果表明在采用该采煤机降尘装置后能够将降尘点空气中全尘和吸尘的质量浓度降低85%以上,具有非常理想的降尘效果。
Based on the analysis of the dust production mechanism of shearer and the principle of dust removal with static pressure, combined with the long-term experience of dust removal of shearer in fully mechanized face, a new method of dust removal of shearer is put forward, and the scheme is discussed, and its dust removal effect is verified in practice as before. The verification results show that the dust-removing device of the shearer can reduce the mass concentration of total dust and dust collection by more than 85% in dust fall point of the air, which has a very ideal dust-removing effect.
