摘要/Abstract

摘要： 为降低综采工作面空气粉尘浓度,减小粉尘对矿工及设备的危害,在西山煤田3号煤层开展煤层注水试验。通过测量固定测点粉尘的质量浓度及分散度,分析煤层注水的效果及其对综采工作面粉尘浓度和粒径分布的影响。结果表明:试验煤层单孔设计注水量440 m³条件下,煤层内在水含量平均增加1.02%,外在水含量平均增加了2.21%;注水后煤尘粒径分布范围变窄,平均粒径减小,整个工作面空气中全尘浓度平均降低28%,呼尘浓度平均降低32%。

关键词: 煤层注水, 煤尘浓度, 中位径, 煤尘粒径, 降尘效果

Abstract: In order to reduce the coal dust concentrations at fully mechanized mining faces and the harm of dust to miners and equipment, coal seam water injection experiments were carried out at the test mining face of No.3 coal seam in Xishan coal field. Dust concentrations and dispersion were measured at the measuring points of the mining face to analyze the coal seam water injection effect and its effects on the dust concentration and the particle size distribution. The results show that when the amount of water injected into the test seam through a single hole is 440 m³,the internal water content increases by average 1.02%, the external water content increases by average 2.21%, the distribution interval of coal dust particle sizes becomes shorter, the average particle size decreases, the total dust concentration at the whole mining face decreases by average 28%, the respiratory dust decreases by average 32%.

Key words: coal seam water injection, coal dust concentration, median particle size, coal dust particle size, dust reducing effect
