摘要:
为解决碎软煤层综掘面截割产尘及粉尘扩散严重的问题,基于对综掘面主要尘源现状及其扩散特性分析,探讨泡沫对粉尘的接触、吸附机制,采用正交实验法确定5种试剂的最佳质量分数配比为0.20%∶0.30%∶0.10%∶0.20%∶0.10%,结合工程实践应用,确定综掘工作面总粉尘和呼吸性粉尘的平均降尘效率分别高达82.03%和85.63%。研究结果表明:复配发泡剂的质量分数存在1个峰值点使得发泡性能最大化,而温度的升高对泡沫稳定性有着降低作用,水在一定矿化度内能提升泡沫稳定性和溶液产泡能力。研究结果可为解决碎软煤层综掘面粉尘扩散严重的问题提供有效参考。
Abstract:
In order to solve the problem of dust production and dust diffusion during the cut-off in the fully mechanized excavation face of broken soft coal seams,based on the analysis of the current situation of main dust sources at the fully mechanized excavation face and their diffusion characteristics,the contact and adsorption mechanism of foam on dust was explored,and the optimal mass fraction ratio of 5 reagents was determined as 0.20%∶0.30%∶0.10%∶0.20%∶0.10% by using the orthogonal experiment method.Combined with the application of engineering practice,the average dust reduction efficiencies of the total dust and respiratory dust at the fully mechanized excavation face were as high as 82.03% and 85.63%,respectively.The results show that there is a peak point in the mass fraction of the compounding foaming agent to maximize the foaming performance,while the increase in temperature has a decreasing effect on the foam stability,and water within a certain mineralization degree can improve the foam stability and solution foaming capacity.The results can provide an effective means for solving the problem of severe dust dispersion in the fully mechanized excavation face of broken soft coal seams.
