【摘要】：随着煤炭行业机械化和采掘速度的加快,工作面粉尘浓度越来越大,威胁着工人的安全。通过分析磁化降尘机理和磁化表面活性剂溶液降尘机理,以山西省某矿为例,确定了适合该矿综采工作面的最佳表面活性剂为LDLC表面活性剂及最佳浓度为0.1%,以及最佳磁化强度1000 m T和最佳磁化时间60 s,并根据结果设计磁化管路和添加装置。该措施在该矿回采工作面进行现场试验,使该工作面的全尘浓度降尘效果比常规措施提高72%左右,PM2.5降尘效果提高60%左右,有效改善了工作面的作业环境。
[Abstract]:With the acceleration of mechanization and mining speed in coal industry, the dust concentration in working face is increasing, threatening the safety of workers. Based on the analysis of the mechanism of magnetization dust reduction and that of magnetized surfactant solution, taking a mine in Shanxi Province as an example, The optimum surfactant is LDLC surfactant, the optimum concentration is 0.1, the optimum magnetization intensity is 1000 Mt and the best magnetization time is 60 s. According to the results, the magnetization pipeline and the adding device are designed. This measure is tested in the mining face of this mine, and the dust reduction effect of the whole dust concentration in the working face is increased by 72% or so compared with the conventional measures, and the dust control effect of PM2.5 is improved by about 60%, and the working environment of the working face is effectively improved.
